Midland Industries 62708MS Hex Locknut 2 in 304 Ss

Product Description

The MIDLAND INDUSTRIES 62708MS is a 2-inch nominal hex locknut machined from 304 stainless steel. It is designed to secure threaded pipe connections against loosening caused by vibration, thermal cycling, or mechanical stress. The 2-11-1/2 NPT thread form ensures a standard fit across compatible pipe and fitting assemblies. At 0.395 pounds, it is a solid, full-bodied fitting suited for industrial and commercial plumbing, process piping, and fluid handling systems. Licensed plumbers and pipefitters install this type of locknut when a positive mechanical stop or panel-mount retention is required on threaded pipe runs.

This locknut is used in residential and commercial piping systems where a corrosion-resistant, standard-thread fitting is required. It fits into the SP-114 304 stainless steel fittings line, making it a common choice for water treatment, food service, marine, and chemical-exposure environments where carbon steel fittings are not appropriate. Typical applications include panel penetrations, bulkhead-style installations, and anywhere a threaded pipe must be locked in position against a surface or mating component.

Key Features

• 2-inch nominal size with 2-11-1/2 NPT thread form for standard pipe fitment
• 304 stainless steel construction resists corrosion in wet, chemical, and outdoor environments
• Hex body profile allows standard wrench engagement for proper torque application
• Part of the SP-114 304 SS fittings series for consistent material compatibility across assemblies
• Low 1-piece minimum order quantity suits both service calls and project procurement

Compatibility

Designed as an OEM-style threaded fitting for use in 2-inch NPT piping systems requiring 304 stainless steel locknuts.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC or local plumbing code requirements. Shut off and depressurize the affected pipe section before installing or removing any threaded fittings. Use a properly sized pipe wrench or hex wrench on the flat faces of the locknut - do not use pliers or tools that may damage the hex profile. Apply thread sealant or PTFE tape as required by the application and local code.
