67pcs TIG Gas Lens Back Cap Collet Body Assorted Kit - Better Gas Flow

In this review of the 67pcs TIG Gas Lens Back Cap Collet Body Assorted Size Kit the bottom line is clear: this kit is for welders who need a wide selection of consumables to fit 17, 18 and 26 series TIG torches and want improved gas coverage without buying multiple individual parts. The reviewer found the set useful for repair and small shop work because it includes a broad range of TIG alumina nozzles, collets and collet bodies plus gas lens components that make gas flow more uniform and improve weld quality while saving shielding gas.

Key Features

• Compatibility: Fits 17 & 26 air cooled and 18 water cooled torches including Lincoln PTA, Miller DB and Weldcraft WP series, so users can swap parts across common torch models.
• Comprehensive assortment: Includes 27 ceramic alumina nozzles, 18 collets and 5 collet bodies so most common sizes are on hand without repeated trips to the supplier.
• Gas saving design: The gas lens cups and transparent shield cup help create a uniform gas flow that can reduce shielding gas use by about 30% compared to standard ceramic cups.
• Easy assembly: The clear shield cup installs simply by pushing in place for a firm, seamless fit that improves visibility and comfort during welding.
• Durable materials: Alumina nozzles and plastic insulators offer longer service life than conventional ceramics while maintaining stable shielding performance.

Who It's For

This kit is best for hobbyists, maintenance technicians and small welding shops that service or operate Lincoln PTA, Miller DB or Weldcraft WP 17/18/26 torches and want a grab-bag of parts for quick repairs and setup changes. It is also useful for welders experimenting with gas lens setups to improve weld profile and reduce gas consumption.

Those who need precisely matched OEM single-part replacements on a production line or who cannot tolerate any missing items should look elsewhere or confirm exact included part counts before purchasing, since some buyers report occasional missing pieces in mixed assortments.

Pros & Cons

Pros

• Wide selection covers many torch models and reduces downtime for replacement parts.
