Legris 3140 10 12 Union Y Tube Fitting 10mm X 12mm

Product Description

The LEGRIS 3140 10 12 is a push-to-connect union Y tube fitting designed for tube-to-tube connections in pneumatic and fluid handling systems. Constructed from glass-reinforced nylon with a nitrile O-ring seal, it accepts tube outside diameters of 10 mm and 12 mm in a Y-branch configuration. The fitting handles up to 290 psi working pressure and carries a vacuum rating of 28 in-Hg. Installation requires no tools beyond hand pressure to seat the tubes — a collar release disengages the tube for removal. Licensed trades and industrial maintenance technicians working with compressed air or compatible fluid lines are the primary installers.

This fitting is suited for light industrial, pneumatic control, and process plumbing applications where a Y-branch tube junction is needed. The push-to-connect design allows fast field assembly and disassembly without fittings wrenches or thread sealant. Its glass-reinforced nylon body resists moderate chemical exposure and keeps weight low in panel or manifold assemblies. Typical install scenarios include pneumatic automation panels, HVAC pneumatic controls, and compressed air distribution runs where tube branching is required.

Key Features

• Push-to-connect design for tool-free tube insertion and collar-release removal
• Accepts 10 mm and 12 mm outside diameter tubing in a Y-branch configuration
• Glass-reinforced nylon body for lightweight, moderate chemical resistance
• Nitrile O-ring seal compatible with air and many common pneumatic fluids
• Rated to 290 psi working pressure with a vacuum rating of 28 in-Hg

Compatibility

Designed as an OEM-style push-to-connect replacement fitting for pneumatic tube systems using 10 mm and 12 mm outside diameter tubing.

Installation Notes

Installation is performed by pneumatic system technicians or industrial maintenance trades. Depressurize and isolate the pneumatic line completely before removing or installing any fitting. Confirm tube cut ends are clean, square, and free of burrs before inserting into the push-to-connect collet — deformed tube ends can compromise the seal. Follow applicable compressed air system codes and the equipment manufacturer guidelines for maximum operating pressure and fluid compatibility.
