Midland Industries 62632B1 Barstock Hex Head Plug 3/8 Mpt

Product Description

The MIDLAND INDUSTRIES 62632B1 is a barstock hex head plug designed to seal off pipe threads in pressurized fluid and gas systems. Machined from 304 stainless steel, it offers strong corrosion resistance across a wide range of industrial and mechanical applications. The 3/8 inch male pipe thread (MPT) connection provides a secure, leak-tight fit when installed into a female-threaded port or fitting. Rated for service at 1000 to 3000 lb pressure class, this plug is suited for demanding installations where carbon steel or brass plugs would be inadequate. It is typically installed by licensed plumbers, pipefitters, or HVAC technicians closing off unused ports in piping assemblies.

This plug fits standard applications in plumbing, HVAC, industrial piping, and process systems where a 3/8 inch MPT closure is required. It is commonly used to cap tees, crosses, or manifold ports during system assembly or service. The 304 stainless steel construction makes it appropriate for environments with exposure to moisture, mild chemicals, or corrosive atmospheres. Its compact hex head profile accepts standard wrench sizes for straightforward installation in tight spaces.

Key Features

• 304 stainless steel construction for corrosion resistance in wet and chemical-exposure environments
• 3/8 inch MPT connection seals standard female-threaded pipe ports
• Rated 1000 to 3000 lb pressure class for use in high-pressure piping systems
• Hex head design accepts standard wrenches for controlled installation torque
• Barstock machining provides consistent dimensional accuracy and thread quality
• Lightweight at 0.08 pounds, minimizing load on threaded fittings and manifolds

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/8 inch female NPT ports in 1000 lb and above pressure-class piping systems fabricated with 304 stainless steel fittings.

Installation Notes

Installation is performed by licensed plumbers or pipefitters in accordance with applicable IPC or IFGC code requirements. Always depressurize and isolate the piping system before installing or removing threaded plugs. Apply an appropriate thread sealant or PTFE tape to the MPT threads before installation to ensure a leak-tight seal. Do not over-tighten, as excessive torque can damage the female threads in the mating fitting.
