Couplings

PVC Fittings Online now supplies couplings for PEX systems. These couplings have barbed crimp ends, so making connections with PEX tubing is straightforward and simple. PEX couplings connect two pieces of PEX tubing, usually to extend or reduce a pipeline. If a piece of tubing is not long enough to reach its destination, a coupling is needed to extend it. If you want to make the pipeline smaller, thus increasing flow pressure, a reducer coupling is used. There are many situations in which PEX couplings are helpful, but these are just a few of the most common. Browse our selection below.

Additional PEX Coupling Info

These couplings and reducer couplings are easy to incorporate into PEX systems. All you need are crimp rings and a crimp tool for a strong and durable connection. While some PEX fittings are made of brass, our couplings are composed of polyalloy. Polyalloy is an extremely corrosion-resistant material that is less susceptible to chemicals and less expensive than brass, making it an ideal alternative. If you have any more questions about any of our PEX couplings, feel free to give us a call at (866) 777-7990 or click the "Ask Question" button on any product page!
