Value Collection -12128-3 1/2 Inch Npt Cap Class 3000

Product Description

The VALUE COLLECTION -12128-3 is a forged carbon steel pipe cap designed to terminate and seal open pipe ends in pressurized piping systems. Rated at 3000 psi and built to Class 3000 standards, this cap is suited for demanding liquid and gas service applications. The black finish provides basic corrosion resistance for typical industrial and mechanical installations. With a 1/2 inch NPT threaded end connection, it threads directly onto standard male pipe threads without additional fittings. Licensed plumbers and pipefitters install these caps during system testing, permanent line terminations, and system modifications.

This cap is appropriate for residential and light commercial plumbing, HVAC hydronic systems, gas distribution lines, and industrial piping where 1/2 inch NPT threaded fittings are required. The Class 3000 pressure rating makes it suitable for higher-pressure service beyond standard 150-class fittings. It is sold in a package of 5 units, making it practical for service vehicles or supply rooms where multiple caps are needed at a time.

Key Features

• Forged carbon steel construction for strength under high-pressure service
• Class 3000 rated at 3000 psi for liquid and gas pressure applications
• 1/2 inch NPT female threaded end connection for standard pipe compatibility
• Black finish applied over forged carbon steel body
• Sold in a package of 5 for efficient stocking and multi-cap jobs

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1/2 inch NPT male-threaded pipe ends in Class 3000 forged carbon steel piping systems handling liquid or gas service.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC code requirements for the service type. Apply an appropriate thread sealant or PTFE tape to the male pipe threads before threading on the cap. Shut off and depressurize the line completely before installing or removing any threaded fitting. Do not over-torque forged fittings, as thread damage can compromise the pressure seal.
