Can anybody point me in the right direction to research this tubing? Mid to late 80s, rubber tubing on a radiant floor heat loop, no markings on any of the visible portions, way too flexible to have an oxygen barrier.
My research has brought up a few different brands from several different manufacturers from Watts to Goodyear. I would think that if it was made for the application it would have some sort of marking on it.
My concern is that this is a hay farm and it my not be a listed material, but rather an EPDM or LDHP ag product.
Thanks in advance...
