Kalrez® bonded door seals are designed for easy installation and low particle generation. They combine a custom seal design and proprietary adhesion technology along with the excellent plasma resistance of Kalrez® Sahara™ 8085. The seal is held in a "fixed" position versus conventional O-rings thereby eliminating "rolling/twisting" during door actuation. In addition, the seal design has been optimized using finite element analysis (FEA) to minimize high concentrations of localized stresses. As a result, both particle generation and sealing performance are significantly improved versus conventional O-rings.

Features and Benefits

• Lower particle generation and extended seal life versus conventional O-rings
• Less replacement time versus O-ring seals during preventive maintenance

Typical Applications

Gate valves, slit valve doors, etc., currently employing an O-ring seal or dovetail seal.
