John Guest PM194E - 4mm O/D Collet Cover

The John Guest PM194E is a collet cover designed for use with 4mm outside diameter (O/D) tubing. The collet cover is a component used in quick connect fittings to secure the tubing in place and prevent it from being pulled out.

The PM194E collet cover is made of acetal plastic, which is a strong and durable material that is resistant to corrosion and chemicals. The cover is designed to fit over the collet, which is the part of the fitting that grips the tubing and creates a seal.

To use the PM194E collet cover, you simply push it over the collet after inserting the tubing into the fitting. The cover snaps into place, providing an additional layer of protection against accidental disconnection or tampering.

Overall, the John Guest PM194E collet cover is a reliable and convenient component for quick connect fittings with 4mm O/D tubing.
