Got a metric port on a piece of equipment and need to tie in an NPT line. This the right kind of fitting to bridge that gap?

Question by: Frank G on Dec 6, 2025, 9:27 AM

For exactly that situation, yeah, this adapter is what you want. One end is 1/4 NPT female, the other is M16 x 1.5 female metric, so it handles that crossover between the two thread standards without needing any additional adapters in between. It's a fixed configuration, meaning it won't rotate once installed, but if your lines are already routed and you just need a solid, non-moving connection, that's not an issue at all.

got a hose end that’s 1/4 NPT female and the machine port is metric, M16 x 1.5. is this the right little adapter to tie those together?

Question by: Lance H on Sep 3, 2025, 10:58 AM

For mixed-thread hookups, this adapter is meant to bridge a 1/4 NPT female connection on one side to an M16 x 1.5 female metric connection on the other, so it fits that NPT to metric situation.

Will this here adapter hold up alright if I'm usin' it on somethin' that vibrates some?

Question by: Jerry S on Dec 5, 2025, 4:55 PM

This Adaptall fitting is best used in applications where you need a secure, rigid connection, since it's a fixed, non-swivel adapter.
