2271148 Seal-Wiper Fits Caterpillar Models

One New Aftermarket Replacement Seal-Wiper for Caterpillar (Cat) Construction Equipment

This hydraulic cylinder wiper seal (double-lip design) installs at the cylinder head and scrapes dirt, dust, and moisture off the piston rod as it retracts, preventing external contaminants from entering the hydraulic system. It is a polyurethane seal rated at 90 durometer, engineered to maintain a clean rod and extend cylinder service life across a wide range of Caterpillar equipment types including backhoe loaders, wheel tractor-scrapers, wheel skidders, track-type tractors, track-type loaders, and telescopic handlers.
