Ham-let 3001199 Pipe Plug 3/4 Inch 316 Ss Mnpt 6800 Psi

Product Description

The HAM-LET 3001199 is a 3/4-inch MNPT threaded pipe plug manufactured from 316 stainless steel. It is designed to close off the end of a threaded pipe or fitting, blocking flow and maintaining system integrity under pressure. Rated to 6,800 psi, this plug is built for demanding industrial and process piping applications where corrosion resistance and pressure containment are critical. It meets ANSI B 31.1 Refiner Piping Code and ASME/ANSI B1.20.1 (1983) thread standards. Licensed plumbers and pipefitters install this type of fitting during system construction, pressure testing, or maintenance isolation procedures.

This pipe plug is suited for use in industrial process piping, refineries, chemical handling systems, and high-pressure fluid or gas lines where 316 stainless steel is specified for corrosion resistance. The 3/4-inch MNPT thread size fits standard NPT female-threaded pipe ends, tees, crosses, and manifold ports. It is appropriate for both new installations and retrofit work in commercial and industrial environments where code-compliant threaded fittings are required.

Key Features

• 316 stainless steel construction resists corrosion in harsh chemical and process environments
• Pressure rated to 6,800 psi for high-pressure piping systems
• 3/4-inch MNPT thread conforms to ASME/ANSI B1.20.1 (1983) for consistent fit with standard NPT female connections
• Compliant with ANSI B 31.1 Refiner Piping Code for industrial process piping applications
• Threaded end connection allows straightforward installation and removal without special tooling

Compatibility

Designed as an OEM-style threaded pipe plug for standard 3/4-inch NPT female-threaded pipe ends, fittings, and manifolds in industrial and process piping systems.

Installation Notes

Installation is typically performed by a licensed pipefitter or plumber. Depressurize and isolate the line completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape to the male threads in accordance with the applicable piping code before torquing the plug into place. Follow ANSI B 31.1 or the governing piping code for inspection and pressure testing requirements after installation.
