Parker MP11083-4 Square Head Pipe Plug 1/2 in Mnptf

Product Description

The PARKER MP11083-4 is a square head pipe plug designed to seal threaded pipe ports in hydraulic, pneumatic, and fluid-handling systems. It features a 1/2 inch male MNPTF (National Pipe Thread Fuel, male) thread and is rated for a maximum working pressure of 1,000 psi. The square head drive allows installation and removal using standard wrenches or socket tools without the need for internal hex or slotted drives. This plug is suited for industrial piping applications where a reliable, pressure-rated thread seal is required. Licensed plumbers, pipefitters, and industrial maintenance technicians are the primary installers of this fitting.

This plug is used in industrial and commercial piping systems to cap or block off threaded pipe ports on manifolds, valves, pumps, cylinders, and similar equipment. Its MNPTF thread classification makes it appropriate for fuel, oil, and fluid service lines where thread-form sealing integrity is critical. The operating temperature range of -65 degrees F to 250 degrees F allows use across refrigeration, hydraulic, and general fluid system environments. Sold in a package quantity of three units per order.

Installation Notes

Installation should be performed by a licensed pipefitter, plumber, or qualified industrial maintenance technician. Always depressurize and de-energize the system before removing or installing pipe plugs. Apply an appropriate thread sealant or PTFE tape to the MNPTF threads before installation to ensure a leak-free seal. Refer to applicable ASME, SAE, or local piping codes for torque and installation requirements.
