PTFE Presser Foot for Industrial Machines. Made of white PTFE (Teflon) plastic, this foot is designed for sewing materials that tend to stick to metal feet—such as leather, synthetic leather, plastic films, foam, or delicate fabrics. The non-stick surface ensures smooth gliding, prevents wrinkling, and improves stitch consistency. Compatible with single-needle industrial lockstitch machines with bottom feed, including JUKI, SIRUBA, PFAFF, BROTHER, GARUDAN, GLOBAL, and others.
