Superior N-705 Hex Nut CGA-702 Air Service

Product Description

The SUPERIOR N-705 is a CGA-702 standard hex nut designed for compressed air cylinder valve connections. Manufactured from chrome-plated brass, it provides a durable, corrosion-resistant mating surface for high-pressure gas fittings. The external thread configuration is 1.120 inches-14NGO-RH-EXT, and the nut is rated for working pressures from 5501 to 7500 psi. This fitting is installed by licensed gas technicians, industrial maintenance professionals, and compressed gas equipment specialists during cylinder valve assembly or regulator connection work.

This hex nut is used in compressed air service applications where CGA-702 connections are specified. It is suited for both industrial and commercial environments where high-pressure cylinder valve assemblies require a reliable, standards-compliant threaded connection. The chrome-plated brass construction holds up to the demands of pressurized air systems without introducing contamination risk at the connection point.

Installation Notes

Installation should be performed by qualified gas equipment technicians familiar with CGA fitting standards and high-pressure compressed gas safety practices. Always depressurize and isolate the cylinder before servicing any valve or connection hardware. Use the appropriate open-end or box wrench sized for the hex nut — do not use adjustable tools that may round the fitting. Inspect threads for damage or contamination before assembly and ensure thread engagement is full before applying pressure.
