Parker 1/2 X 1/4 Ff-s Hex Plug 6000 Psi Mnptf Male Thread

Product Description

The PARKER 1/2 X 1/4 FF-S is a straight hex plug fitting designed for high-pressure industrial pipe systems. It features a male MNPTF (Dryseal) thread connection in a 1/2 x 1/4 inch configuration, allowing technicians to cap or reduce pipe lines without the need for thread sealant tape on the pipe end. Rated to 6,000 psi maximum working pressure, this fitting is built for demanding hydraulic, pneumatic, and fluid power applications. With an overall length of 1-11/16 inches and a 7/8 inch hex size, it is sized for standard hand and socket wrenches used in pipe and fitting work.

This hex plug is suited for industrial and commercial installations where high-pressure line termination or port plugging is required. Typical applications include hydraulic manifolds, pneumatic circuits, fluid distribution systems, and instrumentation lines. The MNPTF thread form provides a pressure-tight metal-to-metal seal, making it appropriate for systems handling oils, gases, water, and other compatible media. It is installed by pipefitters, hydraulic technicians, and industrial maintenance mechanics working on process or fluid power equipment.

Key Features

• Rated to 6,000 psi maximum working pressure for high-pressure service
• MNPTF (Dryseal) thread connection provides a metal-to-metal pressure-tight seal

• 7/8 inch hex size accepts standard hand or socket wrenches
• Overall length of 1-11/16 inches for compact installation in tight spaces
• 1/2 x 1/4 inch male thread size for common pipe reducer or plug applications

Compatibility

Designed as an OEM-style replacement or direct-install hex plug fitting for industrial pipe systems using MNPTF male thread connections in 1/2 x 1/4 inch configurations rated up to 6,000 psi.

Installation Notes

Installation should be performed by a qualified pipefitter or hydraulic technician. De-pressurize and isolate the system completely before removing or installing any fittings. MNPTF dryseal threads are designed to seal on the thread form itself; inspect threads for damage before installation and do not overtighten. Refer to applicable system pressure ratings and relevant industry codes to confirm fitting suitability for the intended service.
