This adapter is exactly what you'd use to connect a male G3/8-19 BSPP fitting to a female 1/4-18 NPT fitting. It's a straight adapter, so it'll keep everything aligned directly.

Got a line running G3/8 BSPP on one end and need to tie into a 1/4 NPT female port, this the right piece for that?

Answer by: Customer Support on Aug 19, 2025, 6:02 AM

That's what this adapter is built for. The male end is G3/8-19 BSPP and the female end accepts 1/4-18 NPT, so you're connecting in the right direction. It's a straight configuration, no angle, no offset. Adaptall makes these to pretty tight tolerances, so you shouldn't need thread tape or sealant to get a solid connection.
