Parker 1/4 Mmo-s Female Tee 1/4 Inch Fnptf 5000 Psi

Product Description

The PARKER 1/4 MMO-S is a female tee fitting designed for high-pressure industrial pipe systems. It features three female FNPTF (Female National Pipe Taper Fuel) threaded ports, all sized at 1/4 inch, allowing a single inline connection to branch off to a third line without additional adapters. Built from zinc-plated steel, the fitting resists corrosion in demanding shop and field environments. It is rated for a maximum working pressure of 5,000 psi, making it suitable for hydraulic, pneumatic, and fluid-transfer applications where pressure integrity is critical. Licensed plumbers, pipefitters, and hydraulic technicians are the primary installers.

This fitting is used in industrial and commercial piping assemblies where a tee branch is needed at a 1/4 inch FNPTF connection point. Typical applications include compressed-air distribution lines, hydraulic manifold assemblies, fuel-system plumbing, and general fluid-handling networks that require a reliable, all-threaded branch point. The zinc-plated steel construction holds up in environments with moderate moisture exposure.

Key Features

• All three ports are 1/4 inch FNPTF threaded for consistent, leak-resistant connections
• Maximum working pressure of 5,000 psi suits high-pressure hydraulic and pneumatic lines
• Zinc-plated steel construction provides corrosion resistance in industrial environments
• Tee configuration allows a single line to branch in three directions without additional fittings
• Compact design fits tight plumbing assemblies common in industrial equipment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial pipe systems using 1/4 inch FNPTF threaded connections rated up to 5,000 psi.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified hydraulic technician following applicable codes such as the IPC or relevant OSHA pressure-system standards. Depressurize and isolate the system completely before removing any existing fittings or installing this tee. Apply an appropriate thread sealant or PTFE tape to the male threads mating to this fitting — do not apply sealant inside the female ports. Tighten to snug-plus-turns using a pipe wrench; do not overtighten, as steel threads can be damaged by excessive force.
