Value Collection 233004PR Socket Pressure Plug 1/8-27

Product Description

The VALUE COLLECTION 233004PR is a socket pressure plug designed to seal threaded ports in hydraulic, pneumatic, and fluid system applications. It features a 1/8-27 NPTF thread, which provides a pressure-tight mechanical seal without requiring additional sealant tape or compound when properly torqued into a mating female port. Machined from alloy steel in an uncoated finish, this plug is built for durability in high-pressure environments. The hex socket drive accepts a 9/64-inch hex key for installation and removal in confined spaces. Taper is 7/8 inch per foot, consistent with NPTF standards for reliable interference fit sealing.

This plug is used to cap or blank off unused threaded ports on hydraulic manifolds, pneumatic valve bodies, fluid power cylinders, compressor housings, and similar industrial or trade equipment. It is appropriate for both shop fabrication and field service work where a clean, pressure-rated port closure is needed. Licensed machinists, pipefitters, millwrights, and industrial maintenance technicians are the typical installers. Its compact size makes it useful in tight-clearance installations where larger hex head plugs cannot be driven.

Key Features

• 1/8-27 NPTF thread provides a pressure-tight taper fit seal in mating ports
• Alloy steel construction for strength in high-pressure and high-cycle applications
• 9/64-inch internal hex socket drive allows installation with a standard hex key in restricted spaces
• 7/8-inch-per-foot taper conforms to NPTF thread standard geometry
• Uncoated finish suitable for use across a range of fluid and pneumatic media

Compatibility

Designed as an OEM-style replacement or service plug for any hydraulic, pneumatic, or fluid system component with a standard 1/8-27 NPTF female port.

Installation Notes

Installation is performed by pipefitters, hydraulic technicians, or industrial maintenance personnel. Before installing, depressurize and bleed down the system fully and isolate any fluid supply lines to the port being plugged. Use a calibrated hex key of the correct 9/64-inch size to avoid rounding the socket drive. NPTF threads are designed to seal on thread interference, but inspect threads for damage or contamination before assembly to ensure a leak-free joint.
