Holo-krome 11108 Brass Socket Pressure Plug 1/2-14

Product Description

The HOLO-KROME 11108 is a brass socket pressure plug designed to seal threaded pipe ports and pressure fittings in fluid and pneumatic systems. Sized at 17/32 inches overall length with a 1/2-14 thread, this plug is driven by a 3/8-inch hex key, allowing installation in tight quarters where external wrenches cannot reach. The brass construction provides corrosion resistance suitable for water, oil, and low-pressure pneumatic applications. A 7/8-inch taper per foot conforms to standard pipe thread geometry, ensuring a reliable mechanical seal when properly torqued. Plumbers, pipefitters, and HVAC technicians commonly use socket pressure plugs to cap unused ports on manifolds, valve bodies, and pressure vessels during system service or permanent installation.

This plug is suited for residential and light commercial plumbing, HVAC, and hydraulic applications where a low-profile, recessed-drive plug is required. The hex socket drive allows installation flush with or slightly below the surface of the fitting body. Typical use cases include capping unused tee ports, blanking off test ports on pressure manifolds, and sealing instrument ports during system commissioning or modification. The 1/2-14 thread size is a common pipe thread found across a wide range of fittings, valve bodies, and equipment housings in trade applications.

Key Features

• 1/2-14 pipe thread fits common ports on valves, manifolds, and hydraulic bodies
• 3/8-inch hex key drive allows installation in recessed or confined spaces
• 7/8-inch taper per foot conforms to standard pipe thread geometry for reliable sealing
• Brass material offers corrosion resistance for water, oil, and pneumatic service
• Compact 17/32-inch overall length keeps the plug profile low after installation

Compatibility

Designed as an OEM-style replacement or service plug for threaded pipe ports using 1/2-14 pipe thread, common across residential and commercial plumbing, HVAC, and light hydraulic equipment.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or qualified HVAC technicians. Depressurize and drain the system fully before removing or installing any pipe plug. Apply a compatible thread sealant or PTFE tape to the threads per applicable IPC or IFGC guidelines before seating. Use a calibrated hex key of the correct size to avoid rounding the socket drive.
