Trelleborg Sealing Solutions” Turcon Variseal PS is a PEEK-energized seal with low leach-out in semiconductor wet processing applications. The seal is an all-polymer product with no metallic components. A further development of the traditional metallic spring-energized Turcon Variseal, the Variseal PS uses a Turcon jacket to maintain its ability to seal with the sealing load applied through the use of PEEK polymer. The seal operates at temperatures up to 176 F/ 80 C. It is resistant to virtually all chemicals and withstands pressures up to 5,800 PSI/ 400 Bar. It is available in sizes from 0.020 in/ 3mm to 90 in/ 2.3m for fitment in custom or standard o-ring grooves.
