1539053 1328816 CYLINDER SEAL KIT HYDRAULIC SEAL KIT

What distinguishes the 1539053 kit is its multi-material sealing system. It features wear-resistant polyurethane primary seals that excel in dynamic applications, paired with PTFE guide rings to reduce friction and prevent metal-to-metal contact. Additionally, nitrile O-rings provide secondary sealing against fluid leakage, while dust wiper rings keep contaminants like dirt, sand, and moisture out of the cylinder—critical for prolonging the life of excavator boom cylinders and loader lift cylinders.
