KYA HR23 Hog Rings are 15 gauge C-style fasteners designed for automotive seating, furniture upholstery, mattresses, bedding, wire cages, fencing and other repetitive industrial fastening applications. The fastener uses approximately 1.8mm wire with a nominal 3/4 inch open size and an approximately 12mm open ring height.
HR23 rings are available in galvanized and stainless-steel configurations with sharp or blunt point options. Different compatible hog ring tools can form different final closure diameters, including approximately 3/16 inch and 5/16 inch configurations.
For replacement purchasing, confirm the exact ring geometry, wire diameter, point type, material and required closed-ring diameter against the pneumatic hog ring tool rather than selecting by the 3/4 inch description alone.

HR23 dimensions can be described differently by hog ring and pneumatic-tool manufacturers. The product is commonly marketed as a 3/4 inch C ring, referring to its nominal open or inner size.
Compatible C7-type tool specifications commonly describe the same fastener class as approximately 23.7–24mm outer crown, 1.8mm wire and approximately 12mm ring height.
For procurement, compare both the nominal 3/4 inch designation and the actual metric dimensions. This reduces the risk of ordering a C ring that has the correct general size but does not feed or close correctly in the intended tool.
The HR23 fastener can be formed to different closed-ring diameters depending on the jaw configuration of the hog ring tool. Common references include approximately 3/16 inch and 5/16 inch closures.
| Closure Reference | Selection Consideration |
|---|---|
| Approx. 3/16" / 4.8mm | Tighter closure used by compatible tools such as C-7CA52-type jaw systems. |
| Approx. 5/16" / 7.9mm | Larger finished ring diameter for applications requiring more space around the joined components. |
The required closed diameter should be selected according to the wire, spring, fabric or frame components being joined. A tighter closure is not automatically better for every application.
HR23 C rings use approximately 1.8mm diameter wire, corresponding to the common 15 gauge upholstery hog ring class.
This wire size is widely used for automotive seating, furniture and bedding applications because it can be formed around compatible springs, wire, fabric and frame components with pneumatic C-ring tools.
Holding performance depends on ring material, closure diameter, tool jaw geometry and the components being joined. Production assemblies should be tested under the intended service conditions.
| Point Type | Typical Selection Guidance |
|---|---|
| Sharp Point | Useful where the ring needs to pierce suitable fabric, upholstery material, mesh or other compatible material before closure. |
| Blunt Point | Useful where piercing is unnecessary and reduced risk of puncturing nearby material is preferred. |
Select the point according to the actual material and assembly process. Sharp and blunt fasteners should not automatically be substituted without checking the final joint.
Galvanized steel is commonly selected for automotive seating, furniture, mattresses and other indoor industrial assemblies. The zinc coating provides additional corrosion protection compared with untreated steel.
Stainless steel should be considered where greater resistance to moisture, outdoor exposure, salt or other aggressive environments is required.
Material selection should follow the actual operating environment. Standard galvanized rings should not automatically be treated as equivalent to stainless steel for long-term outdoor or marine exposure.
HR23 belongs to a 15 gauge C-ring class used by several automotive, bedding and upholstery hog ring tools. Compatibility depends on the complete ring geometry and required closure.
| Tool Reference | Compatibility Guidance |
|---|---|
| KYA C-7EA | Designed for 15GA, approximately 23.7–24mm outer-crown C rings including HR23, 15G100, SC-6 and C24. |
| KYA C-7CA52 | Uses 15GA, approximately 23.8mm crown, 1.8mm wire and 12mm-height C rings with approximately 4.8mm closure. |
| Spotnails HRC34-Type Tool | Uses 15GA 3/4-inch open C rings. Confirm actual closure range and ring profile before substitution. |
| Other HR23 / C7-Type Tools | Confirm gauge, crown, ring height, magazine, point type and final closure diameter. |
Do not assume that every pneumatic tool described as a 3/4 inch hog ring gun will accept HR23 rings. Different tools can use different wire gauges, ring profiles and closure jaws.
Automotive seating is one of the primary applications for 15 gauge C-ring systems. HR23 rings can be used to secure upholstery components, listing wires, springs and compatible seat-frame elements.
The pneumatic tool forms the open C ring around the joined components. Final ring diameter should provide secure retention without excessively crushing or damaging the upholstery, wire or frame component.
Mattress and bedding manufacturers use 15 gauge C rings to connect compatible border wire, springs, fabric, insulation and other bedding components.
The correct closure size depends on the wire diameter and components being captured by the ring. A 3/16 inch closure should not automatically be treated as the best option for every spring or border-wire assembly.
Furniture factories and upholstery shops can use HR23-type C rings to secure compatible springs, webbing, upholstery material and frame components.
Sharp-point rings may be selected where penetration is required, while blunt-point rings are useful where the fastener only needs to close around the joined parts.
HR23 rings can also be used to close compatible wire mesh, animal cages, netting and fencing assemblies where the closed ring fits the wire combination.
For exterior, wet or corrosive installations, select the material according to the expected environment. Stainless steel or another specified corrosion-resistant material may be more appropriate than standard galvanized steel.
