OptiSeal VSP corrosion-resistant spring-loaded PTFE seal

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

Hallite's OptiSeal VSP is a spring-loaded single-acting piston seal. It features a U-shaped seal jacket with a V-shaped corrosion-resistant metal spring integrated into its structure. When there is no load or under low pressure, it provides the necessary spring load to the seal lip, creating appropriate contact surface pressure. As the operating pressure increases, it acts on the sealing performance at high pressure by receiving system pressure in the U-shaped area. The standard material is a high-performance seal jacket material based on PTFE. It demonstrates low friction against almost all counterpart surfaces, thereby eliminating the stick-slip phenomenon. 【Features】 ■ Excellent chemical resistance, adaptable to various applications ■ Low friction eliminates stick-slip phenomenon ■ Excellent wear resistance and long lifespan ■ Suitable for a wide temperature range ■ Outstanding dynamic and static sealing characteristics of tandem lips Hallite is a group company of Michelin.
