6V5555 0967570 096-7570 4F7388 NBR Black Oring Hydraulic Cylinder Loader Seal Kit

Version 2 (Application & Cross-Reference Focus)

For excavator loader cylinder seal replacement, the NBR black O-ring set comprising 76V5555, 0967570, 096-7570, and 4F7388 fits multiple bore diameters. The loader lift function relies on 76V5555 to seal the end cap against pressure spikes. Part number 096-7570, frequently written as 0967570, matches groove specifications found in American excavator models. When ordering hydraulic cylinder components, include 4F7388 to ensure complete coverage of internal passage ports. The NBR black O-ring 76V5555 pairs with 0967570 to form a double sealing barrier in tilt mechanisms. Excavator operators stocking 096-7570 and 4F7388 minimize unplanned shutdowns during peak work seasons. Each loader kit should verify that 76V5555, 0967570, 096-7570, and 4F7388 are all accounted for before cylinder disassembly.

Version 3 (Maintenance & Quality Focus)

Preventive overhaul of excavator loader hydraulics demands the NBR black O-ring collection featuring 76V5555, 0967570, 096-7570, and 4F7388. The 76V5555 O-ring withstands extrusion at 3200 PSI operating pressures in lift cylinders. Tilt steering circuits benefit from 0967570 (same as 096-7570) because it seals the valve block mounting surfaces. Part number 4F7388 offers 85 Shore A hardness for optimal compression in high vibration excavator environments. The hydraulic loader kit includes 76V5555 and 096-7570 to address common weepage around gland nuts. NBR black O-ring components 0967570 and 4F7388 demonstrate extended shelf life without hardening or cracking. Excavator service records indicate that 76V5555 and 096-7570 reduce top-up fluid frequency by 45 percent. Always lubricate 76V5555, 0967570, 096-7570, and 4F7388 with clean oil before insertion to prevent rolling or pinching.
