KYA PR22 is an industrial pneumatic hog ring plier designed for 15 gauge D-style hog rings used in mattress production, automotive upholstery, furniture, wire cages, fencing, bag closure and related industrial fastening applications.
The tool weighs approximately 1.60kg and has a 150-ring magazine for repetitive production work. KYA lists an operating pressure of 4–7 bar, tool dimensions of 380 × 240 × 100mm and a 6mm air inlet.
PR22 is designed around the 15GA HR22-type D-ring class with approximately 22mm outside crown, 18.5–19mm inner open crown, 1.8mm wire and approximately 6–8mm finished closure. Ring geometry and collation should be confirmed before substituting another manufacturer's fasteners.

PR22 is designed for an industrial 15 gauge D-ring format rather than the common SC7 / C7 C-ring format. The compatible fastener class uses approximately 22mm outside crown, 18.5–19mm inner open crown and 1.8mm wire.
Market references for this general D-ring size include HR22, SR15 and BeA HR60-22-type fastening systems. Tool nose geometry, magazine design and ring collation can vary between manufacturers, so exact compatibility should be checked before ordering replacement rings.
The 22mm dimension refers to the approximate outside crown of the D-ring. The corresponding inner open width is approximately 18.5–19mm, commonly described as about 3/4 inch.
Using both measurements helps purchasing teams distinguish PR22-compatible D-rings from other 15 gauge C-ring products that may also be marketed using a nominal 3/4-inch size.
KYA lists the PR22 D-ring closure at approximately 6–8mm. Comparable 22mm D-ring systems commonly close to around 6.3mm or larger depending on the jaw configuration and the materials captured by the ring.
The required closure should be selected according to the spring wire, upholstery material, mesh, cord or other components being joined. A smaller closed diameter is not automatically better for every assembly.
The PR22 magazine holds up to 150 compatible D-rings. The extended loading capacity reduces the frequency of ring replacement during repetitive fastening in mattress, seating, cage and fencing production.
Use correctly collated strips and keep the magazine clean. Bent strips, damaged adhesive or incompatible ring geometry can cause feeding problems even when the wire gauge is correct.
The PR22 weighs approximately 1.60kg and is designed with balanced handling and a rubber grip for repeated industrial use. The pneumatic closing action reduces the manual force required compared with hand-operated hog ring pliers.
Tool balance and grip design can help reduce operator effort during repetitive assembly, but actual comfort depends on production position, hose arrangement, work height and fastening frequency.
KYA specifies a high-strength alloy steel muzzle for the PR22. The muzzle and closing jaws are critical wear components because they guide and form the D-ring during each fastening cycle.
Inspect the jaws regularly for wear, misalignment or damage. Worn closing surfaces can affect ring shape, closure diameter and production consistency.
Mattress and bedding production is a primary application for 15 gauge D-ring tools. PR22 can be used to close compatible D-rings around spring, border wire, fabric and other bedding components when the selected ring and closure match the assembly.
Production engineers should confirm the final ring closure around the actual spring and border-wire combination before establishing repetitive production settings.
Pneumatic D-ring tools are used in automotive and furniture upholstery to secure compatible fabric, listing wire, frame wire, webbing and related components.
Sharp-point or blunt-point rings should be selected according to whether material penetration is required. Tool access, ring closure and component dimensions should be checked on the actual seat assembly.
PR22 can also be used for compatible wire cages, fencing, mesh and netting where a 15 gauge 22mm D-ring provides the required finished connection.
For outdoor applications, select galvanized, Galfan, stainless-steel or other ring material according to moisture, salt, chemicals and expected service conditions.
D-ring systems are used in selected bag closure, netting and industrial binding applications where the material bundle fits within the ring's open and closed dimensions.
Blunt-point rings are often appropriate when piercing is not required, while sharp-point rings can be selected when the fastener must penetrate compatible fabric or mesh.

C-7EA, C-7CA52, SC7E and similar C7 tools should not be treated as direct PR22 fastener references simply because they also use approximately 1.8mm 15 gauge wire.
Comparable 15 gauge 22mm D-ring formats are sold under several industry naming systems. These references can help purchasing teams identify the correct general size class, but final compatibility should still be confirmed with the exact PR22 magazine and jaw geometry.

KYA lists a 4–7 bar operating-pressure range for the PR22. Use regulated, clean compressed air and adjust pressure according to the ring, material bundle and required closure.
Excessive pressure should not be used to compensate for incorrect fasteners or worn jaws. If rings close incorrectly, first check the ring series, magazine feed, jaw condition and tool setup.
Inspect the muzzle and closing jaws for wear or damage.
Keep the magazine and feed path clean.
Use only correctly collated 15GA 22mm D-rings.
Check air hoses and fittings for leakage.
Maintain regulated compressed-air pressure within the specified range.
Replace damaged or distorted ring strips before loading.
Disconnect the air supply before clearing jams or servicing the tool.
KYA supplies pneumatic hog ring tools and compatible D-rings for mattress manufacturers, automotive seating suppliers, furniture factories, cage manufacturers, fencing companies and industrial fastener distributors.
For a PR22 quotation, provide the required quantity, application, ring material, sharp or blunt point requirement, expected closure and air-supply specification. If replacing another D-ring tool, provide the existing tool and fastener model for compatibility checking.
KYA supplies pneumatic D-ring and C-ring tools in multiple gauges, crown sizes, magazine capacities and closure configurations for bedding, upholstery, automotive seating, fencing, cages, netting and industrial wire fastening.
PR22 uses 15 gauge D-style hog rings in the approximately 22mm outside-crown HR22 class.
The compatible D-ring wire diameter is approximately 1.8mm, corresponding to the common 15 gauge industrial hog ring class.
The approximately 22mm dimension refers to the outside crown of the open D-ring. The corresponding inside open crown is approximately 18.5–19mm.
KYA lists approximately 6–8mm closure for the PR22 D-ring system. Actual closure depends on the ring and jaw configuration.
The PR22 magazine capacity is approximately 150 compatible D-rings.
KYA lists the PR22 at approximately 1.60kg / 3.53lbs.
The listed operating-pressure range is approximately 4–7 bar / 58–102 PSI.
HR22 represents the same general 15 gauge 22mm D-ring size class used by the PR22. Confirm strip geometry and required closure before bulk ordering.
BeA HR60-22 / CL22 is a comparable 15 gauge 22mm D-ring market reference. Exact collation and magazine compatibility should still be confirmed before substitution.
C7E-type fasteners belong to a different 15 gauge C-ring system with approximately 23.7–24mm outside crown. They should not be listed as direct PR22 D-ring fasteners.
C-7CA-type tools use a 15 gauge C-ring format rather than the PR22 D-ring format. Do not assume interchangeability from wire gauge alone.
D-rings and C-rings have different open shapes, crown dimensions and closing geometry. They can require different jaws, magazines and fastener strips even when both use 15 gauge wire.
Yes. Bedding and mattress assembly are established applications for 15 gauge 22mm D-ring tools. Confirm the ring closure with the actual spring and border-wire combination.
Yes. Automotive seating and upholstery are common D-ring applications when the selected ring fits the seat wire, upholstery material and fastening location.
Yes. Wire cages, mesh and fencing are suitable applications where the 22mm D-ring and finished closure match the joined wires.
No. The tool is designed to reduce manual effort compared with hand pliers, but operator fatigue also depends on work position, production rate, air-hose routing and shift duration.
Use sharp-point rings where suitable material must be pierced during fastening. Use blunt-point rings where piercing is unnecessary and the ring only needs to close around the components.
Provide the application, required quantity, current ring or tool model, ring material, sharp or blunt point requirement, desired closure and available compressed-air specification.
