0902-0005 - Victor "B" Size Oxygen Hose Nut 9/16-18 RH

Technical Overview of the Victor 0902-0005 Oxygen Hose Nut

The Victor 0902-0005 is a precision-engineered hose nut designed specifically for oxygen gas service in industrial welding and cutting applications. Manufactured by Victor, a leader in gas equipment, this component is essential for the fabrication, repair, and maintenance of oxy-fuel hose assemblies. The nut features a standard CGA "B" size configuration, which is the industry standard for most medium to heavy-duty welding equipment in North America. The thread specification is 9/16"-18 UNF with a Right-Hand (RH) orientation, strictly adhering to safety protocols that distinguish oxygen connections from fuel gas connections (which typically use Left-Hand threads) to prevent dangerous cross-connections.

Constructed from high-grade brass, the 0902-0005 offers superior durability and resistance to deformation under torque. Brass is the material of choice for oxygen fittings due to its non-sparking properties and resistance to oxidation. This nut is designed to slide over a corresponding hose nipple (barb) before the nipple is inserted into the hose and secured with a ferrule or clamp. The internal geometry of the nut is machined to seat perfectly against the gland of the nipple, ensuring a gas-tight seal when tightened onto a regulator outlet, torch handle, or hose coupler. Proper seating is critical to prevent leaks which can lead to hazardous oxygen-enriched atmospheres.

This component is compatible with a wide range of Victor equipment as well as other brands that utilize standard B-size fittings. It is commonly used in conjunction with 1/4-inch or 3/16-inch inner diameter (I.D.) hose nipples, depending on the hose size being employed. Industrial MRO professionals rely on genuine Victor parts like the 0902-0005 to maintain the integrity of their gas distribution systems, ensuring that all connections meet the rigorous pressure and safety requirements of oxy-fuel processes.
