FLEX-A-SEAL FS10090 Rotary Seal

The FLEX-A-SEAL FS10090 Rotary Seal is a size-specific shaft sealing component designed for use with a 1-1/2" hook sleeve rotary interface. Identified by the FS10090 part number, this seal provides a barrier at the rotating shaft-to-housing junction to help prevent fluid leakage in assemblies that require a hook sleeve connection. With its 1-1/2" hook sleeve geometry, the FS10090 is intended to mate precisely with the corresponding sleeve and housing features, delivering a predictable seal performance when installed in compatible equipment. This makes it a targeted replacement option for services where that exact size and interface are specified, simplifying selection and reducing the risk of mismatches in rotating assemblies. Because rotary seals like this are positioned at the shaft seal interface, correct installation and alignment are important to maintain seal integrity and minimize leakage paths. The FS10090's labeling clearly communicates its intended fit, helping technicians and purchasers verify compatibility with equipment that uses a 1-1/2" hook sleeve design. When selecting this part, ensure the mating hook sleeve and shaft arrangement correspond to the specified size to enable proper seating and sealing performance in rotating-service applications.
