Parker 3/8 Mmo-s Female Tee 3/8 Inch Fnptf 4500 Psi

Product Description

The PARKER 3/8 MMO-S is a zinc-plated steel female tee fitting designed for industrial pipe assemblies requiring a three-way split in a fluid or gas line. The fitting uses female National Pipe Taper Fuel (FNPTF) threads on all three ports, with a 3/8 inch thread size throughout. It carries a maximum working pressure rating of 4,500 psi, making it suitable for high-pressure hydraulic and pneumatic systems. Plumbers, pipefitters, and industrial maintenance technicians install this type of fitting when a single supply line must branch into two downstream connections without adapters or reducers.

This tee fitting is used in industrial piping systems where threaded steel connections are required. Typical applications include hydraulic power units, compressed air distribution, lubrication lines, and other high-pressure fluid circuits. The FNPTF thread form provides a pressure-tight seal on fuel and fluid service lines. It is well suited for both new installations and maintenance replacements in manufacturing, processing, and heavy equipment environments where reliable threaded connections are critical.

Key Features

• Maximum working pressure of 4,500 psi for high-pressure service
• FNPTF thread type on all ports for a pressure-tight threaded seal
• 3/8 inch female thread size throughout all three ports
• Zinc-plated steel construction for corrosion resistance in industrial environments
• Tee configuration allows a single line to branch into two outlet paths

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial pipe systems using 3/8 inch FNPTF threaded connections rated for high-pressure service.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber in accordance with applicable local codes and system design requirements. Depressurize and isolate the line completely before removing any existing fitting or threading the new connection. Use appropriate thread sealant rated for the fluid service and pressure involved. Do not overtighten threaded connections; follow standard pipe thread engagement practices to avoid thread damage or fitting failure.
