Quad-Ring® Seal-Glide® I (Industrial) is a PTFE-based thin-film coating applied to elastomer Quad-Ring®, enhancing their dynamic performance in industrial sealing applications. By combining elastomer flexibility with advanced PTFE-film lubrication, the Seal-Glide® I coating provides a simple upgrade path for Quad-Ring® performance, especially in applications suffering from stick-slip, high friction startup, or premature wear, all while preserving existing hardware design.
