Parker 1/2 Mms-s Male Branch Tee 3000 Psi Mnptf Fnptf

Product Description

The PARKER 1/2 MMS-S is a male branch tee fitting designed for high-pressure industrial pipe systems. It accepts a 1/2-inch male NPTF thread on the branch port and 1/2-inch female NPTF threads on the remaining ports, providing a secure, leak-resistant connection in hydraulic and pneumatic plumbing applications. Constructed from zinc-plated steel, it carries a maximum working pressure rating of 3,000 psi. This fitting is typically installed by industrial maintenance technicians, pipefitters, and fluid-power specialists working on hydraulic lines, lubrication systems, and general fluid-transfer assemblies.

This male branch tee is suited for industrial piping applications where a branch connection must be introduced into an existing line. The MNPTF x FNPTF configuration allows direct thread-to-port engagement, minimizing potential leak paths under pressure. The zinc plating provides a base level of corrosion resistance for shop and light-industrial environments. It is sold individually and is appropriate for use in hydraulic power units, machine tool coolant circuits, and similar fluid-power installations.

Key Features

• Maximum working pressure of 3,000 psi for demanding hydraulic and pneumatic applications
• MNPTF x FNPTF thread configuration for pressure-tight, dryseal connections
• 1/2-inch male and 1/2-inch female NPTF thread sizes on all ports
• Zinc-plated steel construction offers corrosion resistance in light-industrial environments
• Tee shape enables branch connections without cutting or rerouting the main line
• Meets SAE 140425 standards for industrial pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for industrial hydraulic and pneumatic pipe systems using 1/2-inch NPTF threaded connections rated up to 3,000 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or fluid-power technician. Depressurize and lock out the system fully before removing any existing fittings or installing this tee. NPTF dryseal threads are designed to seal on the threads themselves; apply thread sealant only as required by the system specification, and do not overtighten, as this can crack the fitting body. Follow applicable ASME and OSHA guidelines for pressurized fluid systems during assembly and post-installation pressure testing.
