Parker KP23589 Male Run Tee 5/16 in Od 3/8 Bspt Nylon 290 Psi

Product Description

The PARKER KP23589 is a push-to-connect male run tee tube fitting designed for quick, tool-free connections in pneumatic and fluid-transfer plumbing systems. Constructed from nylon, it accommodates tubing with a 5/16-inch outside diameter and features a 3/8-inch BSPT male thread on the branch port. The fitting is rated to 290 psi, making it suitable for moderate-pressure pneumatic lines. Its push-to-connect design allows tubing to be inserted and locked without ferrules, compression nuts, or additional fittings. Licensed plumbers and HVAC technicians working on instrument air, control lines, or light fluid systems install this type of fitting as part of threaded manifold assemblies or branch-line connections.

This fitting is well-suited for residential and light commercial applications where BSPT-threaded branch connections are required inline on a tubing run. The male run tee configuration allows a continuous tube path along the run ports while adding a threaded male branch outlet, enabling a single fitting to serve as both a straight connector and a tapped connection point. Typical install scenarios include control panel pneumatic circuits, instrumentation lines, and light-duty process plumbing where nylon construction is acceptable for the service fluid and temperature range.

Key Features

• Push-to-connect design for tool-free, ferrule-free tube insertion and removal
• 5/16-inch tube outside diameter compatibility on run ports
• 3/8-inch BSPT male thread on branch outlet
• 290 psi pressure rating for moderate-pressure pneumatic and fluid service
• Nylon body construction suitable for lightweight, corrosion-resistant applications
• Male run tee configuration maintains inline tube path while adding a threaded branch point

Compatibility

Designed as an OEM-style push-to-connect fitting for pneumatic and light fluid plumbing systems using 5/16-inch OD tubing with 3/8-inch BSPT threaded ports.

Installation Notes

Installation is performed by qualified plumbers or HVAC technicians familiar with BSPT thread sealing practices. Depressurize and isolate the line completely before disassembling any existing fittings or threading in the new fitting. BSPT threads are taper-seal threads and should be installed with an appropriate thread sealant compatible with the service fluid. Ensure tubing is cut cleanly and squarely and inserted fully into the push-to-connect port until it seats against the internal stop before pressurizing the line.
