17114 - CGA-520 Acetylene B-Tank Spacer Nipple

Precision Brass Spacer Nipple for Acetylene Gas Systems

The ESAB Spacer Nipple (SKU: 17114) is a critical component for professionals managing acetylene gas distribution, specifically designed for the CGA-520 connection standard. In the realm of industrial gas equipment, the integrity of every connection point is paramount to both safety and operational efficiency. This spacer nipple is engineered to facilitate secure connections between acetylene cylinders—commonly the 'B' size tanks used in plumbing, HVAC, and light fabrication—and the regulating equipment. By utilizing high-quality brass, this fitting offers the necessary ductility to create a tight metal-to-metal seal while maintaining the hardness required to resist thread deformation over repeated use.

The CGA-520 standard is specific to acetylene service for smaller cylinders, featuring a .899"-18 NGO right-hand external thread. This spacer nipple is manufactured to exact dimensional tolerances, ensuring full compatibility with standard CGA-520 nuts and regulator inlets. It serves a vital function in manifold assemblies or regulator setups where spacing adjustments are required to clear cylinder valves or other obstructions. The use of a spacer can prevent physical strain on the regulator body and the cylinder valve, thereby reducing the risk of mechanical failure or gas leaks. In complex piping and fitting environments, having the correct spacer ensures that equipment sits at the optimal angle for gauge visibility and hose routing.

Safety in oxy-fuel applications cannot be overstated. Acetylene is a volatile gas, and the fittings used to control it must meet rigorous standards. This ESAB component undergoes strict quality control to ensure it is free from burrs, cracks, or machining imperfections that could compromise the seal. The brass construction is naturally spark-resistant, a non-negotiable feature for components used in flammable gas service. Whether you are maintaining a fleet of portable torch kits or configuring a custom gas manifold in a workshop, this spacer nipple provides the reliability and precision demanded by industrial safety protocols.

Integration of this spacer nipple into your inventory management for gas apparatus parts ensures that your maintenance teams have the right hardware to address connection geometry issues immediately. It is a simple yet indispensable part for maintaining the functionality and safety of acetylene delivery systems.
