0964-0004 - Victor CGA 200 Brass Nut for Acetylene MC Cylinders

Get Your MC Regulator Back in Action

There is nothing more frustrating than gearing up for a job only to find that the threads on your regulator nut are stripped or the nut itself has gone missing. The Victor 0964-0004 Brass Nut is the essential replacement part you need to connect your acetylene regulator to an 'MC' size tank. These smaller tanks are perfect for portable HVAC work, plumbing, and light fabrication, but they require specific CGA 200 fittings that are different from the larger B-tanks or industrial cylinders. This nut is designed to fit those specific valves perfectly.

Built by Victor, a leader in gas equipment, this nut is made from solid brass, meaning it stands up to the wear and tear of the shop or the truck. It features the correct Right-Hand threads for CGA 200 valves, ensuring you don't strip your cylinder valve trying to force a mismatch. It pairs with a standard nipple (sold separately) to create the seal against the tank. Don't risk leaks or accidents with worn-out fittings; swapping out an old, rounded, or cross-threaded nut is a cheap and easy way to ensure your gas flow is safe and steady.

This nut is compatible with any regulator or pigtail designed for the CGA 200 connection. Whether you are repairing an old favorite regulator or building a custom hose assembly, this part gives you the OEM quality fit you expect. Keep a spare in your kit to ensure you are never stuck without a way to hook up your gas. It’s a small part that plays a big role in keeping your flame burning safely.
