Western Enterprises wmh-2-8 Argon Cryogenic Pigtail

Product Description

The WESTERN ENTERPRISES wmh-2-8 is a 6-foot cryogenic pigtail hose assembly designed for argon gas service. It features a nylon braided inner construction with a black polyurethane outer wrap, combining flexibility with durability in demanding gas distribution applications. This pigtail is built to connect CGA-580 fittings, making it a direct-service connection component used between argon cylinders and regulators or manifold systems. Welding supply houses, industrial gas distributors, and specialty gas technicians rely on this style of pigtail for reliable, low-permeability argon transfer in both shop and field setups.

This pigtail is suited for use in welding and fabrication environments, laboratory gas supply systems, and industrial facilities where argon is distributed from high-pressure cylinders. The CGA-580 connection standard is the industry designation for non-flammable, non-oxidizing gases including argon, helium, and nitrogen, so this assembly is commonly found in MIG and TIG welding stations, purge gas setups, and inert atmosphere applications. It is installed by welding equipment technicians, industrial gas service professionals, and licensed pipefitters working with inert gas distribution systems.

Key Features

• 6-foot length provides working reach between cylinder and regulator or manifold
• Nylon braided construction adds pressure resistance and flexibility
• Black polyurethane outer wrap protects against abrasion and environmental wear
• CGA-580 fitting compatibility matches the standard for argon, helium, and nitrogen service
• Cryogenic-rated design supports low-temperature inert gas applications

Compatibility

Designed for CGA-580 argon gas service connections, consistent with standard argon cylinder and regulator fitting configurations used in welding and industrial gas applications.

Installation Notes

Installation should be performed by a qualified welding equipment technician or industrial gas professional familiar with high-pressure inert gas systems. Always close the cylinder valve and bleed downstream pressure before disconnecting or connecting the pigtail. Inspect the hose assembly and fittings for damage or thread wear before each installation. Hand-tighten CGA fittings first, then use an appropriate wrench to achieve a leak-free seal without overtightening, and verify connections with an approved leak-detection solution before returning the system to service.
