Product Questions & Answers

What size tubing does this elbow fit? Just want to make sure I'm ordering the right thing.
Question by: Roger B on Feb 23, 2026, 6:45 PM
This elbow fitting is made for 0.31 inch (that's about 5/16") OD tubing.

Got a 5/16 tube line coming off a small hydraulic valve block and need to route it around a corner with a 1/8 NPT male port, this fitting do that job?
Question by: Floyd C on Nov 13, 2025, 6:45 PM
That's exactly the application this fitting handles. The tube side accepts 5/16 inch OD tubing and the threaded end is 1/8-27 male NPT, so it connects directly into a female NPT port on your valve block. The 90 degree elbow lets you redirect the line cleanly without bending the tube, which is especially handy in tight quarters around valve banks or manifolds.
