Parker 1/2 Hhp-s Hollow Hex Plug 1/2 in Mnptf 6000 Psi

Product Description

The PARKER 1/2 HHP-S is a hollow hex plug designed for industrial pipe systems requiring a reliable male-threaded closure with a center bore passage. Rated to 6000 psi maximum working pressure, this fitting handles high-pressure hydraulic and pneumatic lines where a solid plug is not appropriate. The 1/2 inch MNPTF male thread provides a tapered, pressure-tight connection to female NPT ports. Weighing just 0.01 pounds, it is a compact, lightweight component installed by hydraulic technicians, pipefitters, and industrial maintenance professionals working on high-pressure fluid or gas circuits.

This hollow hex plug is suited for industrial piping and hydraulic applications where a ported or vented plug connection is required at a 1/2 inch female NPT port. Typical install scenarios include hydraulic manifolds, test-port fittings, instrument connections, and high-pressure plumbing assemblies in manufacturing and process environments. Its 6000 psi pressure rating makes it appropriate for demanding hydraulic systems that exceed standard working pressures.

Key Features

• 6000 psi maximum working pressure for high-pressure hydraulic and pneumatic systems
• 1/2 inch MNPTF tapered male thread for a leak-resistant, pressure-tight seal
• Hollow hex body design allows flow or instrumentation passage through the plug
• 3/8 inch hex size for standard wrench installation and removal
• Overall length of 5/8 inch for compact fitment in tight assemblies

Compatibility

Designed as an OEM-style replacement or service fitting for industrial pipe and hydraulic systems using 1/2 inch female NPT ports rated for MNPTF tapered thread connections.

Installation Notes

Installation is performed by licensed pipefitters or hydraulic technicians. Depressurize and isolate the system completely before removing or installing any pipe fittings. Use a calibrated torque wrench and apply appropriate thread sealant compatible with the system fluid before threading the fitting into the female port. Installations in industrial piping systems should conform to applicable ASME and local pressure piping codes.
