High-performance double lip metal wiper seal for Caterpillar machines. Blocks dirt, mud, and moisture. Durable polyurethane construction ensures long service life in heavy-duty hydraulic systems.
The Caterpillar Double Lip Metal Wiper Seal is engineered for extreme environments. Its dual-lip design scrapes contaminants from the rod surface while retaining internal lubrication. Made from high-grade polyurethane, it withstands abrasion, UV, and mild chemicals, ensuring reliable sealing in excavators, bulldozers, and wheel loaders.
This seal operates in temperatures from -40°C to +110°C and handles pressures up to 500 psi. Designed for dynamic speeds up to 0.5 m/s, it meets ISO 6194 and DIN 3760 standards. Easy press-fit installation into the cylinder gland reduces downtime, making it a cost-effective solution for CAT hydraulic systems.This wiper seal prevents contaminants from entering hydraulic cylinders in CAT heavy machinery (excavators, bulldozers, etc.), reducing wear on rods and seals. The dual-lip design provides extra protection in mud, dust, and wet conditions, extending component life. It ensures reliable operation under high pressure and temperature extremes, minimizing maintenance costs and downtime.
