Matco-norca mn-ft3ca04 Forged Steel Pipe Cap 3/4 in CL3000

Product Description

The MATCO-NORCA mn-ft3ca04 is a Class 3000 forged steel threaded pipe cap designed to terminate open pipe ends in high-pressure piping systems. Manufactured to ASTM A105N material standards, this cap provides reliable dead-end closure on 3/4-inch threaded connections. The forged construction delivers consistent wall integrity, with a wall thickness of 0.25 inches (6.4 mm) suited for demanding service conditions. Licensed plumbers, pipefitters, and mechanical contractors install this fitting in industrial, commercial, and heavy-duty residential piping assemblies where pressure ratings and material traceability are required by specification.

This cap is used to close off 3/4-inch NPT pipe ends in steam, oil, gas, and water piping systems where a Class 3000 pressure rating is specified. It is a standard fitting choice in process piping, boiler rooms, mechanical rooms, and similar environments that call for forged carbon steel fittings conforming to ASTM A105N. The threaded connection allows for tool-on installation without welding, making it practical for maintenance, testing, and isolation applications.

Key Features

• Forged steel construction per ASTM A105N for verified material traceability
• Class 3000 pressure rating suitable for high-pressure service
• 3/4-inch threaded connection for tool-on installation without welding
• Wall thickness of 0.25 inches (6.4 mm) for structural integrity under pressure
• Compact profile at approximately 1.38 inches diameter and 1.46 inches length

Compatibility

Designed as an OEM-style threaded pipe cap for 3/4-inch NPT piping systems requiring Class 3000 forged carbon steel fittings.

Installation Notes

Installation is performed by licensed plumbers or certified pipefitters following applicable code requirements, including ASME B16.11 for forged fittings. Depressurize and isolate the pipe section completely before removing any existing fitting or installing this cap. Apply an appropriate thread sealant or PTFE tape to the male threads before engagement. Do not over-torque; follow standard practice for steel threaded fittings of this size class.
