Extension Housing Seal

The Extension Housing Seal (T22110A) by RICHMOND is a critical wear component designed specifically for preventing transmission fluid leakage at the extension housing, where the transmission meets the driveshaft. This seal is essential for any transmission rebuild, overhaul, or routine maintenance project, ensuring reliable long-term performance.

Engineered to withstand transmission fluid temperatures and pressures, this seal acts as a barrier against fluid loss and contamination. Its elastomer compound resists thermal degradation and fluid breakdown, preventing the hardening or shrinkage that can lead to leaks in older seals. Proper installation is crucial to avoid pinching or twisting, which can compromise the sealing surface.

Mechanics and enthusiasts working on manual or automatic transmissions will find this seal indispensable for maintaining optimal performance. Its dimensions make it suitable for tight extension housing designs found across many transmission platforms, making it a valuable addition to any toolkit.
