threading directly in PVC pipe fitting
threading directly in PVC pipe fitting
(OP)
Quick question here. Is there any regulation (ASTM/ANSI) or documentation that confirm that you can tap threads directly into a PVC sch 80 PVC pipe fitting. In my case it's a 1/4" NPT into a 1 1/2" sch 80 elbow and "T".
Thanks.
Thanks.

We will design everything from now on using only S.I. units ... except for the pipe diameter. Unk. British engineer

In this regard I have also not seen a great deal of detailed supportive research involving various modal testing readily available concerning capabilities of directly threaded taps/joints involving plastic components or piping material mixes involving plastics; however, I am aware of the quite detailed comparative testing published by the Ductile Iron Pipe Research Association at http://www.dipra.org/pdf/DIPvsPVCTapping.pdf (note however these taps are a little larger than those with which you are reportedly dealing). Some other reports appear some less flattering, e.g. that of "Big Gus", OP on the thread I've noticed at ht
Everyone have a good weekend :>)
