Value Collection -12147-1 1/4 Inch Npt Hex Plug Class 3000

Product Description

The VALUE COLLECTION -12147-1 is a forged carbon steel hex plug rated for Class 3000 service. It is designed to seal threaded pipe openings in pressurized piping systems carrying liquid or gas. The plug features a black finish and a 1/4 inch NPT male thread connection. With a pressure rating of 3000 psi, it is suitable for demanding industrial and mechanical piping applications. Plumbers, pipefitters, and mechanical contractors install this type of plug during system assembly, testing, or maintenance to cap unused ports and prevent leaks.

This hex plug is used across a range of piping system applications where a threaded cap or dead-end closure is required. Typical installations include industrial process piping, compressed air lines, hydraulic systems, and plumbing rough-in work. The Class 3000 rating makes it appropriate for higher-pressure systems that exceed standard 150 or 300 class fittings. The 1/4 inch NPT sizing suits smaller branch lines and instrument taps.

Key Features

• 1/4 inch NPT male thread for secure, leak-resistant sealing of pipe openings
• Class 3000 pressure rating with 3000 psi liquid and gas pressure capacity
• Forged carbon steel construction for strength and durability in pressurized service
• Black finish provides corrosion resistance for typical indoor piping environments
• Hex head design allows installation and removal with standard wrenches
• Sold in a package of 5 pieces, suitable for multi-point installations

Compatibility

Designed as an OEM-style replacement or standard fitting for Class 3000 forged carbon steel threaded piping systems using 1/4 inch NPT connections.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes such as the IPC or IFGC. Depressurize and isolate the piping system completely before installing or removing any threaded plug. Apply appropriate thread sealant or PTFE tape to the NPT threads prior to installation. Do not overtighten, as forged fittings can crack if excess torque is applied to small-diameter threads.
