Caleffi 680555A 5/8" PEX Fitting for Manifolds, Threaded, for Caleffi 663 and 668S1 Series Manifolds

The Caleffi 680555A is a 5/8" nominal PEX fitting used to connect PEX tubing to the outlets of a Caleffi manifold. It is listed for use with the Caleffi 663 and 668S1 series manifolds.

Fittings like this one terminate each PEX loop or branch line at its supply or return outlet on hydronic, radiant and plumbing distribution manifolds, with a threaded connection on the manifold side.

Before ordering: confirm that your tubing is 5/8" nominal PEX (not PEX-AL-PEX) and that the manifold is a Caleffi 663 or 668S1 series model. One fitting is needed per tube end.
