3SG8 - CK Worldwide 3SG8 Silicone Nitride TIG Nozzle Size 8

Extreme Heat Resistance with Silicone Nitride

The CK 3SG8 Super Cup represents a significant leap forward in TIG welding consumable technology. Unlike standard alumina oxide nozzles (commonly pink in color), this high-performance cup is manufactured from premium Silicone Nitride (gray in color). This advanced material is engineered specifically to address the common failure points of traditional nozzles in high-demand environments. By reducing thermal conductivity by approximately 40%, the Super Cup effectively insulates the torch head while maintaining its own structural integrity under extreme thermal stress.

For professional fabricators, the most frustrating aspect of high-amperage TIG welding—particularly on aluminum with AC current—is the tendency for ceramic cups to crack due to thermal shock or reflective heat. The CK 3SG8 eliminates this issue for the vast majority of applications. Its superior material properties allow it to withstand rapid temperature changes and prolonged exposure to high-reflective heat without fracturing. This durability translates directly to the bottom line: fewer cup replacements means less downtime and lower long-term consumable costs.

This specific nozzle is a Size #8 (1/2" orifice) and measures 1-5/8" in length, offering excellent gas coverage for medium-to-heavy duty welds. It is designed as part of the 3 Series, making it fully compatible with industry-standard torch models including the 17, 18, 26, CS300, and CK510. Whether you are working in aerospace, motorsports fabrication, or heavy industrial repair, the CK 3SG8 Super Cup provides the reliability required for precision welding.

Compatibility and Performance

The 3SG8 is designed to fit seamlessly onto standard collet bodies and gas lenses for 3 Series torches. It does not require special adapters, allowing welders to upgrade their existing setup instantly. The gray Silicone Nitride material is easily distinguishable from standard parts, ensuring you know when you have the high-performance option installed. By choosing CK Worldwide's Super Cup, you are investing in a product that resists erosion and maintains a consistent gas flow pattern longer than conventional alternatives.
