OVERVIEW

Precision Brass Connection for Heavy-Duty Gas Systems

The ESAB 999605 is a specialized C-Size hose nipple designed to facilitate secure connections in high-capacity gas distribution systems. Unlike standard B-size fittings found on light-to-medium duty equipment, C-Size fittings utilize a larger 7/8"-14 thread platform, allowing for significantly higher gas flow rates required in heavy industrial cutting, heating, and manifold applications. This specific nipple is engineered to interface seamlessly with 3/8-inch Inner Diameter (I.D.) hoses, a standard size for delivering substantial volumes of oxygen, fuel gas, or shielding gas over longer distances.

Manufactured from high-grade brass, this component offers excellent resistance to corrosion and mechanical wear, essential attributes for hardware exposed to the rigors of industrial environments. The barbed end is precision-machined to provide a tight friction fit within the hose liner, which must then be secured with a crimp ferrule or a high-quality hose clamp to ensure a leak-free assembly. The sealing surface on the nipple is designed to mate perfectly with C-Size regulator outlets, torch inlets, or manifold couplers when used in conjunction with the appropriate C-Size nut (sold separately).

Proper selection of hose fittings is critical for safety and performance. Using undersized fittings in a heavy-duty setup can create flow restrictions that starve the torch or equipment, leading to instability or flashbacks. By utilizing the ESAB 999605 C-Size nipple, operators ensure that the full flow potential of their 3/8" hose is maintained right up to the connection point. This component is an essential spare part for maintenance departments and welding shops that operate heavy-duty oxy-fuel rigs or centralized gas distribution networks.

FAQ

B-Size is the standard for most general welding equipment (9/16"-18 thread), while C-Size is larger (7/8"-14 thread) and used for heavy-duty, high-flow applications.

No, this product is the nipple (stem) only. The C-Size nut must be purchased separately or reused from an existing assembly.

This nipple is designed for hose with a 3/8-inch Inner Diameter (I.D.).

Yes, the nipple itself is universal. The specific gas service is determined by the nut you pair it with (Right-Hand thread for Oxygen/Inert, Left-Hand thread for Fuel).

You must use a crimp ferrule (requires a crimping tool) or a secure hose clamp to fasten the hose to the barbed end of the nipple.

While manufactured by ESAB, it fits any standard CGA C-Size connection, making it compatible with other brands of heavy-duty equipment.

It is machined from solid brass.

C-Size fittings are required when gas flow requirements exceed 200 SCFH, common in heavy scrapping, gouging, or manifold applications.
