This collet cover is designed to provide additional security for John Guest push-fit connections by preventing accidental pipe disconnection or tampering. It is an important safety accessory in compressed air and pneumatic systems, particularly in exposed or high-traffic environments.

The cover locks over the collet of a push-fit fitting, restricting access to the release mechanism and ensuring the pipe remains securely in place. It can be fitted either before the pipe is inserted or slid into position afterwards, offering flexibility during installation or retrofit.

Manufactured from durable engineered plastic, the collet cover is suitable for use across a wide range of applications, including air, inert gas, vacuum and potable liquid systems. Designed, manufactured and assembled in the UK, it delivers reliable performance and peace of mind.
