269-6418: Buffer Seal

A buffer seal, also known as a barrier seal, is a mechanical device designed to provide a barrier or separation between different fluid media or environments, preventing leakage and contamination. It consists of a dynamic sealing element that is positioned between two fluids or environments with different pressures, temperatures, or compositions. It serves as a barrier between them, allowing limited or controlled fluid transfer while maintaining isolation. Attributes: Designed to withstand different pressure differentials. Designed to withstand high temperatures. Minimize friction and wear, allowing smooth operation. Applications: A buffer seal is used for maintaining the reliability and efficiency of various fluid handling systems. It is extensively used in Cat® 345C, 345D, and 349E Excavators, 980G and 980H Wheel loaders, and TR35 Powertrains.
