Legris 3175 53 11 Push-to-connect Tube Fitting 1/8 in

Product Description

The LEGRIS 3175 53 11 is a push-to-connect tube fitting designed to create a fast, tool-free connection between 1/8 inch OD tubing and a 1/8 inch male NPT port. The body is constructed from nickel-plated brass, offering corrosion resistance suitable for a range of pneumatic and fluid-handling applications. It is rated to 290 psi maximum working pressure and handles temperatures from -4 degrees F to 175 degrees F. Plumbers, HVAC technicians, and industrial maintenance professionals install this style of connector where a reliable, leak-resistant push-in connection is needed without soldering or compression tooling.

This fitting is suited for use in low-to-medium pressure pneumatic lines, instrument air systems, and light-duty fluid control circuits found in both residential and light commercial equipment. It threads directly into any standard NPT-tapped port and accepts 1/8 inch OD tubing with a simple push-in insertion. Typical install scenarios include control panel pneumatics, HVAC controls with tubing runs, and industrial equipment plumbing where quick disassembly and reassembly are advantages. The nickel-plated finish helps resist oxidation in environments with moderate humidity or mild chemical exposure.

Compatibility

Designed as an OEM-style push-to-connect connector fitting for use with 1/8 inch OD tubing and equipment featuring 1/8 inch NPT-tapped ports in pneumatic and fluid-handling systems.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or industrial mechanics working on pneumatic or low-pressure fluid lines. Before installing, depressurize the system completely and verify that the receiving NPT port is clean and undamaged. Apply appropriate thread sealant to the male NPT threads per local plumbing or mechanical codes before threading into the port. Insert tubing fully until it bottoms out in the fitting body to ensure a secure, leak-free connection.
