Question by: Lance G on Nov 24, 2025, 8:27 PM
what all can this brass elbow be used on? asking cause i got a mix of pneumatic and hydraulic lines i'm trying to sort out
Answer by: Customer Support on Nov 26, 2025, 6:13 AM
Quite a few systems fall within its range. LP gas, natural gas, refrigeration, power steering, instrumentation, hydraulic, and pneumatic systems are all listed applications for this fitting. The 1/8-27 male NPT side threads into standard pipe fittings, and the 7/16-20 male SAE 45-degree flare end connects to matching flare fittings on the other side. The 45-degree elbow angle gives you some routing flexibility when you're working in a tight spot.
Question by: Dustin C on Feb 2, 2026, 4:37 PM
Will this fitting work okay for hooking up a propane line?
Answer by: Customer Support on Feb 4, 2026, 10:37 AM
This adapter is listed as being suitable for LP and natural gas applications, so it should work for your propane line. Just be sure to check your local codes and regulations for propane installations.
