3/4″ PEX Compression Manifold Adapter

3/4″ PEX Compression adapters are used to connect 3/4″ PEX tubing to the PEXGUY and Rifeng radiant heat manifold’s outlets. These connectors will ONLY fit the Rifeng Deluxe Brass and Stainless Steel Manifolds.  They will NOT work with our Classic manifolds or copper Sioux Chief manifolds.  We reserve the right to cancel or limit orders depending on availability and/or if they will be used with PEX GUY Manifolds.

Each adapter consists of a PEX insert, a compression ring, a nut and threaded adapter for 3/4″
Compatible with all types (A, B, C) and makes of 1/2″ PEX tubing manufactured to ASTM F876/877 standard (Everhot, Watts, Viega, Zurn, Nibco, etc.)

Note that a PEX tool is not required to connect the PEX tubing to the manifold. Instead, use adjustable pliers (such as Channellocks) or a crescent wrench to tighten the nut over the manifold’s outlet.

We cannot guarantee compatibility with other manifold brand aside from the ones we sell. However, they are compatible with all types of PEX (A, B, C) and makes of PEX tubing manufactured to ASTM F876/877 and SDR-9 dimension standard. These cannot be used with PEX AL PEX tubing. Please purchase the PEX AL PEX tubing adaptors.

No special tools needed, just a standard wrench.
