Abstract
A rotary seal machine is provided and includes a motor drive shaft which extends into and through a canister. A test seal specimen surrounds the shaft in the outer wall, and contaminant circulates through the canister for inducing leakage of the contaminant through the seal being tested. The seal and protruded shaft are visually exposed from outside the outer wall so that contaminant leakage past the seal can be visually detected.
