Question by: Harold W on Jan 15, 2026, 2:49 PM
got a 3/8-18 nptf female port on my line. does this B3T21 plug screw right into that and still give me a quick-connect on the other end?
Answer by: Customer Support on Jan 17, 2026, 7:00 AM
With a 3/8-18 NPTF female port on the plug, it’s meant to mate to a 3/8 NPTF male thread on your equipment. The opposite end is the push-to-connect male half, using a ball lock style for quick connect and disconnect without special tools.
