What a PE male and female adaptor is
A compression male and female adaptor, also called a PE threaded adaptor, is a fitting whose one end closes onto polyethylene pipe like any compression fitting, while the other end is threaded. It connects PE pipe to a threaded valve, a pump outlet, a water meter, a brass gate valve or any other threaded part.
In the male version the thread is on the outside and screws into a female part; in the female version the thread is inside and a male part screws into it. To choose correctly, check whether the part you are connecting to has an outside or an inside thread.
Adaptor sizes: pipe diameter and thread size
Each adaptor is identified by two numbers: the PE pipe outside diameter in millimetres and the thread size in inches. Our published rows cover 16, 20, 25, 32, 40, 50, 63, 75, 90 and 110 mm with the matching market thread size, for example 63 mm pipe with a 2 inch thread and 110 mm pipe with a 4 inch thread.
If you need another combination, such as 32 mm pipe with a 1/2 inch thread for a small valve, put it in your enquiry too. State the thread type (male or female) and the quantity so the right part is supplied.
Installation and sealing the thread
The compression side is fitted like any compression fitting: cut the pipe square, slide the nut and grip ring on, push the pipe fully home and tighten the nut by hand and then with a strap wrench. Wrap the thread side with PTFE tape or a suitable thread sealant before screwing it in.
Do not overtighten a plastic thread, as it may crack. If the mating part is heavy metal, such as a valve or meter, support it separately so that its weight does not hang on the adaptor and pipe.
