Parker W171PLP-5-4 Male Run Tee 5/16in Od 1/4in Nptf

Product Description

The PARKER W171PLP-5-4 is a push-to-connect male run tee tube fitting designed for pneumatic and fluid distribution lines where a branch takeoff with a male NPT port is needed in a single inline fitting. Constructed from nickel-plated brass with a nitrile O-ring, it handles working pressures up to 300 psi and temperatures from 0 degrees F to 200 degrees F. The fitting accepts 5/16-inch OD tubing on the run ports via tool-free push-to-connect engagement and connects to a 1/4-inch NPTF male thread on the branch. The release button is made from black, flame-resistant material rated UL94 V-0, suitable for applications requiring fire-resistance compliance.

This fitting is commonly used in HVAC control lines, refrigeration ancillary circuits, pneumatic controls, and light industrial fluid systems where a compact inline tee with an NPT branch is required. The push-to-connect tube ports allow fast, repeatable field connections without ferrules or compression tooling, making it practical for service technicians working in tight equipment cabinets or control panels. Its nickel-plated brass construction resists corrosion in moderate-humidity environments.

Key Features

• Push-to-connect tube ports accept 5/16-inch OD tubing with no tooling required

• Nickel-plated brass body for corrosion resistance
• 300 psi maximum working pressure
• Operating temperature range: 0 degrees F to 200 degrees F
• UL94 V-0 rated flame-resistant release button
• Nitrile O-ring seal compatible with common pneumatic and fluid media

Compatibility

Designed as an OEM-style replacement or field-service fitting for pneumatic and fluid distribution systems using 5/16-inch OD tubing and 1/4-inch NPTF male branch connections.

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or pipefitter. Depressurize and isolate the line completely before disconnecting or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely and deburred before insertion into the push-to-connect port to achieve a proper seal. Verify NPTF thread engagement meets applicable system requirements before returning the circuit to service.
