Question by: Patty E on May 9, 2025, 3:58 PM
Running 316 stainless on a chemical transfer rig and need something that'll handle the connection point without corroding out on me. This got Buna-N seals standard, or do I need to order something different?
Answer by: Customer Support on May 10, 2025, 9:12 PM
Buna-N seals come standard on this socket, so no separate order needed for that. The body itself is 316 stainless steel, which holds up well in chemical processing environments. Flow capacity tops out at 26 gallons per minute, and it's rated down to -40°F, so cold exposure isn't an issue either. It threads in with a 3/4-14 NPTF female connection and uses a ball lock mechanism internally to hold the coupling together during operation.

got a 3/4-14 nptf port on my manifold. is this the right female half to screw in, or am i mixing up sizes
Answer by: Customer Support on Apr 8, 2026, 7:49 AM
You are looking at a 3/4-14 IN NPTF female thread on this socket, and it is the female half with a 3/4 IN body size. If your manifold port is 3/4-14 NPTF, the thread callout matches.
