Product Description

The VALUE COLLECTION -12147-2 is a forged carbon steel hex plug designed to seal threaded pipe openings in pressurized fluid and gas systems. Sized at 3/8 inch NPT, it carries a Class 3000 pressure rating of 3000 psi, making it suitable for demanding industrial and mechanical piping applications. The black finish provides basic corrosion resistance for standard service conditions. This fitting is installed by plumbers, pipefitters, HVAC technicians, and mechanical contractors working on pipe assemblies that require a reliable, code-compliant dead-end closure.

This hex plug is used to close off unused branch outlets, test ports, or pipe ends in residential and commercial piping systems carrying liquids or gases. The 3/8 inch NPT thread size fits commonly used pipe headers, manifolds, and fittings found in heating systems, compressed air lines, hydraulic circuits, and general plumbing distribution. It is sold in a pack of 5, making it practical for service trucks and maintenance stock. Each plug is individually suitable for a single threaded port closure.

Installation Notes

Installation is performed by licensed plumbers, pipefitters, or HVAC technicians in accordance with applicable mechanical and plumbing codes such as the IPC and IFGC. Depressurize and isolate the pipe section before installing or removing any threaded fitting. Apply thread sealant or PTFE tape to the NPT threads before installation and tighten to proper engagement using a wrench on the hex head. Do not over-torque, as this can crack fittings or damage mating threads.
