Midland Industries 62704MS Hex Locknut 3/4 in 304 Ss

Product Description

The MIDLAND INDUSTRIES 62704MS is a hex locknut in the SP-114 series, manufactured from 304 stainless steel for reliable corrosion resistance in demanding piping applications. With a 3/4-inch nominal size and 3/4-14 NPT thread, this locknut is designed to secure threaded pipe connections and prevent loosening under vibration or pressure. Weighing 0.085 pounds and measuring 1.55 inches in length, 1.4 inches in width, and 0.3 inches in height, it is a compact, durable fitting suited for plumbing, HVAC, and industrial piping systems. Licensed plumbers, pipefitters, and HVAC technicians commonly install this type of hardware during new construction or maintenance work.

This hex locknut is appropriate for use in residential and light commercial piping systems where a threaded pipe must be anchored or locked at a panel, bulkhead, or fitting. The 304 stainless steel construction makes it suitable for applications exposed to moisture, mild chemicals, or corrosive environments. It fits standard 3/4-inch NPT threaded pipe and is part of the SP-114 Fittings product family from Midland Industries. A minimum order quantity of one unit makes it practical for single-repair or retrofit jobs.

Installation Notes

Installation of pipe locknuts should be performed by a licensed plumber or pipefitter in accordance with applicable IPC and local plumbing code requirements. Depressurize and drain the affected pipe section before installing or removing any threaded fittings. Use a properly sized wrench on the hex flats to achieve a secure, leak-free connection without over-torquing the stainless steel threads. Inspect mating threads for damage or contamination before assembly.
