Holo-krome 10016 Alloy Steel Socket Pressure Plug

Product Description

The HOLO-KROME 10016 is an alloy steel socket pressure plug designed to seal threaded pipe and fitting openings under pressure. The 1-1/4-11-1/2 tapered thread profile provides a secure, leak-resistant closure in hydraulic, pneumatic, and fluid system applications. With an overall length of 13/16 inches and a 3/4-inch hex key drive, this plug is installed using a standard hex key or Allen wrench, making it suitable for tight spaces where a wrench-driven plug may not fit. Plumbers, pipefitters, hydraulic system technicians, and maintenance professionals use this type of fitting plug to cap off ports, test points, and unused outlets.

This socket pressure plug is suited for industrial fluid systems, hydraulic manifolds, pneumatic assemblies, and plumbing test applications. The alloy steel construction provides strength and resistance to deformation under pressure loading. Its compact 13/16-inch OAL makes it a practical choice for close-clearance port locations in manifold blocks and valve bodies. It is appropriate for both initial system builds and field service work where a port needs to be sealed or blanked off.

Key Features

• 1-1/4-11-1/2 tapered thread for a reliable pressure-tight seal
• Alloy steel construction for high-strength performance in demanding fluid system environments
• 13/16-inch overall length suits compact and close-clearance installations
• 3/4-inch hex key drive allows installation with a standard Allen wrench
• 3/4-inch taper per foot thread geometry consistent with standard pipe plug taper specifications

Compatibility

Designed as an OEM-style socket pressure plug for threaded ports using a 1-1/4-11-1/2 thread size in hydraulic, pneumatic, and industrial pipe systems.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or hydraulic technician familiar with tapered pipe thread connections. Depressurize and isolate the system fully before removing or installing any pressure plug. Apply an appropriate thread sealant or PTFE tape to the tapered threads as required by system specifications and applicable codes. Do not overtighten, as tapered threads can crack cast housings or manifold bodies if excessive force is applied.
