The JACKSON SAFETY 16642 is a replacement light seal gasket designed for use with the Jackson Safety HSL100 passive welding helmet. The gasket creates a seal between the helmet shell and the lens assembly, preventing light leaks around the viewing area during welding operations. Maintaining an intact light seal is essential for arc flash protection and proper shading performance. This is an OEM-style replacement component intended for field servicing of the HSL100 helmet, installed by welders or safety equipment technicians when the original gasket shows wear or damage.
This gasket is sold as a replacement part for the Jackson Safety HSL100 passive welding helmet, sold separately. It is suited for MIG, TIG, stick, and general arc welding applications in fabrication shops, construction sites, and industrial maintenance environments where the HSL100 helmet is in service. Keeping a supply of replacement gaskets on hand minimizes downtime when helmets require routine maintenance.
Compatible with the Jackson Safety HSL100 Passive Welding Helmet, sold separately.
Installation should be performed by a qualified welder or safety equipment technician familiar with the helmet model. Remove the lens assembly from the helmet shell before replacing the gasket, following the helmet manufacturer's service instructions. Ensure the new gasket seats fully and evenly before reassembling the lens to avoid gaps that could allow light infiltration. Inspect the completed assembly for proper fit before returning the helmet to service.
