Happy to find this compression fitting.

I was running some Pex Al Pex to replace some old black pipe heating lines to my radiators. The radiators were connected with copper to black pipe and this was causing the pipes to corrode. I already had the Pex Al Pex as I had used it before and I only had one set of compression fittings. I know that press fittings could also work but I did not have the tools and it cost a lot. I am just a homeowner doing my own repairs so I was looking for compressing fittings. I checked all of my local stores but they were not available. I then checked online and found them at SupplyHouse. They were perfect for the job and they were shipped very quickly. SupplyHouse had a wide selection of fittings and pex tubing. I even purchased 100' of Pex type A because I could not find it in local stores. SupplyHouse had all of the items I needed and they were delivered very quickly. Thanks for having the latest in Plumbing and Heating supplies.

Can't solder 3/4" copper into the ID

Big downfall - Can't solder 3/4" copper into the ID of the fitting. MUST use 3/4" pipe thread coupling. So you need this fitting, 3/4" coupling or 90 and a 3/4" copper male adapter to go to copper pipe. The fitting works the way it is advertised, NO problem with the fitting. ADVICE - STAY AWAY FROM PEX-AL-PEX!! It is cheap but the fittings are almost impossible to find and if you do the selection is VERY limited and they can be expensive. Standard 3/4" pex anything will NOT work with Pex-AL-Pex.

Great hard to find compression fitting for Kitec

These fittings are hard to find in local stores. I had some 3/4 kitec that I needed to transition to copper and these worked perfectly.

Works Perfectly

I have used several of these fittings for pex al applications. They're not cheap, but they work great. SupplyHouse is an awesome company to deal with. Prompt delivery, fair prices, and outstanding customer service.

PERFECT fitting to connect 1/2" PAP to air compressor system

Unlike many other reviewers, I used 1/2" Pex AL Pex line as an air compressor line. These fitting are perfect to connect my air compressor to the overhead line, and at the other end to connect to my air hose reel. Supply House shipped my order the same day I placed my order, and I had my fittings in just a couple of days.

Came within two days of placing order

I cut a water line then realized it was kitec tubing. Nothing else would work except these fittings. Came fast and saved the day. Thanks...

Q: I'm getting a little confused. Many times there are conflicting answers regarding compatibility in these threads. In this case, the specs clearly say NSF approved, but the answer to potable water use says the item does not meet NSF cert. What's the deal???

NSF approved does not necessarily mean that the product is not approved for potable water use. In this case these fittings are approved by the National Science Foundation but are not to be used with potable water.

Peter, I think these Pex-al-pex fittings are made to common respective standard sizes – if it says it will work with ¾ or 1” pex-al-pex they should. I’ve found the fittings periodically need to be retightened over the years… especially when you let the system go cold in the summer – that’s when they’re prone to leaking. Brian

They will, as long as the tubing meets the specifications of standard PEX-AL-PEX (.490" ID and .636 OD for 1/2").

We would not recommend that you use anything on the compression side, due to the o-rings.

These fittings will not work with that tubing as per the manufacturer.

FYI--(I'm the original poster) I received these fittings (I had already ordered them) and right on the nut is stamped F1281-2005. Hurray for making my life easier!

Q: Is any type of expansion tool needed to affix the pex al pex tube onto the fitting securely, before tightening the fitting? Also, what is the best cutter for pex-al-pex?

You will need a chamfering tool to prepare the tubing for the fitting. Most PEX cutters also cut PEX-AL-PEX tubing.
