58V75 - ESAB 58V75 TIG Gas Adapter 1/4 NPT Male to 5/8-18 RH Female

Precision ESAB 58V75 TIG Gas Adapter

The ESAB 58V75 is a critical component for TIG welding configurations, specifically designed to adapt standard gas lines to threaded ports on power sources, solenoids, or regulators. Manufactured from high-quality brass, this adapter ensures a corrosion-resistant and durable connection point that withstands the rigors of industrial environments. The fitting features a 1/4-inch National Pipe Taper (NPT) Male thread on one end, which is the industry standard for many welding machine gas outlets and flowmeter connections. On the opposing end, it provides a 5/8-inch - 18 Right Hand (RH) Female thread, compatible with standard "B-size" inert gas hose nuts found on most TIG torch assemblies.

Ensuring a leak-free gas shield is paramount in Gas Tungsten Arc Welding (GTAW) to prevent porosity and tungsten contamination. The ESAB 58V75 is machined to tight tolerances to provide a secure mechanical seal. The hex-shaped body allows for easy installation and removal using standard wrenches, ensuring that torque can be applied without damaging the threads. This adapter is specifically engineered for inert gases such as Argon and Helium mixtures used in TIG welding. It is not intended for water connections or fuel gases, which utilize different thread directions (Left Hand) to prevent cross-connection accidents.

Whether you are setting up a new TIG workstation, replacing a worn fitting, or customizing a gas delivery system, the 58V75 offers universal compatibility with equipment requiring this specific thread conversion. Its robust brass construction resists deformation under pressure and maintains thread integrity over repeated use. This component is an essential spare part for maintenance, repair, and operations (MRO) inventories in fabrication shops, ensuring that downtime due to incompatible fittings is minimized.
