Holo-krome 12004 Alloy Steel Socket Pressure Plug 1/8-27

Product Description

The HOLO-KROME 12004 is an alloy steel socket pressure plug designed to seal threaded ports and openings in hydraulic, pneumatic, and fluid systems. The plug uses a 1/8-27 tapered thread with a 7/8-inch taper per foot, which provides a mechanical seal as the plug is driven in. Overall length is 1/4 inch. Drive is via a 3/16-inch hex key, making installation and removal straightforward in confined spaces. Alloy steel construction gives the plug the strength and hardness needed to withstand system pressure without deformation or galling. This type of plug is a common maintenance and fabrication component installed by plumbers, pipefitters, hydraulic technicians, and industrial mechanics.

The HOLO-KROME 12004 is suited for sealing unused or temporary ports in pipe assemblies, manifolds, valve bodies, and fluid power components. The 1/8-27 NPT-style tapered thread size is one of the most common small-port sizes found in residential and light commercial plumbing, as well as in hydraulic and pneumatic equipment. It is appropriate anywhere a small, threaded port requires a reliable, pressure-rated blind plug.

Key Features

• 1/8-27 tapered thread provides a self-sealing mechanical fit as the plug is tightened
• 7/8-inch taper per foot conforms to standard pipe thread taper geometry
• Compact 1/4-inch overall length fits flush or near-flush in shallow boss applications
• 3/16-inch hex key drive allows installation in tight, restricted spaces
• Alloy steel construction resists deformation under pressure and repeated service

Compatibility

Designed as an OEM-style replacement or service plug for any application requiring a 1/8-27 threaded socket pressure plug in alloy steel.

Installation Notes

Depressurize and de-energize any system before removing or installing pipe plugs. A licensed plumber, pipefitter, or hydraulic technician should perform installation in pressure systems. Apply appropriate thread sealant or PTFE tape to tapered threads per system fluid and pressure requirements, and follow applicable plumbing or fluid power codes. Do not overtighten; tapered thread engagement provides the seal and excessive torque can crack bosses or damage mating threads.
