Product Questions & Answers

got a 1/4 inch air brake tube and need to swing into a tight spot, is this the right elbow to go from tube to 1/4 npt?

Question by: Jimmy P on Aug 4, 2025, 1:22 PM

For a 1/4 inch tube OD going into a 1/4-18 male NPT port with a 90 degree turn, this fitting matches that setup. It is a push to connect style for 0.25 inch tube OD on one end and 1/4-18 male NPT on the other, with an EP O-ring to help seal the NPT side.

What kind of temperatures can this elbow fitting handle?

Question by: Neal B on Sep 23, 2025, 11:01 AM

This fitting is made to hold up in temperatures from -40F to +200F.

fitting's rated up to 150 psi, but does it hold up alright under vibration or is that gonna be a problem on a working truck?

Question by: Hank B on Feb 14, 2026, 8:06 AM

Moderate vibration is well within what this fitting handles. It carries DOT FMVSS 571.106 and SAE J1131 certifications, both of which are air brake system performance standards that specifically account for real-world operating conditions. The EP O-ring forms a secure seal at the tube connection, so you're not relying on compression alone to keep things tight when things get shaking.
