Brass Push Tube Fitting, 0.25 Inch Tube OD Run & Branch To 3/8 NPT Male Swivel Run, Tee

Description & Features

Designed for 1/4 inch tube OD connections, this Numatics Brass Push Tube Fitting, 0.25 Inch Tube OD Run & Branch To 3/8 NPT Male Swivel Run, Tee provides a reliable three-way connection point in pneumatic tube systems. The tee configuration supports both run and branch connections simultaneously, with a 3/8 NPT male swivel on the run port to simplify alignment during installation without requiring tube or assembly rotation.

Brass construction offers good corrosion resistance and durability in typical industrial pneumatic environments. The push-to-connect design allows for tool-free tube insertion and removal, making it well suited for panel assemblies, manifold builds, and instrumentation lines where quick reconfiguration may be needed. Key dimensions include an L of 0.74, L1 of 1.181, and L2 of 0.512, with a D of 0.472 and D1 of 0.236.

Question by: Denise J on Jun 12, 2025, 1:32 PM

Will this fitting hold up okay in a greasy environment, or should I look at something else?

Answer by: Customer Support on Jun 14, 2025, 6:19 AM

Brass offers decent corrosion resistance for typical industrial environments where pneumatic systems are common, so it should do fine with incidental grease. For constant or heavy exposure, though, you might want to explore a more specialized fitting.

trying to hook up 1/4 inch tubing, but the threaded side is 3/8 NPT right?

Answer by: Customer Support on Jul 4, 2025, 11:01 AM

The push-to-connect ports are for 1/4 inch tube OD on the run and the branch, and the run port has a 3/8 NPT male swivel thread.

Question by: Shane W on Jun 10, 2025, 10:20 AM

Got a panel build with 1/4 inch tubing running into a 3/8 NPT port, would this tee handle that transition without needing extra adapters?

Answer by: Customer Support on Jun 12, 2025, 7:49 AM

That's exactly the setup this fitting is built for. The two push-to-connect ports take 1/4 inch OD tube on both the run and branch sides, and the swivel run port threads directly into a 3/8 NPT male connection. The swivel lets you get the fitting seated in the port first and then rotate it into position without twisting the tubing or disturbing anything already assembled. No extra adapters needed for that combination.
