997658 - ESAB C-Size Curved Hose Nipple for 3/8 Inch ID Hose

Heavy-Duty Connection for Industrial Gas Equipment

The ESAB 997658 is a specialized Curved Nipple designed for heavy-duty oxy-fuel applications requiring C-Size connections. Unlike standard B-size fittings found on light and medium-duty equipment, C-Size fittings (typically 7/8"-14 thread) are engineered for high-flow environments and larger industrial apparatus. This specific nipple is machined to fit 3/8-inch Inner Diameter (ID) hoses, ensuring adequate gas volume for demanding cutting and heating tasks.

One of the standout features of this component is its curved geometry. In many industrial settings, hoses connected directly to regulators or machine torches can suffer from strain due to gravity or tight routing. A curved nipple acts as a strain relief, guiding the hose away from the connection point at a natural angle. This reduces the likelihood of kinking, which can restrict gas flow, and minimizes wear on the hose crimp or clamp area, ultimately extending the lifespan of your welding hose assembly.

Manufactured from high-quality brass, this ESAB nipple offers excellent resistance to corrosion and mechanical wear. It is an essential replacement part for maintaining the safety and efficiency of your gas distribution system. Whether you are repairing a heavy-duty torch or setting up a manifold system, the ESAB 997658 ensures a secure, leak-free connection when paired with the correct nut and ferrule/clamp.

Key Benefits

• High Flow Capacity: Designed for C-Size connections used in heavy industrial applications.


• Hose Protection: Curved shape prevents kinking and reduces stress on the hose interface.
