Parker W171PLP-5-2 Male Run Tee 5/16in Od 1/8in Nptf

Product Description

The PARKER W171PLP-5-2 is a push-to-connect male run tee tube fitting designed for quick, tool-free tube connections in pneumatic and fluid-transfer systems. Constructed from nickel-plated brass with a nitrile O-ring, it handles a maximum working pressure of 300 psi across a temperature range of 0 to 200 degrees F. The fitting accepts 5/16 inch OD tubing on the run ports and connects to a 1/8 inch NPTF male thread port, making it suitable for inline branching applications. The black actuator button is made from a flame-resistant material rated to UL94 V-0. HVAC technicians, plumbers, and pneumatic system installers use this fitting where a compact inline tee connection is required without soldering or flaring.

This fitting is suited for light commercial and residential pneumatic, instrumentation, and fluid-control applications. Its push-to-connect design allows rapid tube insertion and release, reducing installation time in tight spaces. The NPTF thread form provides a pressure-tight mechanical seal on the male NPT port, making it compatible with standard pipe thread assemblies. Typical install scenarios include instrument tubing runs, control-line branching in HVAC equipment, and low-pressure fluid distribution panels where 5/16 inch OD tubing is routed to a threaded component or manifold.

Key Features

• Nickel-plated brass body provides corrosion resistance in moderate-duty environments
• Nitrile O-ring seals rated for working pressures up to 300 psi
• Operating temperature range of 0 to 200 degrees F
• UL94 V-0 flame-resistant black button material
• NPTF male thread delivers a pressure-tight connection on the branch port

Compatibility

Designed as an OEM-style push-to-connect fitting for systems using 5/16 inch OD tubing with a 1/8 inch NPTF male thread interface. No specific model compatibility was provided by the manufacturer for this SKU.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic or fluid-control systems. De-pressurize the system fully before installing or removing any fitting. Ensure tubing ends are cut square, deburred, and clean before inserting into the push-to-connect ports. Thread engagement on the NPTF port should comply with applicable piping codes; do not overtighten, as the NPTF taper thread is designed to seal on thread engagement without requiring excessive torque.
