8693 - Western Enterprises 8693 Acetylene Adapter - 1/2" NPT Male x B-Size LH Male

Precision Brass Adapter for Acetylene Manifolds and Piping

The Western Enterprises 8693 is a specialized brass adapter designed to facilitate secure connections within industrial gas distribution systems. Specifically engineered for Acetylene and other fuel gases, this fitting serves as a critical interface between rigid piping infrastructure and flexible delivery equipment. The adapter features a 1/2-inch National Pipe Thread (NPT) Male connection on one end and a standard B-Size (9/16"-18) Left-Hand Male connection on the other. This configuration is commonly utilized in station drops, manifold outlets, and regulator setups where a transition from permanent piping to a standard hose connection is required.

Manufactured from high-quality brass, the 8693 adapter offers superior resistance to corrosion and mechanical wear, ensuring a long service life even in demanding industrial environments. Brass is the material of choice for fuel gas fittings due to its non-sparking properties, which is a critical safety factor when handling volatile gases like acetylene. The precision machining of the threads ensures a tight, leak-proof seal when installed correctly with appropriate thread sealants (for the NPT side) and mechanical seating (for the B-Size side).

Safety is paramount in gas welding applications, and the 8693 incorporates standard safety features to prevent cross-connections. The B-Size connection utilizes Left-Hand (LH) threads, indicated by the notch on the hex nut (if applicable) or standard industry coding. This prevents the accidental connection of oxygen hoses or equipment to the fuel gas line, a vital precaution against fire and explosion hazards. This adapter is fully compliant with Compressed Gas Association (CGA) standards for dimension and safety.

Whether you are outfitting a new welding shop with station drops or performing maintenance on an existing manifold system, the Western Enterprises 8693 provides the reliability and compatibility needed for professional gas management. Its robust design handles the standard working pressures of acetylene systems while maintaining structural integrity.
