O-Ring 9921338 is used on selected Hiab equipment to provide sealing within hydraulic or mechanical assemblies. O-Rings are fitted between mating components to prevent oil leaks and maintain correct system pressure. They are commonly used in hydraulic valves, fittings, cylinders and other sealed connections throughout the crane. Over time, o-rings can harden, crack or become damaged due to heat, pressure and contamination. Replacing worn seals with the correct Hiab part number helps maintain leak free operation and protect the hydraulic system. Compatibility Part number 9921338 is fitted to selected Hiab machines. Suitability depends on the crane model and serial number. If you are unsure whether this o-ring is correct for your equipment, contact us with the serial number and we will confirm compatibility before you order. Only commonly used parts are listed on our website. We can supply any Hiab parts UK customers require, including model specific seals and service components identified by part number. If you cannot find the part you need, contact us with the serial number of your crane and details of the part required and we will help identify the correct item.
