Afdichtingsset voor giekcilinder

A boom cylinder seal kit contains replacement seals used when servicing a hydraulic boom cylinder. Worn seals can contribute to hydraulic fluid leaks. Please check the individual seal kit page for the kit’s stated contents and application, as these details can vary by product.

Our boom cylinder seal kits cover selected models from brands including Komatsu, Kobelco, John Deere, Case, Caterpillar, Hyundai, and Yanmar. For example, part number 707-99-59320 is listed for Komatsu PC270-8, PC270LC-8, PC290LC-8, and PC308USLC-3 excavators. Please use the individual listing to confirm the application for your machine.

Not unless the seal kit listing specifically confirms that application. Boom, arm, and bucket cylinders may use different seal arrangements. Please select a kit listed for the cylinder you’re repairing, and don’t rely on the excavator model alone to determine compatibility.

Please check the original part number and your machine’s serial number before ordering. Some seal kits list more than one compatible part number or specify serial-number ranges for particular applications. If the details don’t clearly match, please consult the machine’s parts documentation before placing your order.
