Legris 3188 60 00 Push-to-connect Plug 3/8 Inch Od

Product Description

The LEGRIS 3188 60 00 is a push-to-connect tube plug fitting designed to seal off open tubing ends in pneumatic and fluid control systems. Built from glass-reinforced nylon, it handles working pressures up to 290 psi and carries a vacuum rating of 28 in-Hg. The nitrile O-ring provides a reliable seal against common gases and fluids encountered in compressed air and light fluid lines. This fitting accepts tubing with a 3/8 inch outside diameter and requires no tools for installation, making it a practical solution for technicians capping unused ports or isolating circuit branches during service or system modifications.

This plug fitting is suited for residential and light commercial pneumatic plumbing and fluid distribution applications. It is commonly installed when capping branch lines, blocking unused manifold ports, or temporarily isolating a circuit segment during diagnostics. The push-to-connect design makes it a fast, repeatable option in control panel builds and compressed air distribution systems where frequent access or reconfiguration is expected.

Key Features

• Push-to-connect design requires no tools or thread sealant for installation
• Glass-reinforced nylon body rated to 290 psi working pressure
• Nitrile O-ring seal compatible with compressed air and common light fluids
• Vacuum rated to 28 in-Hg for use in both pressure and vacuum circuits
• Accepts 3/8 inch OD tubing for a secure, leak-free cap

Compatibility

Designed as an OEM-style push-to-connect plug for pneumatic and fluid control tubing with a 3/8 inch outside diameter. Consult system documentation to confirm fitting series compatibility before installation.

Installation Notes

Depressurize and de-energize the system completely before removing or installing any fittings. Push-to-connect fittings seat when tubing is inserted firmly until it bottoms out in the collet. To release, depress the collet ring evenly while pulling the tubing straight back. Inspect tubing ends for burrs or ovality before insertion, as deformed tubing ends are a common cause of seal failure.
