0958-0003 - Victor CGA 680 Brass Replacement Nut

Technical Overview of the Victor 0958-0003 CGA 680 Nut

The Victor 0958-0003 is a specialized brass nut designed for use with CGA 680 connections. In the industrial gas and welding sector, the Compressed Gas Association (CGA) establishes standard fittings to ensure safety and compatibility across different gas types and pressure ratings. The CGA 680 connection is specifically designated for inert gases such as Argon, Helium, and Nitrogen utilized in high-pressure environments, typically ranging from 3001 PSIG up to 5500 PSIG. This component is critical for assembling regulator inlets, pigtails, and manifold systems that interface directly with high-pressure cylinders.

Manufactured from high-quality brass, this nut offers the necessary mechanical strength to withstand the significant torque required to seat the nipple against the cylinder valve, ensuring a leak-tight seal. Brass is the material of choice for these fittings due to its non-sparking properties, corrosion resistance, and durability under thermal cycling. The precision machining of the threads ensures smooth engagement with the cylinder valve, reducing the risk of cross-threading or galling, which can compromise the integrity of the high-pressure seal.

Safety in high-pressure gas distribution is paramount. Using the correct nut and nipple combination is essential to prevent catastrophic failure. The CGA 680 standard employs a specific dimension and thread pitch that prevents the accidental connection of incompatible gases or lower-pressure equipment to a high-pressure source. The Victor 0958-0003 is an OEM replacement part, ensuring that it meets the rigorous dimensional tolerances and material specifications required by Victor equipment. It is intended to be used in conjunction with a compatible CGA 680 nipple (sold separately) to complete the connection assembly.

Industrial MRO professionals and gas system designers rely on genuine Victor components to maintain the certification and safety standards of their gas distribution infrastructure. Whether for laboratory gas delivery, laser cutting assist gas supply, or heavy industrial welding applications, this brass nut provides the reliability expected from a leading manufacturer in gas control equipment.
