Why gamble with seals? Our solid PTFE manlid seals never fail.

February 24, 2026

PTFE seals, once sidelined in the 1950s and 1960s due to misconceptions about their properties, are experiencing a resurgence in popularity thanks to modern advancements. Early formulations of pure PTFE were misunderstood, leading engineers to overlook critical characteristics such as cold flow, high thermal expansion, and a lack of elastic memory. These traits caused PTFE to deform under stress, resulting in leaks and a reputation for unreliability when compared to traditional rubber seals. The high thermal expansion of PTFE also posed challenges in fluctuating temperatures, while its inability to adapt to pressure changes further hindered its performance. Consequently, engineers gravitated towards more forgiving materials like synthetic rubbers. However, recent innovations, including filled PTFE grades and the integration of spring energizers, have restored PTFE's standing as a dependable sealing solution in demanding applications. Recognizing these historical challenges is essential for selecting appropriate materials today, highlighting that successful engineering hinges on a thorough understanding of material limitations and the implementation of effective design solutions.
