John Guest PM051514E - 1/2" BSPP Male x 15mm O/D Stem Adaptor

The John Guest PM051514E is a plumbing component that is used to connect a 1/2 inch BSPP (British Standard Pipe Parallel) male fitting to a 15mm outside diameter (O/D) stem.

The BSPP male end of the adaptor has a parallel thread with a diameter of 1/2 inch. The parallel thread means that the fitting can be screwed directly into a female BSPP thread without the need for a sealing washer.

The 15mm O/D stem end of the adaptor is designed to be pushed into a tube or hose with a 15mm inside diameter, creating a secure and leak-free connection. The stem features John Guest's proprietary push-fit technology, which allows for easy installation and removal without the need for tools.

This type of adaptor is commonly used in plumbing applications where different types of fittings need to be connected together. It is important to ensure that the BSPP male end of the adaptor is compatible with the female fitting it will be connected to, and that the 15mm O/D stem is the correct size for the tube or hose being used.
