Parker 1 1/2 Ff-s Hex Plug 1-1/2 in Mnptf 3000 Psi

Product Description

The PARKER 1 1/2 FF-S is a straight hex plug fitting designed for industrial pipe systems requiring a secure, leak-resistant thread closure. With a 1-1/2 inch male MNPTF thread and a maximum working pressure of 3000 psi, this plug is built for demanding hydraulic, pneumatic, and fluid-handling applications. The hex body measures 2 inches across and the overall length is 2-5/8 inches, making it compatible with standard hex wrench installation. Licensed plumbers, pipefitters, and hydraulic technicians use this type of fitting to cap off ports, manifolds, and unused branch connections in high-pressure systems.

This hex plug is suited for industrial and commercial pipe installations where a threaded male closure is needed on MNPTF-tapped ports. Typical applications include hydraulic power units, compressed air distribution systems, fluid manifolds, and industrial machinery service ports. The straight fitting shape makes it a direct, in-line port plug without any offset or angular transition. It is appropriate for both new installation and maintenance work where an existing port must be sealed during service or system reconfiguration.

Key Features

• 1-1/2 inch male MNPTF thread for secure taper-threaded port closure

• 2-inch hex size accommodates standard industrial hex wrenches and sockets
• 2-5/8 inch overall length fits standard MNPTF port depths
• Straight fitting shape provides direct port plug without offset
• Sold individually, single-piece packaging suitable for service calls and stocking

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pipe systems using 1-1/2 inch MNPTF-threaded ports rated to 3000 psi.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or hydraulic technician familiar with MNPTF tapered thread fittings. Depressurize and isolate the system completely before removing or installing any pipe plug. Apply appropriate thread sealant or PTFE tape per system fluid compatibility requirements and applicable plumbing or hydraulic codes. Do not overtighten — use the hex body with a properly sized wrench and follow standard tapered thread engagement practices.
