20KD Face and Static Seals
The Chesterton 20KD is a continuous compression D-ring seal designed to replace traditional face seals and O-rings in static hydraulic and pneumatic applications. Engineered for high-pressure environments, it offers excellent wear and extrusion resistance, making it a dependable choice for long-term sealing performance.
Available in standard and custom sizes to fit ISO and DIN specifications, the 20KD maintains sealing integrity with minimal compression set. Ideal for valve assemblies, flanges, and control systems, this seal helps reduce leakage, extend service life, and lower maintenance demands in both general-purpose and heavy-duty applications.
