Is your air nailer's dust cap missing or worn out? The O-Ring Depot has engineered the perfect, durable replacement. Our cap is designed with a beefed-up thickness and extra length to provide a secure fit that lasts longer than the original.
By purchasing this product, you're not just getting a high-quality dust cap—you're supporting American manufacturing. Our caps are designed and 3D printed in Houston, Texas, in a print farm owned and operated by a 100% service-connected disabled veteran.
Engineered for Durability. Unlike rigid plastic caps, ours is 3D printed with TPU (Thermoplastic Polyurethane), an exceptionally flexible and resilient material. TPU is resistant to abrasion, oil, and grease, making it the ideal choice for the rugged demands of any job site.
This replacement dust cap was redesigned in Autodesk and then 3D printed using TPU. We've beefed up the thickness all around and made it a little longer than standard caps.
Designed to fit the SWIVEL 1/4 NPT with a .75" interior diameter and overall longer to fit the needs of a swivel connection. We couldn't find any on the internet, so we made one.
These caps are designed to fit a standard 5/16" (.3215) nipple, which comes with most air nailers.
Please check to make sure your nipple is the correct size before ordering.
This seal is manufactured from TPU (Thermoplastic Polyurethane), a high-performance material chosen for its superior properties:
Excellent Sealing: TPU provides a robust, airtight seal to maintain consistent tool performance.
Flexibility: Offers rubber-like elasticity to handle the dynamic conditions inside the tool.
Upgrade your nailer's reliability with this high-quality TPU seal!
Important Notes:
Nail gun and swivel connector are NOT included in this listing. It is only for the dust cap pictured.
The color of parts will vary based on the batch and material used.
✅ Don't be fooled by ads saying "US SHIPPED" or "U.S. Stock." Always check the seller's location. Keep that in mind when you spend your dollars, buy American and American-made!
