999968 - ESAB Brass Adapter B-Size Female LH to 1/4 NPT Male

Precision Brass Adapter for Fuel Gas Systems

The ESAB 999968 is a specialized brass adapter engineered for the safe and efficient connection of oxy-fuel components. It features a B-Size (5/8"-18) Female thread on the inlet side and a 1/4" National Pipe Thread (NPT) Male on the outlet side. Crucially, the B-Size connection utilizes a Left-Hand (LH) thread pitch, adhering to CGA safety standards for acetylene and other fuel gases to prevent accidental cross-connection with oxygen lines.

Constructed from high-grade brass, this fitting offers superior resistance to corrosion and mechanical wear, making it suitable for industrial environments. It is commonly employed in the assembly of gas manifolds, the adaptation of regulators to hard-piped systems, or the conversion of pipe threads to accept standard welding hoses. The precision machining ensures a tight, leak-resistant seal when installed with appropriate gas-rated thread sealants on the NPT end.

This adapter is an indispensable component for MRO technicians and facility managers responsible for maintaining gas distribution infrastructure. Its compliance with industry thread standards ensures seamless integration with existing equipment from major manufacturers.
