Legris 3180 12 00 Push-to-connect Tube Plug 12mm

Product Description

The LEGRIS 3180 12 00 is a push-to-connect tube plug fitting designed to seal off open 12mm outside-diameter pneumatic or fluid lines without tools. Constructed from glass-reinforced nylon, this plug delivers a pressure rating of 290 psi and a vacuum rating of 28 inches Hg, making it suitable for both pressurized and vacuum circuit termination. The nitrile o-ring provides a reliable seal compatible with common hydraulic fluids, oils, and compressed air. Plumbers, pneumatic system technicians, and industrial maintenance professionals install this fitting during system modifications, testing, or line isolation.

This plug is used to cap unused or open tube ports in pneumatic control panels, compressed air distribution systems, and fluid transfer lines. Its push-to-connect design allows quick, tool-free installation on 12mm OD tubing in tight or hard-to-reach spaces. Typical applications include capping unused manifold ports, sealing off branch lines during system reconfiguration, and temporary or permanent line termination in light industrial and commercial environments.

Key Features

• Push-to-connect design allows tool-free installation on 12mm OD tubing
• Glass-reinforced nylon body rated to 290 psi operating pressure
• Vacuum rated to 28 inches Hg for both pressure and vacuum circuit use
• Nitrile o-ring seal compatible with compressed air, oils, and common hydraulic fluids
• Compact plug form factor for capping open ports or unused line ends

Compatibility

Designed as a push-to-connect plug for 12mm outside-diameter tubing in pneumatic and fluid transfer systems. Verify tube OD and system pressure before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid system procedures. Depressurize and de-energize the system completely before inserting or removing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely and that the tube end is free of burrs before insertion. Confirm the system operating pressure and vacuum rating do not exceed the limits of this fitting.
