The John Guest Speedfit Collet Cover (PM1915B) is an essential safety accessory for professional plumbers and DIY enthusiasts working with 15mm push-fit plumbing systems. It provides a secure way to prevent accidental collet release or tampering, ensuring that pipe connections remain intact under pressure. While these covers offer significant peace of mind and visual organization, they must be used correctly on compatible John Guest fittings to ensure a proper fit and locking mechanism.

Yes, they are rated for standard hot water and central heating system temperatures.
Gently pry the edge of the cover away from the fitting with a small tool until the tabs release, then remove it completely before operating the collet to release the pipe.
Check that the fitting is a genuine 15mm John Guest Speedfit component and ensure no debris is obstructing the collet.
Verify that the cover is pushed fully against the fitting body; if it remains loose, the collet may be damaged, and the fitting should be inspected.
Setup
Installation is straightforward. Simply align the collet cover with the front of the fitting. Apply firm, even pressure until the cover clicks securely into place around the collet collar. It can be installed before you insert the pipe into the fitting or as a final step after the connection has been made.
Compatibility
This model (PM1915B) is exclusively designed for 15mm John Guest Speedfit push-fit fittings. Ensure that you are using genuine John Guest components to guarantee the intended locking function and seal.
Care
These covers are maintenance-free. However, if you need to disassemble a joint for plumbing repairs, the cover must be removed first. Use a flat-head screwdriver or your fingernails to gently pry the cover off the collet, then follow standard procedures for releasing the John Guest push-fit pipe.
