Insulator Teflon 9-20 OERLIKON W000306396 — PTFE welding cable connector insulator

Teflon insulator OERLIKON W000306396 designed for 9–20 type welding cable/connectors provides reliable electrical insulation and mechanical protection at the cable-to-connector interface. Manufactured from PTFE (polytetrafluoroethylene), this insulator resists high temperatures, arc spatter and many chemicals, making it suitable for demanding welding environments and repair work on electrode leads and torch assemblies.

Advantages

The PTFE construction ensures stable dielectric properties across a wide temperature range and strong resistance to thermal degradation and chemical attack. The insulator is dimensioned for a secure fit with 9–20 style welding cables and connectors, reducing movement and wear at the connection point. Its smooth surface reduces accumulation of welding spatter and facilitates cleaning during maintenance.

Suitable for

• Repair and replacement of 9–20 type welding cable connectors
• Use in welding torches and handheld welding guns
• Fixtures and assemblies where heat-resistant electrical insulation is required
• Environments with exposure to welding spatter, flux residues or cleaning chemicals

Key specifications

• Material: PTFE (polytetrafluoroethylene) for high temperature and chemical resistance
• Compatibility: designed to fit 9–20 type welding cables and connectors
• Function: electrical insulation and mechanical protection at cable-connector interface
• Surface: smooth finish to reduce spatter adherence and ease cleaning
• Operating conditions: suitable for high-temperature welding environments and exposure to common welding chemicals

How to use

Before installation, ensure the connector and cable are clean and free of debris. Slide the PTFE insulator into position over the cable end or connector shoulder so that it fully covers the exposed insulating area. Verify the insulator is seated firmly and that the mating connector parts engage without interference. After assembly, perform a visual inspection and, if possible, a continuity and insulation resistance check to confirm correct installation.

Usage recommendations

For best service life, avoid prolonged exposure to molten metal splash and inspect the insulator regularly for signs of deformation, cracking or surface scoring. Replace the insulator if mechanical damage or compromised insulation is observed. Store spare insulators in a clean, dry environment away from direct sunlight and aggressive chemicals.
