Frequently Asked Questions
Which end threads and which end cements?
The male NPT end (2-1/2 - 8) threads into a female threaded port; the slip socket end solvent-welds onto 2-1/2 in. Schedule 80 PVC pipe.
What sealant is recommended for the large thread?
Use PTFE tape or PVC-compatible pipe dope. On larger plastic threads, hand-tighten then add only one to two turns to avoid stressing the fitting.
Will the socket take Schedule 40 pipe?
Yes. 2-1/2 in. Schedule 40 and 80 pipe share the same outside diameter, so both fit the socket.
What is the temperature rating?
Approximately 140°F; de-rate working pressure as service temperature rises above 73°F.
