OVERVIEW

Professional Gas Distribution Components

The ESAB 58V58 Bulkhead Adapter is a critical component for industrial gas management systems, specifically designed to facilitate the secure passage of inert gas lines through structural barriers such as machine casings, control panels, or workstation walls. Manufactured to the highest standards of precision, this fitting exemplifies the reliability required in professional MRO (Maintenance, Repair, and Operations) environments where gas leak prevention and system integrity are paramount.

Constructed from high-grade brass, the 58V58 offers superior resistance to corrosion and mechanical deformation, ensuring a long service life even in demanding workshop conditions. The adapter features a dual-thread configuration: one end presents a standard CGA 032 style connection (5/8"-18 Right-Hand Female), commonly known as "B-Size" for inert gases, while the opposing end utilizes a 1/4" National Pipe Taper (NPT) Male thread. This combination allows for the seamless integration of standard welding gas hoses with rigid piping systems or regulators situated on opposite sides of a partition.

In complex manufacturing setups, organized gas routing is essential for safety and efficiency. The bulkhead design of this adapter includes the necessary geometry to be secured against a panel, providing a rigid anchor point that prevents stress on the gas lines during operation. Whether you are retrofitting an automated welding cell, repairing a power source's internal plumbing, or designing a custom manifold system for Argon, Helium, or Nitrogen, the ESAB 58V58 delivers the dimensional accuracy and pressure rating requisite for industrial applications.

By utilizing standardized fittings like the 58V58, facility managers and technicians can ensure compatibility across a wide range of equipment brands and gas delivery systems. This component is an essential stock item for maintenance departments responsible for the upkeep of TIG and MIG welding stations, ensuring that downtime due to gas delivery issues is minimized through the use of reliable, high-quality brass fittings.

FAQ

The ESAB 58V58 features a 5/8"-18 Right-Hand Female thread (CGA 032 style) on one side and a 1/4" NPT Male thread on the other.

No, this adapter is designed for inert gases. While the NPT side is universal, the 5/8"-18 RH Female is typically for inert gas. Oxygen fittings are usually RH but different seating, and fuel gases use Left-Hand threads. Always check CGA standards.

This adapter is manufactured from high-quality brass, providing durability and resistance to corrosion.

Bulkhead fittings typically require a separate nut for panel mounting unless specified as a kit. Please verify the specific packaging contents, but often the backing nut is sold separately or included depending on the specific 'Western' part number variation.

A bulkhead adapter is used to create a secure connection point through a wall or panel, allowing fluid or gas to pass through without exposing the hose or pipe to abrasion from the panel hole.

Yes, the 5/8"-18 RH thread is the standard outlet size for many inert gas regulators and hoses (B-Size).

Standard brass fittings of this type are generally rated for service pressures up to 200-3000 PSIG depending on the specific application, but for welding gas distribution, they easily handle standard delivery pressures (typically under 50 PSI).

You should use Teflon tape or pipe sealant on the 1/4" NPT Male threads. Do NOT use tape on the 5/8"-18 Female side, as that connection relies on a mechanical seat (nipple and nut) to seal.
