3P8GS - CK Worldwide 3P8GS 3 Series Glass Cup, Size 8 (10-Pack)

High-Visibility TIG Consumables for Precision Applications

The CK Worldwide 3P8GS Glass Cup is a specialized TIG welding consumable designed to solve one of the most common challenges in complex fabrication: visibility. Unlike standard alumina or ceramic cups which obscure the electrode and weld pool from certain angles, this high-temperature glass cup provides a 360-degree view of the arc. This transparency is critical when welding in restricted spaces such as inside corners, deep grooves, or the interior of small-diameter piping where line-of-sight is typically compromised.

Engineered for the 3 Series torch platform, the 3P8GS is compatible with a wide range of industry-standard torches, including models 17, 18, 26, 150, 210, 300, and 510. The cup features a #8 orifice (1/2-inch diameter), offering a balanced gas coverage suitable for a variety of amperage settings and material thicknesses. With a length of 1-7/8 inches, it maintains a standard profile that integrates seamlessly into existing setups without requiring significant adjustments to the welder's technique.

Manufactured from durable borosilicate glass, these cups are capable of withstanding the high thermal cycles inherent in TIG welding. However, they require appropriate handling to maintain their clarity and structural integrity. This product is supplied in a package of 10, ensuring that professional fabricators have an adequate supply of replacements on hand for critical projects. Whether used for sanitary stainless steel piping, aerospace components, or intricate automotive fabrication, the CK 3P8GS enhances process control by allowing the operator to verify tungsten extension and arc length visually.

Technical Specifications

The 3P8GS fits securely onto compatible gas lens assemblies designed for 3 Series torches. It is essential for users to verify they have the correct O-ring and collet body configuration to accommodate the glass nozzle. By replacing opaque nozzles with this clear alternative, welders can significantly reduce rework caused by poor visibility and electrode contamination.
