20K Duo Seal
The Chesterton 20K Duo Seal is a heavy-duty, bi-directional sealing solution for high-pressure hydraulic rod and piston applications. Its continuous, dual-lip design eliminates the need for multi-piece cap seals, offering strong extrusion resistance and reliable performance in extreme conditions. This metal-free seal is built to handle pressure spikes and mechanical shock, making it ideal for demanding industrial environments.
Engineered from durable polymer materials, the 20K Duo Seal operates across a broad temperature range and maintains sealing integrity at speeds up to 0.9 meters per second. Its one-piece construction simplifies installation and reduces the risk of leakage, providing long-lasting protection and improved equipment reliability.
