Product Questions & Answers

What size tubing does this fitting work with? Seems like I'm always getting the wrong size.

Question by: Bonnie J on Apr 3, 2026, 10:55 AM

This fitting is designed for tubing with a 0.50 inch OD (Outer Diameter). Making sure you match that spec will give you a good, solid connection.

trying to hook up 1/2" tubing to a 3/8 nptf port, is this the right fitting?

Question by: Ray P on Oct 2, 2025, 11:09 AM

For that setup, it matches a 0.50 inch tube outside diameter on the push-to-connect side and a 3/8 NPTF male thread on the other end, in a straight male connector style.
