OVERVIEW

High-Performance Alumina TIG Nozzle for Series 8 Torches

The CK Worldwide 8A5 Alumina Cup is a premium TIG welding consumable engineered specifically for the 8 Series line of TIG torches. Designed to meet the rigorous demands of industrial welding, this #5 nozzle features a 5/16-inch (8.0mm) orifice and a compact 5/8-inch length. It serves as a direct replacement for the industry-standard part number A53N25, ensuring seamless compatibility with a variety of micro-TIG setups. Whether you are outfitting a production line or restocking a maintenance shop, the 8A5 offers the reliability and precision required for high-quality fabrication.

Constructed from high-strength alumina material, this nozzle provides significant advantages over standard ceramic cups. Alumina is characterized by its exceptional electrical insulating properties, which are vital for maintaining a focused and stable arc without the risk of arcing to the cup itself. Additionally, the material boasts high impact resistance, making it far less susceptible to cracking or chipping if dropped or subjected to mechanical stress. Its thermal conductivity is also optimized to withstand the heat cycles associated with TIG welding, ensuring a longer service life and consistent performance.

A key benefit of the CK 8A5 is its resistance to spatter build-up. In many welding environments, spatter adhesion can disrupt shielding gas flow and lead to weld defects. The smooth surface finish of this alumina cup minimizes adherence, allowing for cleaner operation and less downtime spent on maintenance. While CK Worldwide recommends these standard alumina nozzles for the majority of welding operations, they are particularly effective in open joint configurations where standard gas coverage is sufficient. For extremely confined areas, specialized extended nozzles may be required, but the 8A5 remains the standard workhorse for the 8 Series platform.

Compatibility is a cornerstone of the CK Worldwide ecosystem. The 8A5 is designed to fit a comprehensive range of 8 Series torches, including the CK24, CK24W, CK80, CK90, CK180, CWH180, and CK24W. This broad fitment makes it an essential component for welders utilizing these compact, air-cooled, and water-cooled torches. By choosing genuine CK parts, operators ensure proper thread engagement and a gas-tight seal, which is critical for preventing atmospheric contamination and achieving X-ray quality welds.

FAQ

The 8A5 fits CK Worldwide 8 Series torches, including models CK24, CK24W, CK80, CK90, CK180, CWH180, and CK24W.

The #5 cup has an orifice diameter of 5/16 inches (approximately 8.0mm).

It is manufactured from high-strength alumina ceramic, known for its electrical insulation and impact resistance.

The industry standard cross-reference number for this nozzle is A53N25.

While 8 Series torches are designed for tight spaces, this standard length cup is recommended for most general operations. Extremely confined areas might require specialized extra-long nozzles.

Alumina cups generally offer better impact resistance and are more durable than lava cups, which are often used for their high heat tolerance but can be more brittle.

This product listing is typically for a single unit (1 Per Ea), though bulk packs may be available separately.

Spatter resistance prevents metal buildup on the nozzle orifice, ensuring consistent shielding gas flow and reducing the need for frequent cleaning.
