Asked by Sergey 13 years ago

Verified Reply- PexSupply StaffThis fitting is compatible with any standard 3/8" PEX, including Mr. PEX tubing.
Having bought this product, I can honestly say that it IS compatible with 3/8 " tubing and that it is easy to attach. -----Original Message-----
Q: Can I use this on my watts radiant manifold? if not, how how how, can I hook up the 5/16 pex I already ran in quicktrack to my watts manifold?
Asked by Geoff 13 years ago
Add your answer
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.
looks like its the same as all the other fittings its just the feral and the adapter that is different
Only if the Watts manifold has R20 threads.

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?
Asked by elbill 14 years ago

Verified Reply- PexSupply StaffYou can reuse the fittings, but we'd recommend that you cut off the used end of the tubing where the existing fitting was installed.
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. --Mike
you can reuse the fittings, but the split rings and o rings should be replaced.
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.
If pass pressure test you can re-use.
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.
Yes you can use the same fittings as long as you cut pex ttubing and use a clean end. Good luck.
Q: I AM USING THE TRUFLOW MANIFOLDS SYSTEM. I RAN 1/2"HEPEX. WHAT FITTING DO I NEED FOR THE LOOP CONNECTION?
Asked by roger 14 years ago
Add your answer
Verified Reply- PexSupply StaffThis (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.
Q: Can these connect 5/16" hepex to Rifeng ss manifold? If not what would be the correct adaptor?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThese 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.
