OVERVIEW

Reliable Connection for TIG Cooling Systems

The ESAB 33033 Bulkhead Adapter is a specialized brass fitting designed to facilitate secure fluid connections in welding environments. Specifically engineered as a bulkhead union, this adapter allows you to pass water or gas lines through the metal casing of welding power sources, water coolers, or control panels while maintaining a rigid and sealed connection point.

Constructed from high-grade brass, this adapter offers excellent resistance to corrosion and mechanical wear, making it suitable for the demanding conditions of industrial welding. One end features a 1/4-inch NPT Male thread, a standard size for plumbing and internal machine piping. The opposing end is machined with a 5/8-inch-18 (B-Size) Water Male thread, which is the industry standard for connecting TIG torch water hoses. This configuration is essential for adapting internal plumbing to external torch connections.

Whether you are repairing a damaged connection on an ESAB welder or building a custom water-cooling setup, this bulkhead adapter ensures a professional and leak-free installation. Its precise threading guarantees compatibility with standard hoses and fittings, preventing coolant leaks that could overheat your equipment or cause electrical hazards.

Key Applications

  • Machine Repair: Direct replacement for damaged bulkhead fittings on ESAB power sources.
  • Custom Setups: Ideal for fabricating custom water cooler panels or gas distribution manifolds.
  • TIG Welding: Essential for connecting water-cooled TIG torches to cooling units.

FAQ

One end is 1/4" NPT Male, and the other is 5/8"-18 (B-Size) Water Male.

The 'W' designation and B-Size thread typically indicate it is designed for water connections, though brass is compatible with inert gases as well.

This product is typically sold as the brass adapter body only; retaining nuts are usually sold separately or reused.

It is made of solid brass.

Yes, as long as the thread specifications (1/4" NPT and 5/8"-18) match your requirements, it can be used on any equipment.

A bulkhead fitting is designed to pass a pipe or tube connection through a wall or panel, allowing fluid to flow freely while maintaining a seal across the barrier.

Water fittings in welding (B-Size) are typically Left Hand threads to distinguish them from gas, but check your specific hose; some adapters may be Right Hand depending on the specific 'W*M' designation.
