Questions & Answers

Can this fitting be used to join polyb and PEX-A with a crimp tool? The PEX-A version is expansion only, I don’t have an expansion tool and need to make a quick repair.

Answer This Question

Yes, PEX-A is dual-rated, so it can be crimped with this fitting to transition from PEX-A to polybutylene.

    I am looking for a straight coupler to join 1/2-in PEX B to 1/2-in braided PVC hose in an RV fresh water system. Will this 1/2-in PEX B by 1/2-in polybutylene coupler work for this application?

            can clamp fittings be used with this fitting on both the pex and pb?

            Answer This Question

            The Apollo 3/4 in. Brass PEX Barb Polybutylene Coupling has one barb that must be conjoined to PEX pipe and the other barb must be secured to polybutylene pipe. The three barbed inlet is for PEX and the five barbed inlet is for polybutylene. To secure the fitting to PEX and polybutylene pipe you may use the crimp rings that come with this fitting or pinch clamps (sold separately). If you have further questions, please give us a call at 888-229-2874.

              Which way round to the rings and fittings go on the poly/pex pipe. Cannot find this online or is it obvious?
              ByAug 16, 2020
              1 Answer | 
              Answer This Question

              One side of the fitting has five barbs and the other side of the fitting has three barbs. The five barbed side of the fitting is for use with polybutylene and the three barbed side of the fitting is for use with PEX. Use the copper colored crimp ring to secure the polybutylene pipe and use the black colored crimp ring to secure PEX pipe to the fitting.

                  Have used these on multiple occasions to repair the polybutylene in my 1995 mobile home. So far they have worked perfectly every time!
