Kuriyama's Tigerflex Silver Tiger STIG Series features extremely heavy duty, polyurethane-lined material handling hoses. The extra thick, abrasion-resistant polyurethane liner is designed for dry applications where severe abrasion is a factor. The multi-strand grounding wire helps prevent the build-up of static electricity for added safety and to help keep material flowing smoothly. The wire is embedded within the rigid helix to prevent contamination of transferred materials. The convoluted outer cover provides increased hose flexibility, according to the company.
