Wiper Rods

Caterpillar Wiper Rods Keep Your Cylinders Clean and Protected

Caterpillar wiper rods sometimes called wiper seals are essential for maintaining the health and performance of your hydraulic cylinders. As the name suggests, these components wipe away dirt, dust, and debris from the cylinder rod as it moves in and out, preventing contaminants from entering the hydraulic system. This helps to minimize wear on internal seals, extend the life of cylinder components, and avoid costly repairs and downtime.

Caterpillar wiper rods are made from durable, abrasion-resistant materials like urethane or high-temperature rubber, ensuring reliable performance even in harsh environments. They are available in various sizes and configurations to fit specific machine models, and are easy to replace during regular maintenance. By keeping your cylinder rods clean and preventing contamination, wiper rods help maintain hydraulic efficiency, protect sensitive components, and preserve your investment in Caterpillar equipment.

Propel Parts offers a wide selection of high quality replacement wiper rods and wiper seals that meet OEM specifications for CAT equipment. Our online catalog makes it easy to find the right wiper for your specific machine, so you can keep your cylinders operating smoothly for years.

The main function of the Wiper Rod is to keep the rod and cylinder clean and free from foreign matter; thus preventing premature failure. Our Wiper Rods are not pressure sealing elements, yet they avoid possible abrasive effects which may result if any debris were to reach the sealing and rod bearing elements.
