41V33 - 41V33 Short Back Cap for WP-9 & WP-20 TIG Torches

Precision TIG Torch Component for Confined Spaces

The Generic 41V33 Short Back Cap is an essential consumable designed to enhance the versatility of 9 Series (air-cooled) and 20 Series (water-cooled) TIG welding torches. Engineered to meet or exceed industrial standards, this back cap serves a critical function in the TIG assembly by applying necessary pressure to the collet, securing the tungsten electrode in place while creating an airtight seal against the torch body. Its primary distinction is its compact, low-profile geometry, which drastically reduces the overall length of the torch head assembly. This reduction in size is indispensable for welders operating in restricted environments, such as pipe clusters, internal corners, or automotive exhaust fabrication, where standard long back caps would obstruct access.

Manufactured from high-grade, heat-resistant phenolic materials, the 41V33 replacement cap is built to withstand the intense thermal cycling inherent in TIG welding processes. The material resists cracking and deformation even under prolonged exposure to reflected arc heat. The unit comes complete with a pre-installed, high-quality O-ring that ensures a positive gas seal, preventing atmospheric contamination of the shield gas stream—a common cause of porosity and weld defects. This component is fully compatible with major torch brands including Weldcraft, Miller, Lincoln, CK Worldwide, and other IEC standard 9/20 series torches.

In industrial maintenance and repair operations (MRO), having a reliable supply of back caps is crucial. Threads can become stripped over time, and O-rings eventually degrade due to heat and ozone exposure. This generic equivalent offers a cost-efficient solution for stocking tool cribs and welding carts, ensuring that production downtime is minimized. Whether used for intricate aerospace work or general light-duty fabrication, this short back cap provides the secure fit and reliable performance professional welders demand.
