Legris 3175 62 22 Brass Push-to-Connect x MNPT Trap

Brass Push-to-Connect Fitting

This Legris 3175 62 22 fitting connects 1/2 inch outer-diameter tubing to a 1/2 inch MNPT port using a push-to-connect design. The brass body is rated for vacuum applications and includes pre-applied thread sealant on the MNPT side. It suits installers who need a quick, tool-free joint in pneumatic or low-pressure fluid lines. Buyers who require a compression or flare connection will need a different fitting style.

Simple Push Installation

Push the tubing into the fitting until it seats; the internal collet grips automatically and the pre-applied sealant handles the MNPT threads. No wrenches or separate thread tape are required for the tube end. The most common error is inserting the tube at an angle or stopping short of the internal stop, which prevents a full seal and can cause leaks under the 290 psi rating.

Maximum 290 psi at 175 °F

The fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees Fahrenheit. These two limits determine whether the part matches the system design. If the circuit exceeds either value, this fitting is not suitable.
