The Best Fittings 1/4" BSP Bonded Seal Washers (5 Pack) are designed to provide a reliable, leak-free seal when connecting 1/4" BSP male fittings to a flat sealing surface. Commonly used on airgun charging cylinders, these bonded seal washers are the standard size used on DIN male to hose connections, making them an essential spare for maintaining your charging equipment.
Manufactured to ensure a secure seal under pressure, each washer combines a durable metal outer ring with an integrated rubber sealing insert, allowing the fitting to compress evenly and prevent air leaks when tightened. This design ensures consistent performance when used with parallel BSP fittings, particularly in high-pressure charging setups.
Each washer is designed to fit 1/4" BSP male threads with a physical thread outside diameter of approximately 1/2" (13.1mm), ensuring compatibility with common airgun charging components. Supplied in a convenient pack of five, they provide a practical solution for maintenance, replacements, or keeping essential spares in your workshop or range kit.
