07000-55490 07000-15490 0700055490 0700015490 Lift Tift Steering NBR Black Oring for Hydraulic Cylinder Loader Seal Kit

Designed for reliable performance in hydraulic systems of excavators and loaders, the 07000‑55490, 07000‑15490, 0700055490, and 0700015490 series represents a complete set of high‑performance NBR black O‑rings engineered specifically for lift, tilt, and steering hydraulic cylinders. These precision‑manufactured sealing components deliver consistent compression set resistance, oil compatibility, and long service life under the continuous working pressures and dynamic movements typical of loader and excavator operations.

 

The 07000‑55490 and its standard numeric format 0700055490 are primary part numbers for the main sealing O‑rings used in the lift and tilt cylinder circuits. Built from premium grade NBR (nitrile butadiene rubber) in black, these O‑rings offer excellent resistance to hydraulic oils, lubricants, and moderate temperature variations, making them ideal for cylinders that perform repeated lifting, loading, and tilting movements. Whether used in light‑duty municipal loaders or heavy‑duty construction excavators, 07000‑55490 and 0700055490 maintain stable sealing pressure and prevent internal or external leakage that can reduce machine efficiency and cause unplanned downtime.

 

Complementing the lift and tilt sections, the 07000‑15490 and 0700015490 part numbers cover the critical steering cylinder O‑rings, which must withstand frequent angular movement, side loads, and continuous vibration. The NBR black material used in 07000‑15490 and 0700015490 provides outstanding flexibility, tear resistance, and dimensional stability, ensuring smooth steering response and stable control even during long working hours. These O‑rings are precision molded to strict tolerances, ensuring perfect fitment into cylinder grooves without twisting, pinching, or extrusion under pressure.
