85W43 - ESAB Neoprene O-Ring .176 ID x .070 CS

Precision Sealing for Industrial Welding Systems

The ESAB 85W43 O-Ring is a specialized sealing component engineered to meet the rigorous demands of industrial welding equipment. Manufactured from premium Neoprene (polychloroprene), this O-ring provides a balanced combination of chemical stability and mechanical toughness. Neoprene is widely selected for welding applications due to its inherent resistance to oils, greases, and various solvents, as well as its ability to withstand degradation from ozone and weathering. This ensures that the seal maintains its integrity even in shop environments where exposure to contaminants and fluctuating temperatures is common.

Dimensionally, this O-ring features an internal diameter (ID) of 0.176 inches and a cross-sectional width (CS) of 0.070 inches. These dimensions correspond to the standard AS568-008 size, making it a critical component for specific fittings within ESAB and legacy L-Tec systems. The precise molding tolerances employed by ESAB ensure that the 85W43 fits perfectly into the designated gland or groove, providing the necessary compression to establish a leak-proof barrier. Whether used in gas distribution lines to prevent shielding gas loss or in liquid cooling circuits to contain coolants, the reliability of this component is paramount for system efficiency.

Maintenance professionals understand that using genuine OEM parts like the ESAB 85W43 is essential for preserving the original performance specifications of the equipment. Generic substitutes may lack the specific material formulation or dimensional precision required, leading to premature failure or micro-leaks that can compromise weld quality. This O-ring is designed to resist compression set, meaning it retains its elastic memory over time, ensuring a consistent seal even after repeated pressure cycles. It is an indispensable spare part for preventative maintenance schedules and emergency repairs alike.

By integrating the ESAB 85W43 O-Ring into your maintenance inventory, you ensure that your welding machinery continues to operate at peak performance. Its robust Neoprene construction safeguards against the common causes of seal failure, reducing unplanned downtime and protecting sensitive internal components from exposure to external contaminants. Trust in ESAB's engineering to deliver the quality and reliability required for professional welding operations.
