The KYA HR22 Pneumatic Hog Ring Gun is an air-powered D-ring fastening tool for bedding, seating, upholstery, cage assembly and bag-closure applications. The current KYA product page specifies 15 gauge / 1.8mm D-ring fasteners, a 22mm crown reference, 6–8mm closed-ring range and a 50-ring magazine capacity.
The HR22 measures 260 × 240 × 60mm and has a published net weight of 1.58kg / 3.48 lbs. The current product specification also identifies a high-strength alloy-steel muzzle, rubber comfort grip and a balanced tool design.
For replacement D rings, do not match the tool by the HR22 name or 22mm dimension alone. Confirm the D-ring profile, wire diameter, open-ring dimensions, closure range, strip collation and magazine geometry before using another fastener system.

Important fastener-dimension note: the current HR22 tool page identifies a 22.0mm crown reference, while KYA's separate HR22 D-ring page identifies the corresponding 15GA fastener with a 3/4-inch / approximately 19mm crown. The current public pages do not explain the measurement difference. Confirm the production drawing before publishing one value as a universal open-crown specification.
The current HR22 tool page specifies 15GA / 1.8mm D-style hog rings. D rings have a different open geometry from C-style hog rings and should not be treated as interchangeable simply because the wire gauge is similar.
KYA's related HR22 fastener page identifies the fastener as a 15GA D Ring with a nominal 3/4-inch / 19mm open crown and approximately 1/4-inch / 6.4mm closed I.D. for its standard configuration. The HR22 tool page, however, uses a 22mm crown reference and a 6–8mm closure range. Buyers should use the current production drawing to reconcile those measurements before cross-brand substitution.
Hog-ring specifications can reference different points on the open fastener geometry. This matters because published dimensions from different suppliers are not always directly comparable from one number alone.
For example, KYA's HR22 tool page uses a 22mm crown reference, while its related fastener page uses 19mm. A current Meite D-ring system also describes a 22mm outside crown but uses 1.4mm wire rather than the 1.8mm wire published for KYA HR22. Therefore, a shared 22mm value does not prove fastener interchangeability.
| Reference | Published Ring Data | Compatibility Meaning |
|---|---|---|
| KYA HR22 Tool Page | 15GA / 1.8mm, 22mm crown reference, 6–8mm closure | Primary tool-page specification for KYA-HR22 |
| KYA HR22 D-Ring Page | 15GA / 1.8mm, 3/4" / 19mm crown, approximately 6.4mm closed I.D. | Related KYA fastener reference; measurement difference should be confirmed from the production drawing |
| Spotnails HRD34LM System | 15GA, 3/4" / 19mm open D ring, 6–10mm closure | Same general 15GA D-ring market class; not proof that KYA HR22 uses identical strip and nose geometry |
| Meite PHD-B System | 22mm outside crown but 1.4mm wire | Shows why a 22mm dimension alone is insufficient for compatibility matching |
The HR22 tool page explicitly identifies 15 gauge / 1.8mm D-ring wire. This wire dimension is one of the key specifications to check when sourcing replacement hog rings.
Do not substitute a thinner D ring solely because the open crown looks similar. Wire diameter changes the fastener profile and may also affect the magazine, nose and final clinch geometry.
KYA publishes a 6–8mm D-ring closure range for the HR22 tool. The final closed shape should be evaluated with the actual ring, application material and tool configuration rather than treated as an independent guaranteed dimension for every fastening joint.
Current professional competitor systems also publish closure dimensions as a core matching parameter. Spotnails, for example, specifies 6–10mm for its HRD34LM 15GA D-ring tool. That difference is another reason not to assume universal cross-brand compatibility.
The current KYA HR22 specification lists a 50-piece load capacity. This should be treated as the magazine capacity for the KYA-HR22 configuration rather than a general capacity for every 15GA D-ring gun.
Competitor tools use different magazine lengths and capacities. Spotnails HRD34LM currently lists 125 rings, while Meite PHD-B lists 100 rings. Magazine capacity therefore does not establish ring interchangeability between systems.
The current HR22 specification identifies a high-strength alloy-steel muzzle. The nose assembly is the part that positions and closes the D ring, so the exact ring geometry must match the tool's muzzle profile.
KYA also specifies a rubber comfort grip and describes the tool as using a balanced design. These are physical design features of the current HR22 product; the page does not publish a quantified fatigue-reduction or productivity test.
Several professional hog-ring systems use 15GA D-style rings, but their magazine capacities, closure ranges, open-ring measurements and ring dimensions differ. Use competitor references to identify the market class, not as automatic proof of interchangeability.
| Tool System | Published Fastener / Tool Data | Matching Guidance |
|---|---|---|
| KYA HR22 | 15GA / 1.8mm D ring, 22mm crown reference, 6–8mm closure, 50-ring capacity | Featured product on this page |
| Spotnails HRD34LM | 15GA D ring, 3/4" / 19mm open ring, 6–10mm closure, 125-ring magazine | Comparable 15GA D-ring system; verify KYA ring dimensions, strip and nose geometry before substitution |
| Spotnails RH22 | Listed by Spotnails as a tool for its 69012 15GA 3/4" D hog rings | Useful cross-reference name only; not a verified KYA-HR22 interchangeability statement |
| BeA HR60-22 | Listed by Spotnails as a tool using the same 69012 15GA 3/4" D-ring market class | Verify exact fastener and tool geometry before using a KYA ring as a replacement |
| Bostitch TR201 / TR203 / TR315B | Spotnails lists these as references for its 69012 D-ring system | Industry reference only; no unconditional KYA-HR22 compatibility claim should be made |
| Meite PHD-B | 22mm outer crown, 1.4mm wire, 100-ring magazine | Published wire diameter differs materially from KYA HR22's 1.8mm specification |
A pneumatic hog ring tool must feed and close the exact fastener geometry it was designed for. Compatibility depends on several dimensions at the same time, including wire diameter, open crown, overall ring profile, strip collation, magazine track, nose geometry and closed-ring requirement.
When replacing an existing tool or D ring, provide the current tool model and fastener number together. This is more reliable than ordering from a generic description such as “15GA 22mm hog ring.”
Spring mattress manufacturing is a primary application listed on the current KYA HR22 page. D rings can be used to clinch compatible wire, spring and upholstery components where the HR22 ring geometry matches the joint.
KYA lists automotive upholstery and seating among HR22 applications. For production seating work, verify the specified ring material, point geometry and closure requirement for the actual assembly.
Pet-cage assembly with mesh structures is listed on the current product page. The ring material and finish should be selected according to the actual wire diameter and environmental exposure of the cage system.
Bag closing is another published HR22 application. Confirm that the selected 15GA D ring and final closure are appropriate for the bag material and closure construction.
| Parameter | KYA HR22 Reference | Why It Matters |
|---|---|---|
| Fastener Style | D Ring | C rings and D rings use different open geometries and may require different nose and magazine designs |
| Gauge | 15GA | The tool page specifies this gauge class |
| Wire Diameter | 1.8mm | Different wire diameters can change both magazine fit and final clinch geometry |
| Crown / Open Ring | Tool page: 22mm reference; related KYA ring page: 19mm / 3/4" crown | Confirm the current drawing because the public KYA pages use different measurements |
| Closure | 6–8mm on the current HR22 tool page | The closed ring must suit the material or wire bundle being fastened |
| Collation | Use the strip format specified for the HR22 magazine | Correct spacing and strip construction are required for reliable magazine feeding |
| Point Type | KYA's related HR22 ring family lists sharp and blunt configurations | Confirm which point is required for the actual material and current tool configuration |
The current KYA product page states that the HR22 is packed with 200 D-ring staples and one toolkit in the carton box. The page does not publish a complete itemized toolkit list.
If accessories are important to a purchase order, identify the required components separately rather than assuming that a specific air fitting, oil bottle, wrench or spare part is included.

HR22 is a pneumatic D-ring fastening tool identified by KYA as model HR22 and product code KYA-HR22.
The current KYA HR22 tool page specifies 15 gauge / 1.8mm D-ring fasteners.
The current product specification identifies D-style hog rings. Do not substitute C rings unless the tool manufacturer specifically confirms that fastener geometry.
The current HR22 tool page lists a 22.0mm crown reference. KYA's separate HR22 D-ring page lists the related fastener at 3/4 inch / approximately 19mm crown. Because the public pages do not explain this measurement difference, confirm the current production drawing before using the crown value for cross-brand qualification.
The HR22 tool page publishes a 6–8mm closure range. KYA's related HR22 fastener page describes approximately 6.4mm closed I.D. for its standard 3/4-inch configuration.
The current KYA specification lists a 50-piece magazine capacity.
The published net weight is 1.58kg / approximately 3.48 lbs.
The current product page lists 260 × 240 × 60mm.
KYA identifies the muzzle material as high-strength alloy steel.
The current KYA HR22 product page does not publish an operating-pressure value. Do not copy the PSI range from another 15GA D-ring tool because pneumatic specifications vary by model.
Spotnails 69012 is a 15GA 3/4-inch D-style hog ring used with its HRD34LM and RH22 tools. The current KYA HR22 page does not independently verify 69012 compatibility, so compare the complete fastener dimensions and strip geometry before substitution.
BeA HR60-22 appears in industry cross-reference data for the 15GA 3/4-inch D-ring class, but the current KYA HR22 tool page does not establish unconditional cross-brand interchangeability. Verify the exact fastener and tool dimensions first.
Spotnails identifies its 69012 D ring as interchangeable with Bostitch SR-15 within its own tool system. That does not by itself prove KYA HR22 compatibility. Confirm the KYA magazine, ring profile and closure geometry before use.
Do not assume so. The KYA HR22 page specifies 1.8mm wire. Some other 22mm D-ring systems use 1.4mm wire, which is a different fastener profile.
KYA lists spring mattress manufacturing, automotive upholstery and seating, pet-cage assembly and bag closures as primary applications.
Yes. Spring mattress manufacturing is specifically listed on the current KYA product page.
Yes. Automotive upholstery and seating are listed among the current HR22 applications. Confirm the required D-ring material, point style and closure for the actual seat assembly.
Pet-cage assembly with mesh structures is listed on the current KYA page. Verify the wire diameters, required ring closure and environmental exposure before selecting the fastener.
The current KYA product page states that the carton is packed with 200 D-ring staples and one toolkit. The page does not provide a complete itemized list of the toolkit contents.
Provide the exact tool model, current ring reference or drawing, wire diameter, open-ring dimensions, closure requirement, point type and strip collation. Do not qualify a replacement ring from the model name or crown dimension alone.
The KYA HR22 is positioned for mattress manufacturers, automotive upholstery operations, furniture and seating manufacturers, cage producers, fastener distributors and pneumatic-tool distributors requiring a 15GA D-ring fastening system.
For purchasing or replacement evaluation, provide the required tool quantity, intended application and existing D-ring or tool reference. Where fastener interchangeability is important, confirm the actual ring drawing before volume purchasing.
