Transmission Oil Seal
High-Performance Transmission Seals for Reliable Protection in Gearboxes and Drivetrains
Transmission oil seals are essential to a vehicle’s drivetrain, preventing fluid leakage and protecting internal parts from dirt and contamination. These seals are positioned at critical points where rotating parts, like the input and output shafts, pass through the transmission housing. At Independence Seal Company, we provide transmission oil seals designed for maximum durability and performance. Our seals feature sturdy metal casings made from 304 stainless steel or mild carbon steel (CRS). Available with various lip materials—including NBR, Viton, PTFE, HNBR, EPDM, and silicone, these precision-engineered seals offer reliable protection in even the most demanding transmission environments.

Types of Transmission Oil Seals
At Independence Seal Company, we provide the following types of transmission oil seals:
- Radial Shaft Seals: These seals are designed to protect bearings, seal lubricants, and improve the reliability of systems. These seals feature a sealing lip, dust lip, tensioning spring, and metal case. We provide radial shaft seals for large wind turbines to small, high-speed machine tools.
- Axial Shaft Seals: These components seal axially against a counterface perpendicular to the pin or shaft. Axial shaft seals can tolerate small misalignments and provide a reliable secondary seal. We can provide axial shaft seals in highly contaminated environments exposed to mud, water, soil, and sand.
Key Application Areas of Transmission Seals
Our seals find uses across applications, including:
- Automotive Transmissions: Our transmission oil seals ensure proper lubrication and prevent leaks in automatic, hybrid, and manual vehicle transmissions. These transmission seals promote smooth gear shifts, reduce wear, and extend the lifespan of transmission components.
- Heavy-Duty Equipment: Construction and agricultural machinery operate under extreme conditions, requiring robust transmission seals. We provide transmission seals that protect gearboxes and drivetrains from high pressures and harsh environments, ensuring reliable performance and minimizing downtime.
- Industrial Equipment: Gearboxes used in industrial equipment like conveyors, turbines, and pumps require reliable sealing solutions to maintain peak performance. Our transmission seals prevent lubricant loss and contamination, helping extend the life and efficiency of these critical components.
- Marine Transmissions: Marine gear systems face high loads and corrosive environments. Our seals are specifically engineered to resist saltwater and other corrosive elements, ensuring reliable operation in challenging marine conditions.
- Electric Vehicles: We provide transmission seals for EV drivetrains to enhance their efficiency and prevent leakage in electric motor assemblies.
