Product Questions & Answers (2)

Question by: Kirk P on Jun 9, 2025, 10:00 AM
does this socket work with a standard 3/8 NPTF port or do I need some kind of adapter to hook it up?
Answer by: Customer Support on Jun 11, 2025, 7:32 AM
Straight connection, no adapter needed. The 3S21 has a 3/8-18 NPTF female thread on the port end, so it threads directly onto any standard 3/8-18 NPTF male fitting. The body is brass and the internal lock is ball-style, so once it's threaded in and torqued down you're good to go.

i’m trying to swap out an old Hansen socket, is this 3S21 the female half with 3/8-18 NPTF threads?
Answer by: Customer Support on Aug 3, 2025, 11:06 AM
The 3S21 is the female half (socket) and it has a 3/8-18 NPTF female pipe thread connection, with a 3/8 inch body size.
