Value Collection -12148-2 Square Plug 3/8 Inch Npt Class 3000

Product Description

The VALUE COLLECTION -12148-2 is a 3/8 inch NPT square plug used to seal threaded pipe openings in piping systems. Manufactured from forged carbon steel with a black finish, this plug is rated for Class 3000 service, making it suitable for high-pressure liquid and gas applications at up to 3000 psi. The square-head drive style allows installation with a standard wrench. It is sold in a package of five pieces and is typically installed by licensed plumbers, pipefitters, or HVAC technicians during system assembly, maintenance, or pressure testing procedures.

This square plug is designed for use in threaded pipe systems requiring a reliable, pressure-rated closure on an unused port or branch connection. Class 3000 forged carbon steel fittings are commonly specified in industrial, commercial, and mechanical system piping where pressure demands exceed the capacity of standard malleable iron fittings. Typical applications include steam, water, oil, and gas distribution piping using NPT-threaded connections.

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/8 inch NPT-threaded pipe systems requiring Class 3000 forged carbon steel square plugs.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local mechanical and plumbing codes. De-pressurize and isolate the pipe system completely before installing or removing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to the male NPT threads before engagement. Do not over-tighten, as forged fittings can crack pipe threads if excessive force is applied.
