Midland Industries 44701 Hex Locknut 1/4 in Fpt Bronze

Product Description

The MIDLAND INDUSTRIES 44701 is a bronze hex locknut designed to secure threaded pipe connections in a wide range of fluid and gas systems. With a 1/4 inch female pipe thread (FPT) connection and a 0.66 inch hex body, this locknut provides a firm, vibration-resistant grip on fittings and adapters. It meets ANSI B16.15 dimensional standards and carries a 125 pressure class rating. The compact design measures 0.25 inches in thickness and weighs approximately 0.035 pounds. Plumbers, pipefitters, and mechanical contractors install this fitting where a positive locking hold is required on threaded connections in light-duty service systems.

This hex locknut is rated for use across multiple media including steam, water, gas, oil, and compressed air service. Its bronze construction makes it well-suited for residential and light commercial plumbing, HVAC, and mechanical piping applications where corrosion resistance and reliable sealing are required. The 125 pressure class rating positions it for standard-pressure systems. It is a direct-fit component in any application requiring a 1/4 inch FPT threaded locknut conforming to ANSI B16.15 standards.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC depending on the media being conveyed.
