2029450 - ESAB Neoprene O-Ring Replacement Seal 1.176 ID

Precision Neoprene Sealing Component

The ESAB 2029450 O-Ring is a specialized sealing component engineered to meet the rigorous demands of industrial welding equipment. Manufactured from high-grade Neoprene (Polychloroprene), this O-ring provides an exceptional balance of chemical stability and physical durability. With a precise Internal Diameter (ID) of 1.176 inches and a Cross-Section (CS) thickness of 0.070 inches, it is designed to fit specific machined grooves within ESAB machinery, ensuring a tight, leak-free assembly. The material choice of Neoprene is critical; unlike natural rubber, Neoprene exhibits outstanding resistance to oils, greases, and many industrial solvents, making it ideal for environments where exposure to lubricants or coolants is common.

This O-ring features a Durometer hardness of 70A (Shore A), which is the industry standard for most static and dynamic sealing applications. A 70A hardness ensures the seal is resistant to extrusion under moderate pressure while retaining enough flexibility to conform to surface irregularities, creating an effective barrier against gas or fluid escape. Furthermore, Neoprene offers excellent resistance to ozone, sunlight, and weathering, preventing the premature cracking and degradation often seen in inferior seals. This longevity is vital for maintaining the reliability of welding power sources, wire feeders, and torch assemblies where seal failure can lead to costly downtime.

In the context of MRO (Maintenance, Repair, and Operations), using genuine OEM parts like the ESAB 2029450 ensures compatibility and performance. Generic O-rings may deviate slightly in tolerance or material composition, leading to imperfect seals or rapid failure under thermal cycling. This component is an essential spare part for technicians servicing ESAB equipment, guaranteeing that the machinery operates within its specified parameters for safety and efficiency.
