got a -06 line and need a stainless quick connect plug, is this the male half with 3/8-18 female nptf threads?

Question by: Judy C on Nov 1, 2025, 8:17 PM

This one is the HK Series Industrial Interchange Series B male half in -06 size, and the threaded end is 3/8-18 female NPTF. The other end is a male push-to-connect style for the mating quick disconnect.

Got a setup running 3/8 female NPT ports, this plug gonna thread right in without adapters or anything extra?

Question by: Rod M on Apr 14, 2025, 8:10 AM

threads straight in. The female end on this coupling is 3/8-18 NPTF, so it mates directly with a 3/8 female NPT port on your equipment. No adapters needed for that configuration. Just make sure your mating half is a Series B Industrial Interchange male socket, since that's what this plug is built to connect with.
