Description
High-Performance NBR Replacement for Vintage Leather Seals
Traditional leather breech washers dry out, crack, and require constant oiling to maintain a seal. Our NBR rubber breech seals eliminate that maintenance. Nitrile butadiene rubber (NBR) is highly resilient, offering excellent resistance to compression set, wear, and mechanical tearing while providing an airtight closure.
Precision Fit and Better Velocity
A leaking breech face drops your velocity and ruins downrange groupings. This synthetic upgrade fits directly into the factory breech groove, sealing completely against the compression face without expanding, shrinking, or losing its shape over thousands of firing cycles.
Key Benefits & Performance Features
- Durable NBR Construction: High-grade Nitrile rubber outlasts organic leather and won’t dry out or rot.
- Multi-Brand Fitment Matrix: Custom moulded to fit a wide cross-section of break-barrel models, including Lucznik, Haenel, Diana, Winchester, and Beeman.
- Zero-Oil Maintenance: Unlike leather, it requires no soaking or conditioning oils to stay flexible and functional.
- Restores Original Power: Eliminates micro air leaks at the breach face to give your air rifle consistent velocity.
- Slightly Modifiable: Easily shimmed or lightly sanded if your specific vintage airgun breech depth varies slightly due to factory age variances.
