Radiantec Smartwall tubing

Jeff Perry_3

Lucky me has a job with 3 zones of 5/8 Radiantec Smartwall tubing. Their idea of a manifold is their fittings, ball valves and a copper header. No flow meters. I wanted to install a standard manifold like Rehau or something. Their tubing is odd sized and no matter what I have tried no R20 or compression fitting will allow me to transition to a standard 5/8 PEX fitting to let me use my manifold.

Anyone else ever have to deal with this?

"Because of its thinner wall, this tubing may or may not be accepted by local codes." that comes straight from their website, they made cheap proprietary junk and you got stuck with it. Probably have to use their specific fittings.

Isn't it best to just rip out all of the Radiant-wreck junk and install proper radiant heating components?

Is there any listing on the tube to give you an idea of what fitting will match?

If you know the OD, a metric R-20 may work

That's a shame.  I never saw any reason to switch from the original, Wirsbo/Uponor...why? To save a few bucks?  Used Slant Fin a few times when that's what was spec'd for job.  No problems with the tubing, but wasn't crazy about the Manifolds and lawn sprinkler clamps. They had a class action lawsuit against them when they failed and they suddenly dropped the whole radiant line..  That was the beginning of the end of an otherwise great,, Local, Long Island Manufacturer.  Mad Dog
