Pro-source 2557514465PRO Push-to-connect Tube Fitting 5 Pack

Product Description

The PRO-SOURCE 2557514465PRO is a push-to-connect tube fitting with a tube-x-FNPT-x-tube configuration, providing an inline connection point between two push-to-connect tube runs and a female NPT branch or port. The body is nickel-plated brass, rated to 250 psi working pressure. The fitting accepts 1/4-inch OD tubing on both tube ports and a 1/4-inch NPTF female thread on the center port. The Buna-N O-ring collet seal provides a reliable, tool-free tube connection. Licensed plumbers, pipefitters, and HVAC technicians install this fitting on compressed air distribution lines and water service tubing in both residential and light commercial applications.

This fitting is suited for use on compressed air supply lines and water distribution tubing where a quick-connect tube fitting is preferred over compression or flare connections. The push-to-connect design allows fast field assembly and disassembly without specialized tooling. The NPTF female port accepts a male NPT instrument, valve, or manifold fitting, making this configuration useful for tee-style branch connections or sensor port hookups on air and water lines. Sold in a package of five units.

Key Features

• Push-to-connect tube ports accept 1/4-inch OD tubing without tools for fast, repeatable assembly
• Nickel-plated brass body resists corrosion on air and water service
• 250 psi pressure rating suitable for compressed air distribution and low-pressure water lines
• 1/4-inch NPTF female thread port compatible with standard male NPT fittings and instrumentation
• Buna-N O-ring collet seal maintains a leak-free connection across normal service temperature ranges
• Package quantity of five units reduces per-unit cost on multi-fitting installations

Compatibility

Designed for use with compressed air and water tubing systems using 1/4-inch OD tubing and standard 1/4-inch male NPT threaded ports. Suitable for OEM and field service applications in HVAC, pneumatic controls, and plumbing.

Installation Notes

Shut off and depressurize the line before installing or removing any push-to-connect fitting. Ensure tube ends are cut square, deburred, and fully seated past the collet before pressurizing. NPTF threads should be assembled to the appropriate thread engagement depth per IPC or manufacturer guidance; use thread sealant tape or compound on male NPT threads as required by local code. Depressurize the line completely before releasing a tube from the collet by pressing the release collar inward.
