Pro-source 2557518465PRO Push-to-connect Tube Fitting 5pk

Product Description

The PRO-SOURCE 2557518465PRO is a push-to-connect tube fitting with a female NPT port, designed for inline tube-to-tube connections with a branch female thread. It accepts 1/8 inch OD tubing on both tube ends and uses a 1/4 inch NPTF female thread connection. The body is nickel-plated brass, rated to 250 psi maximum working pressure with a temperature range of 0 to 160 degrees F. An Buna O-ring provides the primary seal. This fitting is used in compressed air and water systems and is installed by plumbers, HVAC technicians, and pipefitters working with small-bore pneumatic or fluid control lines.

This fitting is suited for residential and light commercial applications where 1/8 inch OD tubing must connect to a female NPT threaded port while continuing a tube run. Typical scenarios include instrument air lines, condensate management tubing, and low-pressure water distribution sub-circuits. The push-to-connect mechanism allows tool-free tube insertion, making it practical for panel-mount and tight-clearance installs. Each order ships as a pack of 5 fittings.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off the air supply or close the water isolation valve and relieve system pressure before removing or installing any fitting. Ensure tubing is cut square and deburred before inserting into the push-to-connect port. Verify NPTF thread engagement meets applicable IPC or system requirements before restoring pressure.
