got a 3/8 inch air line i need to split into two directions, this union tee gonna work for that?

For a 3/8 inch OD tube, yes, this is the right fitting. It's a union tee configuration, so it connects three lengths of tubing at a single junction, which is exactly what you need when you're branching one line into two. Brass construction holds up well in standard air line setups, and the push-to-connect design means you're not threading anything or reaching for extra tools to get it seated.

What size tubing does this fitting work with? Just want to make sure it's what I need for my setup.

Answer by: Customer Support on Jun 9, 2025, 7:01 PM

It's designed for tubing with a 0.375 inch (or 3/8 inch) outer diameter.

got 3/8 tubing in my air line setup, is this the tee that’ll fit it?

Answer by: Customer Support on Dec 18, 2025, 6:32 AM

The key spec is the tube outside diameter. This union tee is made for 0.375 inch tube OD, which is the same as 3/8 inch tubing.
