Leak-proof your keg and homebrew regulators! Kegconnection offers Ten-Regulator nylon washers for use between CO2 cylinder and regulator. These regulator washers are made with high-quality plastic nylon material to match your commercial-grade homebrew, keg, draft beer kegerator and other beer regulators. This washer provides air tight seal between your keg regulator and CO2 cylinder tank. This prevents pressure and air loss so your keg system dispenses properly. It's not unusual to misplace or lose your washers in between beer line cleaning or keg maintenance. This replacement washer has universal design and size that fit most kegerator regulators, making it a great spare tool to have at home or in your restaurant bar. You can easily replace your lost or broken washer with our regulator washers as it's very easy to install. A must have for air loss from co2 tank to regulator! However, you do not need to (want to) use this washer on a Taprite regulator because it has a built in O-ring.
