Designed for reliable performance in lift, tilt, and steering hydraulic systems across heavy-duty construction and agricultural machinery, the 3G2276 (also referenced as 3G-2276) NBR Black Seal provides robust, long‑lasting sealing for excavators and loaders operating in demanding work environments. This precision‑engineered seal is manufactured from high‑grade nitrile butadiene rubber (NBR), selected for its outstanding oil resistance, abrasion resistance, and stability under typical hydraulic working pressures and temperatures.

 

The 3G2276 and 3G-2276 part numbers represent the same high‑quality component, ensuring full interchangeability and compatibility in maintenance, repair, and overhaul operations. Whether listed as 3G2276 or 3G-2276, this seal delivers consistent dimensional accuracy and surface finish, eliminating installation errors and premature failure caused by misfit or material weakness. Its black NBR construction offers excellent resistance to hydraulic oils, lubricants, and common contaminants found in loader and excavator hydraulic circuits.

 

Specifically engineered for lift, tilt, and steering hydraulic cylinders, the 3G2276 NBR Black Seal supports smooth and stable movement during loading, tilting, and steering operations. It effectively prevents internal and external fluid leakage, maintains consistent system pressure, and protects cylinder rods from wear and contamination. In daily heavy‑duty use, the 3G-2276 seal maintains flexibility and sealing integrity even under repeated mechanical stress, extending service intervals and lowering maintenance costs.
