Kitec Tubing and fittings?

4Johnpipe Member Posts: 483
I came across a job where I was referred. The contractor(?) installed Kitec tube and brass fittings in a radiant/ baseboard heating system about a year and a half ago new home. The tubing is not common here. I looked it up and came across a lot of information regarding a class action suit regarding this material. Can anyone confirm the use for this product. I can not determine if 180 degree boiler water is approved the parent company IPEX seems to have discontinued the entire line. I am at a loss seeing this installed approximately 2 years after all the litigation and problems with the product.

    My understanding is that

    the issues were dezincification, crumbling fittings but only on domestic water systems, not on heating systems.  Anyone hear otherwise?

    (I have about 200 feet of 5/8" Kitec, a manifold fitted for 5/8" and a host of 5/8" Kitek K2 compression fittings, but not enough to complete a few radiator hook ups. Anyone have any to spare/sell? I cannot find them either.)

    But I can see the issue, once bitten, better to remove the product entirely when you cannot control the final installation.

    No issues with closed loop systems that I am aware of...

    I remember Paul Pollets relating a story about high temp potable DHW/space heating system failing up in Washington state. The tube was blistering as I remember.

    I have MILES of that stuff out there, and other than having the compression fittings that un did themselves, had no issues.


    There was an error rendering this rich post.

    Same Here

    No issues on hydronic systems. There are several manufacturers whose pex-al-pex is made to the same spec's. We switched to Roth and have interchanged the fittings and pipe with Kitec and had no problems. Just fired up a job with 4500 feet of in slab. Works great.

    Ironman is right.

    The Roth fittings seem to work.  Had no problems with closed systems.  The lawsuit delt with domestic potable water.

    not just DW systems

    I have seen failure on Hydronic systems here in NL, Canada. Insurance companies wont offer home insurance to anyone with the pipe in the home any more. I have only ever seen Kitec installed on one DW system ever in these parts. I have been on several systems where the hydronics had to be re-pipe before sale of a house. And I have witness many leaks on the pipe and fittings. Compression pex-al-pex, crimp pex-al-pex, cheap compression generic. So in my experience this is not a DW only problem.

    Here's a pic of some serious de-zincification on a Kitec piping system to wall convectors using a water heater (open system) as the heat source.
