Oil seals (also known as shaft seals or rotary seals) are essential for preventing leakage of lubricants and blocking the entry of contaminants into machinery. Commonly found in engines, pumps, gearboxes, and hydraulic systems, they protect internal components from dust, dirt, and fluids.

Designed with flexible lips and durable casing materials, oil seals ensure consistent sealing performance even under high pressure and temperature. Their precision design reduces maintenance frequency, extends equipment lifespan, and ensures operational reliability.
