Burnham heat pex from 2001

Does anyone have experience with heat pex branded Burnham? A rep from US boiler I spoke with thought it may be a re - branded Wirsbo product. I'd like to confirm the tubing is expandable before I try to repair a leaking joint......

It was Hewing pex from Germany.

Thank you, Bob. I emailed that company for some information.

looks like thy offer pex C, at least now.

I would only expand the A pex. Although some B pex manufacturers are promoting expending B. Some tests I have seen are not so conclusive about expanding B pex

I heard back from Hewing in Germany; they say the tubing is not theirs. I wish someone from US Boiler would chime in on this like Energy Kinetics, Taco, and other manufacturers do. ....

Here is what Burnham claimed when it was introduced?

Thanks again, Bob. I forwarded the article to the person who contacted me from Hewing.

@MikeL_2
I remember those days from when I was with RTI (also an Uponor company), the Burnham pex from back then was from Hewing and Hewing was (at least back then) associated with Uponor.

However, Hewing only made a pex-c in those days so I would not expand it.

You should be able to use any other compression fitting.

My thoughts exactly. Why not simply use the copper crush ring system to be safe? I use them on PEX-A,B ,and C. Dont get me wrong, I expand wirsbo/uponor and Mr.PeX too, but sometimes the crush rings (not the side cinches) work great.

If you do a fitting requiring crimp rings, I like the stainless collars best, copper rings next. I think the pinch style cinch rings are a crappy look, sharp and often the pex turns easily after pinched.

I think Sioux Chief offers all styles of pex fittings and rings now, expansion, copper, stainless crimp.
