Parker PP4MTS4 Male Swivel Branch Tee 1/4 in Od Nptf

Product Description

The PARKER PP4MTS4 is a push-to-connect male swivel branch tee tube fitting designed for tube-to-pipe connections in fluid handling systems. It accepts 1/4 inch OD tubing on the push-to-connect ports and threads into a 1/4 inch NPTF male port on the branch outlet. Constructed from white polypropylene, the fitting is rated to 150 psi and suits low-pressure pneumatic and liquid plumbing lines. The swivel feature on the branch outlet allows for rotational adjustment during installation, reducing stress on tubing runs. Plumbers, HVAC technicians, and fluid system installers use this fitting to create reliable tee configurations without tools on the tube side.

This fitting is suited for residential and light commercial applications where polypropylene construction is acceptable, including water distribution lines, pneumatic control circuits, and instrument air tubing. The push-to-connect design speeds up assembly in tight spaces or high-density panel work where compression fittings would slow installation. The NPTF thread provides a pressure-tight mechanical seal at the branch connection without relying solely on thread sealant.

Key Features

• Push-to-connect ports accept 1/4 inch OD tubing — no tools required on tube side
• Male swivel branch outlet threads into 1/4 inch NPTF ports
• Polypropylene body rated to 150 psi
• Swivel branch allows rotational positioning after assembly
• White color for easy visual identification in multi-line installations
• Compact, lightweight design at 0.02 pounds

Compatibility

Designed as an OEM-style replacement or new-install fitting for low-pressure pneumatic and liquid plumbing systems using 1/4 inch OD tubing and 1/4 inch NPTF threaded ports.

Installation Notes

Installation is performed by plumbers or HVAC technicians following applicable IPC and system pressure guidelines. Before servicing any existing line, depressurize and drain the system completely. Insert tubing fully into the push-to-connect port until it seats against the internal collet, and hand-tighten the NPTF branch thread using an appropriate thread sealant or tape rated for the fluid service. Do not exceed the 150 psi pressure rating of the polypropylene body.
