Legris 3639 10 00 Push-to-connect Tube Fitting 435 Psi

Product Description

The LEGRIS 3639 10 00 is a push-to-connect tube-to-tube fitting constructed from nickel-plated brass. It provides a fast, tool-free connection between two tube ends in pneumatic and fluid-handling lines. Rated to 435 psi maximum working pressure, it suits demanding service in both liquid and gas applications. The FKM o-ring seal supports an operating temperature range of -4 degrees F to 302 degrees F, making it appropriate for environments where standard elastomers would degrade. Plumbers, pipefitters, and industrial maintenance technicians install this fitting when a reliable inline tube connection is needed without the time cost of compression fittings or soldering.

This fitting is suited for residential and light commercial plumbing, pneumatic control lines, and process fluid systems where tube-to-tube inline connections are required. Its push-to-connect design reduces installation time on runs involving both liquid and gas media. The 10 mm outside diameter tube size is common in European-standard pneumatic and fluid systems. Technicians working on compressed air distribution, hydraulic pilot lines, or water service lines will recognize this fitting as a standard inline connector in those configurations.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion
• Nickel-plated brass body resists corrosion in liquid and gas service
• Rated to 435 psi maximum working pressure
• FKM o-ring seal supports operating range from -4 degrees F to 302 degrees F
• Compatible with both liquid and gas media
• Fits 10 mm outside diameter tubing

Compatibility

Designed for use with 10 mm outside diameter tubing in liquid and gas service applications. Suitable as an OEM-style inline tube-to-tube connector in pneumatic and fluid-handling systems requiring push-to-connect fittings.

Installation Notes

Installation is performed by pipefitters, plumbers, or pneumatic system technicians. Before servicing any line, depressurize the system fully and shut off the fluid or gas supply. Ensure tubing ends are cut cleanly and squarely with no burrs before insertion, as debris or uneven cuts can compromise the o-ring seal and cause leaks. Verify the fitting and tubing outside diameter are matched before assembly and confirm the system pressure does not exceed the 435 psi rated maximum.
