What a great connector for odd size PEX tubing. It was simple to install and accepted the conversion nipple so a hose could be attached.

      Yes, the compression fitting on one side will accept your 5/16 pex and the
      r20 thread on the other side will thread into the manifold.

    Q:

    I need to move my manifold and shorten up the tubing on the supply side. These fittings were used for connecting and have passed a pressure test however have not gone thru a heating sesason yet. Can I re use these fittings or do I need to replace them?

      A:

      I've re-used that fitting before with good results. Do NOT re-use it if the
      threads are damaged or stripped, and do NOT nick up the compression sleeve
      with your pliers removing it from the tubing. Been there done that. I
      learned to always have an extra fitting lying around just in case. Good
      luck.

      A:

      You may need to replace the ferrule, but the other fittings should be
      fine. Check the o-ring and replace if it is damaged, otherwise you may
      want to apply a very small amount of lubricant (silicone grease works)
      to the o-ring to make it slide into the mating fitting easier. I have
      reused this type of fitting several times with no problem. The sealing
      surfaces are the barb and the o-ring, so make sure those are not damaged.

      If pass pressure test you can re-use.

      A:

      Check the compression ring. If there's no nicks, you should be able to
      reuse them. If not, you can just get the rings. The threaded fittings
      should be good to go.

      I have reused these fittings successfully. You may have to replace
      the compression rings. PexSupply sells the replacements.

      you can reuse the fittings, but the split rings and o rings should be replaced.

      Yes you can use the same fittings as long as you cut pex ttubing and use a clean end. Good luck.

      A:

      You can reuse the fittings, but we'd recommend that you cut off the used end of the tubing where the existing fitting was installed.

      A:

      This (part A4020500) is the fitting you need to make a compression connection with 1/2" PEX and the TruFLOW manifold. You can use part Q4020500 to make ProPEX connections if you have the proper tool.

    Can these connect 5/16" hepex to Rifeng ss manifold? If not what would be the correct adaptor?

    • CUSTOMER CARE

      A:

      These fittings would not work, as Rifeng manifolds use a different thread style. Unfortunately there are no 5/16" fittings that are compatible with Rifeng manifolds.
