Replacement Ring for Presser Foot. This replacement PTFE (Teflon) ring is designed for use with the TEXI 5004 presser foot. It ensures smooth gliding over materials that tend to stick to metal feet — such as vinyl, leather, plastic films, or coated fabrics. The non-stick surface reduces friction, protects delicate textiles, and helps maintain consistent stitch quality. A practical solution for restoring the performance of TEXI 5004 without replacing the entire foot.
