Parker 1/2 Mro-s Street Tee 1/2 Inch Mnptf Fnptf 3000 Psi

Product Description

The PARKER 1/2 MRO-S is a 1/2-inch industrial pipe street tee fitting designed for high-pressure hydraulic and pneumatic piping systems. It combines a male NPTF thread on one end with female NPTF threads on the remaining ports, allowing a branch connection to be made directly off a run of pipe without a separate coupling. Constructed from zinc-plated steel, it carries a maximum working pressure of 3,000 psi, making it suitable for demanding service environments. Licensed plumbers, pipefitters, and industrial maintenance technicians install this type of fitting in compressed air, hydraulic, and fluid transfer lines where a tee branch is needed in tight quarters.

This street tee is sized at 1/2 inch across all ports and uses National Pipe Taper Fuel thread form, meeting SAE 140424 standards. It is suited for residential and commercial mechanical rooms, industrial machinery, and process piping applications where a compact inline tee configuration is required. The male-by-female NPTF thread design eliminates the need for an additional pipe nipple at the branch, saving space and reducing potential leak points in the assembly.

Key Features

• 3,000 psi maximum working pressure rated for high-pressure service
• MNPTF x FNPTF connection type allows direct in-line street tee installation
• Zinc-plated steel construction provides corrosion resistance in typical piping environments
• NPTF thread form creates a pressure-tight seal without relying solely on thread sealant
• Meets SAE 140424 standard for industrial pipe fittings
• Compact street tee configuration reduces overall assembly length compared to standard tee plus nipple

Compatibility

Designed as an OEM-style replacement or maintenance fitting for 1/2-inch NPTF industrial pipe systems operating up to 3,000 psi.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the line completely before disassembling any threaded pipe fitting. Apply an appropriate thread sealant or PTFE tape to male threads per the system fluid and pressure requirements. Torque to fitting manufacturer and applicable code recommendations, referencing IFGC, IPC, or applicable ANSI standards as required by the installation jurisdiction.
