21218 - ESAB PT-27 Torch Strain Relief Boot

Genuine ESAB Replacement Support Flex for PT-27

The ESAB 21218 Support Flex is a critical replacement component designed specifically for the PT-27 plasma cutting torch. In the demanding environment of industrial plasma cutting, torch assemblies are subjected to constant movement, twisting, and pulling. This support flex, often referred to as a strain relief or cable boot, serves as the protective interface between the rigid torch handle and the flexible cable assembly. Its primary function is to absorb mechanical stress, ensuring that the delicate internal wiring and gas lines are not subjected to sharp bends or excessive tension at the connection point.

Over time, the original support flex on a plasma torch can become brittle, cracked, or detached due to heat exposure, UV radiation, and general wear and tear. When this component fails, the torch leads lose their protective support, significantly increasing the risk of kinking. A kinked cable can restrict gas flow or break internal electrical conductors, leading to arc instability, overheating, or complete torch failure. By replacing a damaged support flex with this genuine ESAB part, you effectively extend the lifespan of your entire torch assembly and prevent costly downtime associated with cable repairs.

Manufactured to ESAB's exacting standards, the 21218 Support Flex is made from a high-quality, durable polymer that retains its flexibility even under rigorous working conditions. It is engineered to fit the PT-27 handle perfectly, ensuring a secure seal that also helps prevent debris and metal dust from entering the torch body. Whether you are performing routine maintenance or repairing a damaged torch, using OEM parts like the 21218 ensures compatibility and reliability that aftermarket alternatives cannot always guarantee.

Installation is straightforward, designed to slide over the cable assembly and lock into the torch handle, restoring the ergonomic feel and safety of the tool. Keeping your plasma torch in top condition is essential for precision cutting, and neglecting small components like the support flex can lead to larger issues down the line. Invest in the longevity of your equipment with this authentic ESAB replacement part.
