Legris 3102 10 12 Push-to-connect Union Fitting 10mm

Product Description

The LEGRIS 3102 10 12 is a push-to-connect union tube fitting designed for tube-to-tube connections in pneumatic and fluid-handling systems. Constructed from glass-reinforced nylon with a nitrile O-ring, it provides a lightweight yet durable straight union that requires no tools to assemble. The fitting accepts tubing with a 10mm outside diameter and is rated to 290 psi, with a vacuum rating of 28 in-Hg. It is suited for compressed air lines, pneumatic control circuits, and low-pressure fluid distribution in industrial and mechanical systems. Licensed plumbers, HVAC technicians, and industrial maintenance technicians are the typical installers.

This fitting is used in applications where a quick, reliable tube-to-tube inline union is needed without threading or soldering. The push-to-connect design allows fast field assembly and disassembly, making it practical for control panel plumbing, pneumatic actuator lines, and instrumentation tubing runs. It performs in both positive-pressure and moderate vacuum service, covering a broad range of light industrial and mechanical applications. The glass-reinforced nylon body resists moisture and common industrial fluids, adding service life in demanding environments.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Glass-reinforced nylon body for strength and chemical resistance
• Nitrile O-ring sealing for compatibility with air, water, and common industrial fluids
• 290 psi pressure rating supports standard pneumatic and fluid-handling service
• 28 in-Hg vacuum rating enables use in suction-side applications
• Accepts 10mm OD tubing for metric pneumatic plumbing systems

Compatibility

Designed as an OEM-style replacement or new-installation union fitting for systems using 10mm outside diameter push-to-connect tubing in pneumatic and fluid-handling circuits.

Installation Notes

Installation is typically performed by HVAC technicians, industrial maintenance mechanics, or licensed plumbers working on pneumatic or fluid-distribution systems. Depressurize and isolate the line completely before disconnecting or inserting tubing. Ensure tubing ends are cut square and free of burrs before insertion to achieve a proper seal. Verify system pressure and fluid compatibility with the fitting materials before returning the line to service.
