Industrial Seal Solution
To test CinchSeal, the customer installed a 7550 CinchSeal and purged it with 5 PSI of plant air on only one shaft. The CinchSeal showed virtually no leakage and has had no bearing failures since installation. They have since changed the other shaft over to rotary seals from CinchSeal as well.
