OptiSeal VSE corrosion-resistant spring-loaded PTFE seal

OptiSeal VSE is a versatile external pressure face seal. It features low friction, excellent chemical resistance, and can be used in environments ranging from extremely low temperatures to high temperatures!

Hallite's OptiSeal VSE is a spring-loaded external pressure seal. It features a U-shaped seal jacket that incorporates a V-shaped corrosion-resistant metal spring. When there is no load or at low pressure, the spring provides the necessary load to the seal lip, creating the appropriate contact surface pressure. As the operating pressure increases, the system pressure acts on the U-shaped area, influencing the sealing performance at high pressure. The standard material is a high-performance seal jacket made from PTFE. It exhibits low friction against almost all mating surfaces, thereby eliminating stick-slip phenomena. **Features** - Easy assembly with a simple groove design - Ideal for all flange applications - Excellent chemical resistance and a wide range of temperature and pressure resistance - Low friction at low rotational speeds Hallite is a group company of Michelin.
