Question by: Todd F on Nov 28, 2025, 7:45 PM
Will this adapter work alright for hooking up a power steering system?
Answer by: Customer Support on Nov 30, 2025, 6:42 AM
This brass adapter is suitable for power steering systems, as well as hydraulic and pneumatic setups. It's also used in LP and natural gas applications, plus refrigeration systems.
Question by: Janet S on Dec 4, 2025, 11:17 AM
got a refrigeration line with a 7/16-20 SAE 45 flare on the equipment side and need to tie into a 1/4 NPT port on my gauge manifold. this fitting work for that?
Answer by: Customer Support on Dec 5, 2025, 3:54 PM
That's the kind of connection this adapter handles. One end is a 7/16-20 male SAE 45 degree flare and the other is a 1/4-18 male NPT, so it bridges those two thread types in a straight configuration. Refrigeration is listed as one of the intended applications, so you're in the right territory with that use case.
