74S76 - Brass Adapter 1/4 NPT Male to 5/8-18 Female Inert Gas

Precision Brass Adapter for Inert Gas Systems

The Western Enterprises 74S-76 is a high-quality brass adapter designed to facilitate secure connections in industrial gas systems. Engineered with precision, this fitting features a 1/4-inch NPT Male thread on one end and a 5/8-inch - 18 Right Hand Female thread on the other. This specific configuration is tailored for Inert Gas applications, commonly referred to as "B-Size" connections in the welding and industrial gas industry.

Manufactured from solid brass, the 74S-76 offers superior durability and resistance to corrosion, making it suitable for long-term use in shop environments. The NPT (National Pipe Taper) thread ensures a tight seal when used with appropriate thread sealant, while the 5/8"-18 thread is the standard interface for many argon, helium, and nitrogen regulators and hoses. This adapter is an essential component for technicians building custom manifolds, repairing equipment, or adapting regulators to different port sizes.

Reliability is paramount in gas distribution. Western Enterprises fittings are known for their consistent machining tolerances, ensuring that threads engage smoothly and seat properly to prevent leaks. Whether you are setting up a TIG welding station or a purging system, this adapter provides the necessary interface to connect your equipment safely and efficiently.
