Midland Industries 18057 Compression Nut 5/8 Inch Brass

Product Description

The MIDLAND INDUSTRIES 18057 is a nickel-plated brass compression nut designed for 5/8 inch tube connections in plumbing and mechanical systems. This fitting secures tubing within a compression fitting assembly, creating a leak-resistant seal without soldering or threading the tube itself. Brass construction provides corrosion resistance and long service life in wet environments. The nickel plating adds a finished appearance while offering additional surface protection. Plumbers, HVAC technicians, and mechanical contractors use this nut when assembling or servicing compression-style connections on copper or compatible tubing.

This compression nut is suited for residential and light commercial plumbing installations where 5/8 inch tube compression fittings are specified. Common applications include water supply lines, refrigeration tubing connections, and gas line assemblies that call for compression-style hardware. It functions as a replacement nut when original hardware is lost, damaged, or corroded during service work on existing compression fitting assemblies.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off the water supply or isolate the refrigerant circuit before disassembling any compression fitting. Hand-tighten the nut onto the fitting body before applying a final turn with an appropriately sized wrench. Do not overtighten, as brass compression nuts can crack or deform the ferrule if excessive force is applied.
