Help in identifying a Pex brand

Colin_5

We have a pex pipe that we can't identify the manufacturer. The pipe is labled "7/8 radiant co hydronic heat exchanger tubing". Can't find radiant co on the web.

thanks

7/8\" Tube

Is it this stuff? As far as I know, the 7/8" tubing was not designed to be used for hot water heating. I think the fittings are just barbed fittings with hose clamps. Doesn't inspire a lot of confidence. I would be wary of the connections in that system, particularly if glycol is involved.
