Product Snapshot
The Inert Arc Nipple is a brass fitting designed to connect inert gas supply lines to TIG (tungsten inert gas) and MIG (metal inert gas) welding equipment. This B-Size nipple features 5/8 in-18 threading and is rated for 200 PSIG operating pressure, providing a secure, leak-resistant connection for argon, helium, and other shielding gases used in arc welding applications.
Constructed from durable brass, this nipple delivers reliable performance in demanding welding environments. The precision-machined threads ensure proper mating with B-Size regulators, hoses, and torch assemblies. Brass construction provides excellent corrosion resistance and maintains dimensional stability under pressure, making it suitable for both shop and field welding operations.
Key Features
