Value Collection 231010PR Socket Pressure Plug 3/8-18

Product Description

The VALUE COLLECTION 231010PR is a socket pressure plug designed to seal threaded pipe ports and fittings in fluid and pneumatic systems. The plug uses a 3/8-18 NPTF thread, which provides a pressure-tight mechanical seal through thread interference rather than relying solely on a sealant. Constructed from uncoated alloy steel, it is suited for industrial and mechanical applications where strength and thread integrity are required. A 5/16-inch hex key drive allows installation with a standard Allen wrench or hex bit. The taper rate is 3/4 inch per foot, conforming to standard NPTF geometry.

Socket pressure plugs of this type are commonly used by pipefitters, millwrights, and maintenance technicians to blank off unused ports on hydraulic manifolds, pneumatic valve bodies, pump housings, and similar threaded port connections. The NPTF thread form is appropriate for applications where a dry-seal connection is needed without the mandatory use of thread tape or pipe dope, though sealant may still be applied based on system requirements and local practice.

Key Features

• 3/8-18 NPTF thread for pressure-tight dry-seal performance
• Alloy steel construction for high-strength, durable port sealing
• 3/4 inch per foot taper conforms to standard NPTF geometry
• 5/16-inch hex key drive for installation with common Allen wrench or hex bit
• Uncoated finish suitable for industrial mechanical environments

Compatibility

Designed as a standard NPTF-threaded pressure plug for use in hydraulic, pneumatic, and fluid system components that accept a 3/8-18 NPTF port connection.

Installation Notes

Installation is typically performed by pipefitters or maintenance technicians using a 5/16-inch hex key or Allen-drive bit. Always depressurize and isolate the system before removing or installing port plugs. Inspect threads for damage before installation and apply thread sealant if required by system specifications or applicable codes. Do not overtighten, as alloy steel NPTF plugs rely on thread taper engagement for sealing and excessive torque can damage the port.
