Holo-krome 12006 Alloy Steel Socket Pressure Plug 1/4-18

Product Description

The HOLO-KROME 12006 is an alloy steel socket pressure plug designed to seal threaded ports in hydraulic, pneumatic, and fluid system applications. With a 1/4-18 thread size and an overall length of 13/32 inches, this compact plug installs using a 1/4-inch hex key. The tapered thread profile — 7/8 inches taper per foot — provides a reliable mechanical seal when torqued into standard NPT-tapped ports. Alloy steel construction gives this plug the strength and corrosion resistance needed for demanding industrial and mechanical service environments. Licensed tradespeople and maintenance technicians working on fluid power systems, pipe assemblies, or equipment panels will find this plug a straightforward solution for port sealing.

This pressure plug is suited for use in hydraulic manifolds, pneumatic systems, fluid transfer equipment, and general industrial machinery where a threaded port needs to be sealed against pressure. The 1/4-18 NPT thread size is one of the most common thread designations found in industrial equipment, making this plug a frequent choice for maintenance, repair, and OEM assembly work. It is typically installed by millwrights, pipefitters, hydraulic technicians, and mechanical maintenance crews.

Key Features

• 1/4-18 NPT thread size fits standard tapped ports in industrial fluid and pneumatic systems
• Alloy steel construction provides high tensile strength and durability under pressure
• 13/32-inch overall length keeps the plug compact and low-profile in tight spaces
• 7/8-inch taper per foot thread profile for positive sealing engagement
• 1/4-inch hex key drive allows installation with a standard hex wrench or Allen key

Compatibility

Designed as an OEM-style sealing plug for industrial fluid power, hydraulic, and pneumatic systems with standard 1/4-18 NPT threaded ports.

Installation Notes

Installation is performed by qualified tradespeople familiar with threaded pipe fittings and fluid system assembly. Depressurize and drain the system completely before removing or installing any port plug. Use a calibrated 1/4-inch hex key to drive the plug; do not use impact tools, as overtightening can damage the tapped port or the plug itself. Apply thread sealant appropriate for the fluid or gas service in accordance with applicable system specifications and relevant codes.
