5/8" PEX Compression adapters are used to connect 5/8" PEX tubing to the radiant heat manifold's outlets.

Each adapter consists of a PEX insert, a compression ring and a nut.

PEX insert is crimp style, and is compatible with all types of 5/8" PEX tubing (A, B or C), including Everhot, Watts, Zurn, Nibco and many other brands.

These adapters do not require any PEX tools or rings - simply use a crescent wrench or adjustable pliers to tighten the nut over the manifold outlet.


Adapters are free with any manifold purchase - leave a note at the checkout page to request any particular size of adapters.

Does this fit on a 1/2" manifold
Read 1 answer
These adapters will fit the SSM or BSM series radiant manifolds. The manifold outlet connections are the same on all models and PEX adapters - only the PEX sizes are different.
