Legris 3626 08 00 Push-to-connect Plug 5/16 in Od

Product Description

The LEGRIS 3626 08 00 is a push-to-connect plug-style tube fitting designed to seal off an open tube end quickly and securely. Constructed from nickel-plated brass with an FKM O-ring, it accepts tubing with a 5/16 inch outside diameter and holds a maximum working pressure of 435 psi. With an overall length of approximately 1.3 inches (33 mm), the fitting is compact and suited for tight installations. Licensed plumbers, pneumatic system technicians, and fluid-handling specialists install this type of plug when capping an unused port or temporarily isolating a line without tools or thread sealant.

This plug fitting is rated for use with both liquid and gas media, covering a working temperature range of -4 degrees F to 302 degrees F. That range makes it appropriate for a broad set of industrial, HVAC, and pneumatic plumbing applications where a reliable, tool-free seal on a 5/16 inch OD tube is required. It carries multiple compliance certifications including RoHS, ATEX, PED, REACH, ISO 14743, UL94 V-0, and FDA 21CFR, making it suitable for installations with strict regulatory or material-safety requirements.

Key Features

Compatibility

Designed as an OEM-style plug fitting for systems using 5/16 inch outside diameter push-to-connect tubing in liquid or gas service applications.

Installation Notes

This fitting is installed by licensed plumbers or pneumatic system technicians. Before installation, depressurize and bleed the line completely to zero pressure. Insert the tube squarely to full depth to ensure the internal collet and O-ring engage correctly. To release, depress the release collar before withdrawing the tube to avoid damage to the fitting seat.
