John Guest PM198S - 5/16" O/D Collet Cover Grey

The John Guest PM198S is a collet cover designed for use with 5/16" outside diameter (O/D) tubing. It is gray in color and is used to cover the collet (a type of mechanical clamp) that holds the tubing in place in a John Guest push-fit fitting.

The collet cover serves a few purposes. Firstly, it helps to protect the collet from damage or wear, which can help to ensure that the fitting maintains a secure hold on the tubing over time. Additionally, the cover helps to provide a neat and tidy appearance to the fitting, which can be important in applications where aesthetics are important.

Overall, the John Guest PM198S collet cover is a small but important component in a push-fit plumbing system, helping to ensure reliable and secure connections between tubing and fittings.
