PEX Adapters

(35 products)

PVC Fittings Online now stocks a wide range of Brass & Poly Alloy PEX adapters. PEX adapters join two completely different pipelines together, allowing for customization of old pipelines or flexibility in new ones. If you want to update a copper plumbing system with some PEX sections without completely switching over, you can use one of these PEX adapters to join the two pipelines. If you want a plumbing system with more than one type of piping, these adapters are also useful, as they provide a clear and smooth transition from PEX to anything else.
