Western Enterprises 321 Acetylene Cylinder Adapter Brass

Product Description

The WESTERN ENTERPRISES 321 is a brass acetylene cylinder adapter designed to connect a regulator to a cylinder or other gas equipment when mismatched CGA threads make a direct connection impossible. Built from brass, this adapter provides a reliable mechanical interface between components with differing thread standards. Licensed gas equipment technicians and welding supply professionals install this type of adapter as part of regulator and cylinder hookup procedures. Proper adapter selection is critical to ensuring regulators and associated equipment are used only with gases and pressure ratings they are rated for.

This adapter is intended for acetylene cylinder service, where CGA thread compatibility between the regulator and cylinder valve cannot be achieved without an intermediate fitting. It is sold individually and is appropriate for use in welding, cutting, and gas distribution setups that require acetylene as the supply gas. Selection of the correct adapter for the gas type and pressure rating in use is mandatory before installation.

Key Features

• Brass construction for corrosion resistance and durability in gas service applications
• Bridges mismatched CGA threads between regulators and acetylene cylinders
• Compact form factor suited to tight cylinder valve connection points
• Must be matched to compatible gas type and pressure rating before use
• Replace immediately if worn or damaged to maintain safe operation

Compatibility

Designed as an OEM-style replacement adapter for acetylene cylinder regulator connections where differing CGA thread standards prevent direct mating.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed gas systems and applicable safety codes. Shut off all gas supply and relieve system pressure before removing or installing any adapter. Before placing the adapter into service, all components in the adapted system must be thoroughly purged of contaminants, organic material, and residual gases. Never use an adapter to connect equipment to a gas type or pressure rating outside the equipment specifications.
