36Z40 - ESAB 36Z40 B-Size Hose Nut, 5/8"-18 RH, Brass

Precision Gas Connection Components

The ESAB 36Z40 Hose Nut is a critical component designed for the rigorous demands of industrial welding and cutting environments. Manufactured to precise tolerances, this nut serves as the primary fastening mechanism for securing gas hoses to regulators, torches, and manifold systems. It features the industry-standard B-Size configuration with a 5/8"-18 thread pitch. Specifically machined with Right Hand (RH) threads, this fitting is designated for use with non-fuel gases, including Oxygen, Argon, Helium, and Nitrogen, adhering to CGA safety standards that distinguish gas lines by thread direction to prevent cross-connection accidents.

Material Quality and Durability

Constructed from high-grade brass, the 36Z40 nut offers superior resistance to corrosion and mechanical deformation. Brass is the material of choice for gas fittings due to its non-sparking properties and its ability to maintain a tight seal under fluctuating pressures and temperatures. Unlike inferior alloys that may gall or strip during tightening, this ESAB component ensures smooth engagement with mating threads, prolonging the lifespan of both the nut and the equipment it connects to. The hexagonal outer profile is sized for standard wrenches, allowing for easy installation and removal during maintenance or hose replacement procedures.

Compatibility and Application

This hose nut is engineered to be compatible with a wide range of gas apparatus, particularly legacy and modern equipment from ESAB, L-Tec, Purox, and Oxweld. It is an essential spare part for maintenance departments and fabrication shops, ensuring that compromised fittings can be replaced immediately to maintain operational safety. Whether utilized in oxy-fuel cutting setups or inert gas shielding for TIG and MIG welding, the 36Z40 provides the reliability required for high-purity gas transmission. Its robust design minimizes the risk of leaks, which is paramount for maintaining process consistency and workplace safety.

Industrial Standards Compliance

Adhering to Compressed Gas Association (CGA) specifications, the ESAB 36Z40 ensures interoperability with standard B-Size nipples and fittings found across the North American welding industry. This standardization simplifies inventory management for MRO specialists, as this single part number can service multiple types of gas delivery equipment requiring 5/8"-18 RH connections. By choosing genuine ESAB parts, operators ensure that their equipment maintains its original performance specifications and safety ratings.
