D-Seal: Combined Sealing and Damping to Prevent Cavitation Damage

Improving performance and increasing application lifetime in truck engines and transmissions with an innovative new sealing product.
Engine vibrations can cause contact to vary between rounded O-Ring sealing surfaces and the housing, creating a ‘pumping’ effect and allowing fluid to bypass the seal. Gases contained in this media can expand rapidly when pressure conditions change, causing cavitation damage and leading to failure. 

D-Seal is a new dual-function sealing and damping solution that offers a more effective alternative to O-Rings for sealing hydraulic cylinders.  Replacing the O-Ring with a D-Seal maintains leak-tight contact throughout operation, stopping cavitation damage entirely and improving overall engine longevity.
