Parker 1/8 Mro-s Pipe Street Tee 1/8 in Mnptf Fnptf 5000 Psi

Product Description

The PARKER 1/8 MRO-S is a steel industrial pipe street tee designed for high-pressure fluid and pneumatic systems. It combines a male NPTF (MNPTF) run connection with a female NPTF (FNPTF) branch, allowing a straight-through male thread to be inserted directly into a female port while the tee leg accepts a separate connection. Rated to 5,000 psi maximum working pressure, this fitting is built for demanding service in industrial, hydraulic, and fluid-transfer applications. Licensed plumbers, pipefitters, and industrial maintenance technicians install this fitting in compressed air, hydraulic, and high-pressure fluid lines where a compact, reliable tee connection is required.

This street tee is suited for industrial piping systems where space is limited and a traditional tee with separate nipple would add unnecessary length. The 1/8 inch thread size makes it appropriate for small-bore hydraulic circuits, pneumatic control lines, instrumentation plumbing, and similar applications. It conforms to SAE 140424 standards, confirming thread form and pressure integrity for safety-critical installations. Sold individually, it fits into maintenance, repair, and operations (MRO) inventories as a direct replacement or new-installation fitting.

Key Features

• 5,000 psi maximum working pressure for high-pressure hydraulic and pneumatic service
• MNPTF x FNPTF connection eliminates a separate nipple, reducing overall assembly length
• 1/8 inch male and female NPTF threads for pressure-tight, dryseal thread engagement
• Meets SAE 140424 standard for thread form and pressure performance
• Compact tee configuration suited for small-bore instrumentation and control plumbing
• Lightweight at 0.13 pounds, minimizing load on small-diameter piping assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial piping systems using 1/8 inch NPTF-threaded components rated for up to 5,000 psi service.

Installation Notes

Installation is performed by licensed pipefitters, plumbers, or qualified industrial maintenance technicians. Depressurize and isolate the line completely before disassembling any fitting in a hydraulic or pneumatic circuit. NPTF dryseal threads are designed to seal on the thread form itself; consult the applicable system specification before applying thread sealant. Follow IFGC, IPC, or applicable plant safety codes for pressure piping work.
