21960 - ESAB 21960 Ring Seal .990 OD x .780 ID (Pack of 10)

Maintain Peak Performance with Genuine ESAB Seals

In the world of industrial plasma cutting, the smallest components often play the most critical roles. The ESAB 21960 Ring Seal is a prime example of this engineering reality. Designed specifically for ESAB plasma torch assemblies, this ring seal ensures the airtight integrity required for precision cutting. When you are in the middle of a heavy fabrication project, the last thing you need is a torch malfunction caused by a worn-out gasket. By choosing genuine ESAB parts, you are investing in the reliability and longevity of your equipment.

This product comes in a convenient pack of 10, making it an ideal choice for maintenance departments and busy workshops. Having spare seals on hand means you can address wear and tear immediately during routine consumable changes, rather than waiting for a single part to arrive while your machine sits idle. The dimensions—0.990" Outer Diameter and 0.780" Inner Diameter—are manufactured to exacting tolerances, ensuring a snug fit that generic aftermarket O-rings simply cannot guarantee.

Using the correct seal is vital for safety and efficiency. A compromised seal can lead to gas leaks, which not only wastes expensive plasma gas but can also cause fluctuations in arc stability, leading to rough cuts and increased dross. In severe cases, leaks can cause internal arcing that damages the torch head itself. The ESAB 21960 is built to withstand the thermal cycles and pressures inherent in plasma cutting environments, providing a durable barrier that keeps your system running smoothly.

Whether you are operating a manual hand torch or a mechanized system, regular inspection of your O-rings and seals is a best practice that pays dividends. Replace your seals at the first sign of cracking, flattening, or brittleness. With this 10-pack of ESAB 21960 Ring Seals, you ensure that your team has the resources they need to maintain high uptime and superior cut quality, shift after shift.
