Parker 1/4 Shp-s Square Head Pipe Plug Mnptf 6000 Psi

Product Description

The PARKER 1/4 SHP-S is a steel square head pipe plug designed to seal threaded pipe ports in high-pressure industrial systems. It features a 1/4 inch male MNPTF (dry-seal) thread and is rated to 6,000 psi, making it suitable for hydraulic, pneumatic, and fluid power applications where a reliable, leak-free closure is required. The square head drive allows installation and removal with standard open-end or box wrenches. At 0.75 inches in length and 0.5 inches in width, this is a compact plug suited for tight manifold and valve body port work.

This plug is used in industrial piping systems, hydraulic manifolds, valve bodies, and fluid power assemblies requiring a positive port seal. Typical install scenarios include capping unused ports on hydraulic cylinders, blocking off test ports, and sealing distribution blocks in mobile and stationary equipment. It is sold individually but has a minimum order quantity of 5 units, making it practical for service kits and fleet maintenance stock.

Installation Notes

Installation is performed by qualified hydraulic or pipefitting technicians. Always depressurize and de-energize the system before removing or installing pipe plugs. Apply appropriate thread sealant or verify dry-seal compatibility before installation. Follow applicable system pressure ratings and torque the plug to the fitting manufacturer specifications using a calibrated torque wrench.
