0004485671 - ESAB Replacement O-Ring 0.364 ID x 0.070 CS (Pack of 10)

Technical Overview of the ESAB 0004485671 O-Ring

The ESAB 0004485671 is a precision-engineered O-ring designed to serve as a critical sealing component within specific ESAB welding systems. This product is supplied in a pack of ten, facilitating routine maintenance and inventory management for industrial repair operations. The O-ring features an Inner Diameter (ID) of 0.364 inches and a Cross-Section (CS) diameter of 0.070 inches. These dimensions are manufactured to tight tolerances to ensure a correct interference fit within the mating gland, which is essential for preventing the bypass of gases or fluids under pressure.

The material composition of this O-ring is denoted as "CR," which stands for Chloroprene Rubber, commonly known by the trade name Neoprene. Chloroprene is selected for this application due to its well-balanced chemical and physical properties. Unlike natural rubber, CR exhibits superior resistance to degradation from ozone, sunlight, and oxidation, making it suitable for equipment that may be exposed to varying environmental conditions in a workshop. Furthermore, Chloroprene provides moderate resistance to petroleum-based oils and fuels, which is advantageous if the O-ring is located near lubricated mechanical parts or hydraulic systems. Its operating temperature range typically spans from approximately -40°F to +250°F, allowing it to maintain elasticity and sealing capability in the thermal environments often associated with welding machinery.

In the context of welding equipment maintenance, the integrity of O-rings is paramount. A compromised seal can lead to shielding gas leaks, which results in porosity in the weld metal, or coolant leaks in water-cooled systems, potentially causing overheating and torch failure. The 0.070-inch cross-section of this O-ring provides the necessary squeeze to accommodate surface irregularities between mating parts while maintaining a robust seal. By utilizing genuine OEM parts like the ESAB 0004485671, technicians ensure that the durometer (hardness) and dimensional stability of the replacement part match the original engineering specifications of the machine, thereby preserving the equipment's reliability and performance standards.
