Spring Energized Lip Seals The DXTSEALS spring-energized PTFE seal represents the latest generation of spring-activated Teflon seals. These seals feature a specialized precision jacket/lip crafted from Teflon (or other high-performance polymers) and a corrosion-resistant stainless steel spring. This unique combination allows the spring to press the seal lips against the gland and rod walls, with the pressure further assisting the spring force. The spring adjusts for lip wear, hardware tolerances, and eccentricities, providing continuous resilience to the seal lips. The DXTSEALS design, with its sealing lip and spring arrangement, offers superior leakage protection compared to traditional lip seals. Benefits Chemical resistance against almost all medias Temperature -250�°C to +300�°C Low friction coefficient No stick-slip-effect Diameter range from 2 mm to 3000 mm Radial Seals Apart from the standard shapes listed below, we develop variants customized to the respective application. Our technical department will be pleased to advise you. PTFE Seal Operation Range The extensive range of options ensures that all radial seals' sealing requirements can be met. It's important to note that not all maximum stresses can be simultaneously applied to the seal. With a variety of designs, jacket and spring materials, and different dimensions, these seals can be used in a wide range of working conditions, including: Temperature range from -250�°C to +316�°C Suitable for rotation and reciprocating movements up to 5 m/s Static applications with pressures up to 3500 bar Dynamic applications with pressures up to 550 bar Universally resistant to chemicals Available in diameters ranging from 2 mm to 3000 mm.
