I have some tubing that is from 1984ish. The only info I can get directly off of the tube is: 3200 upc, sdr11, 180deg., 100psi, B1378, IAPMO IS 22-8-W8, 1/2"otc, 5/8"od, C 07-18-84.

The tubing is a medium grey color and is used for infloor heating in concrete.

What is it? Is it an oxygen barrier tubing? any info would be appreciated.

Thanks,

Bob

    Sounds like Poly Suitylene

    er I meant Poly Butylene.



    It came in both barrier and non barrier tube, and if you can't identify it by manufacturer, you'd best treat it as non barrier tube.
