Legris 3175 60 14 Push-to-connect Connector 3/8 Od

Product Description

The LEGRIS 3175 60 14 is a push-to-connect tube-to-male NPT connector fitting designed for quick, tool-free tube connections in pneumatic and fluid-handling systems. Constructed from nickel-plated brass, it accepts 3/8 inch OD tubing on one end and threads directly into a 1/4 inch MNPT port on the other. The fitting is rated to 290 psi maximum working pressure and handles temperatures from -4 degrees F to 175 degrees F, making it suitable for a wide range of compressed air, water, and compatible fluid applications. Plumbers, pipefitters, and pneumatic system technicians install this fitting where a fast, reliable tube termination at a threaded port is required.

This connector is used in residential and light commercial pneumatic lines, fluid distribution manifolds, and control system plumbing where 3/8 inch OD tubing must terminate at a 1/4 inch MNPT threaded fitting. Typical install scenarios include compressed air distribution panels, HVAC pneumatic control tubing, water treatment equipment, and similar systems requiring a leak-tight push-to-connect interface at a male NPT port. The push-to-connect mechanism allows tubing to be inserted and locked without additional tools or ferrules, speeding up assembly and service work.

Key Features

• Push-to-connect design allows tool-free tube insertion and secure locking
• Nickel-plated brass construction resists corrosion and withstands moderate pressure cycling
• Rated to 290 psi maximum working pressure
• Operating temperature range of -4 degrees F to 175 degrees F suits most HVAC and pneumatic environments
• 1/4 inch MNPT thread for direct installation into standard NPT-tapped ports
• Accepts 3/8 inch OD tubing without ferrules or compression sleeves

Compatibility

Designed as an OEM-style push-to-connect connector for pneumatic and fluid-handling systems using 3/8 inch OD tubing with 1/4 inch MNPT threaded port connections.

Installation Notes

Installation is performed by plumbers, pipefitters, or qualified HVAC technicians. Depressurize and isolate the system before removing or installing any fitting. Ensure the male NPT threads are clean and apply thread sealant tape or compound as required by applicable plumbing codes. Tubing must be cut square and fully inserted into the push-to-connect collet until it seats completely to ensure a leak-free connection.
