0903-0004 - Victor B-Size Fuel Hose Nut 9/16-18 LH

Industrial Grade Fuel Hose Connection

The Victor 0903-0004 Hose Nut is a critical component for the maintenance and assembly of oxy-fuel welding and cutting hoses. Manufactured to precise tolerances, this nut is designed to secure a hose nipple to a regulator, torch handle, or machine connection. It features the industry-standard "B" size configuration with 9/16"-18 threads.

Safety is paramount in gas welding applications. This nut utilizes a Left-Hand (LH) thread, indicated by the notched hex, which is the universal standard for fuel gases such as acetylene, propane, and propylene. This design feature mechanically prevents the accidental connection of a fuel hose to an oxygen outlet, thereby mitigating the risk of hazardous cross-mixing. The nut is machined from high-quality brass, offering excellent resistance to corrosion and deformation under torque.

This component is essential for MRO (Maintenance, Repair, and Operations) professionals who fabricate custom hose lengths or repair damaged hose ends in the field. It is compatible with standard barbed hose nipples sized for 1/4" or 3/16" I.D. hose (nipple sold separately). Whether replacing a stripped nut or building a new manifold system, the Victor 0903-0004 ensures a tight, reliable seal when paired with the appropriate mating parts.
