Pro-source 2555514865PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555514865PRO is a push-to-connect tube fitting designed to join 1/4 inch OD tubing to a 1/8 inch universal thread port. The body is nickel-plated brass with a Buna-N O-ring seal and is rated to 250 psi. Installation requires no tools on the tube side — tubing inserts directly and locks in place, reducing labor time during assembly or service. HVAC technicians, plumbers, and industrial service techs use this type of fitting on control lines, pneumatic circuits, and low-pressure fluid systems where a fast, reliable connection is needed.

This fitting suits residential and light commercial applications where 1/4 inch OD tubing terminates at a threaded port or manifold. Typical uses include HVAC condensate or refrigerant sensing lines, pneumatic control tubing, and general fluid transfer lines that require a secure push-to-connect transition to a universal thread port. Each package contains 5 fittings, making it practical to stock multiples for recurring service calls or panel assembly work.

Key Features

• Push-to-connect design accepts 1/4 inch OD tubing without tools on the tube side
• 1/8 inch universal thread port for broad compatibility with standard threaded ports
• Nickel-plated brass construction resists corrosion in wet or humid environments
• Buna-N O-ring provides a reliable seal against fluid and air leakage
• Rated to 250 psi for use in low-to-medium pressure pneumatic and fluid systems
• Sold in packs of 5, suitable for stocking on service vehicles or in parts inventory

Compatibility

Designed as an OEM-style replacement or new-installation fitting for systems using 1/4 inch OD tubing terminated at a 1/8 inch universal thread port, including pneumatic control circuits and HVAC sensing line assemblies.

Installation Notes

Depressurize and drain the system completely before removing or installing any fittings. Verify that tubing OD is clean, free of burrs, and cut square before inserting into the push-to-connect end. Thread the universal thread side hand-tight before applying tool torque; do not overtighten, as brass threads can be damaged. Follow applicable codes such as ASME B31.1 or the system manufacturer's guidelines for fluid and pneumatic line connections.
