Midland Industries 67769 Hex Socket Countersunk Plug 2in Mnpt

Product Description

The MIDLAND INDUSTRIES 67769 is a hex socket countersunk plug designed to seal pipe threads in black steel piping systems. It features a 2-inch MNPT (male national pipe thread) connection with a 2-11-1/2 thread specification and meets ASME B16.14-1991 dimensional standards. The plug body is manufactured from black steel and is rated for a 150 lb pressure class. At 0.88 inches in length and 0.86 pounds, this fitting is installed by licensed plumbers and pipefitters during assembly, maintenance, or system modification on threaded steel pipe networks.

This countersunk plug is suited for residential and commercial black steel pipe applications including gas distribution, steam, and hydraulic piping systems where a flush or recessed thread closure is required. The hex socket drive allows installation in tight spaces where a standard hex or square head plug would not fit. It is rated for temperatures ranging from -20 degrees F to 350 degrees F, making it appropriate for a wide range of service conditions in both hot and cold piping configurations.

Key Features

• 2-inch MNPT connection with 2-11-1/2 thread form for standard threaded steel pipe
• 150 lb pressure class rating per ASME B16.14-1991 dimensional standards
• Countersunk hex socket drive (0.1 inch socket size) enables installation in restricted access areas
• Black steel construction provides durability in gas, steam, and hydraulic service
• Temperature range of -20 degrees F to 350 degrees F covers most commercial and residential piping applications
• Compact profile at 0.88 inches in length minimizes protrusion beyond the pipe fitting face

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch threaded black steel pipe systems conforming to ASME B16.14 standards.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes, including ASME and IFGC requirements where applicable. De-pressurize and isolate the pipe system completely before removing or installing any threaded plug. Apply an appropriate thread sealant or PTFE tape rated for the service medium before threading the plug into the female fitting. Use the correct hex key matching the 0.1-inch socket to avoid stripping the drive recess during torquing.
