Insulator Teflon 17/18/26 OERLIKON W000306397 for welding torches

Teflon insulator OERLIKON compatible with welding torch sizes 17, 18 and 26. This insulator is made from PTFE (Teflon) to provide electrical insulation and thermal resistance between conductive parts of the torch. It is intended as a replacement or spare part for repair and maintenance of welding torches that require a heat-resistant dielectric spacer in the specified size family.

Advantages

The PTFE construction delivers low electrical conductivity and excellent thermal stability, ensuring reliable insulation under welding conditions. The component resists sticking and chemical attack, and its smooth surface reduces buildup of spatter. Designed to match the form and fit of common 17/18/26 torch assemblies, it enables straightforward replacement without alterations to the torch body.

Suitable for

• Repair of welding torches using size 17, 18 or 26 consumables
• Maintenance tasks requiring replacement of a dielectric insulator
• Stocking spare parts for service workshops and field technicians
• Applications where heat-resistant electrical insulation is required between torch components

Key specifications

• Material: PTFE (Teflon) for high thermal and chemical resistance
• Compatibility: designed for torch size standards 17, 18 and 26
• Function: electrical insulation and thermal barrier between torch parts
• Surface: smooth finish to reduce spatter adhesion
• Application environment: welding torches operating under elevated temperatures

How to use

Ensure the torch is powered off and cooled before disassembly. Remove the nozzle and retaining parts to access the existing insulator. Take out the old insulator and fit the PTFE replacement in the correct orientation so it seats firmly between the contact and nozzle components. Reassemble the torch components in reverse order and verify correct alignment before returning the torch to service. Follow the torch manufacturer's torque and assembly guidance where applicable.

Usage recommendations

Use this insulator for standard repair and maintenance; avoid exposure to open flames or prolonged temperatures exceeding the torch's normal operating range. Inspect the insulator regularly for signs of wear, cracks or deformation and replace if damaged to maintain electrical safety and consistent welding performance.
