The Gen II shaft seal from Lasdrop uses a ball-bearing drive system that allows the seal ring to float within the housing and keep in constant contact with the carbon graphite seal surface, making it impenetrable to water. Also, by using a spring-loaded housing instead of a bellows, the Gen II never has to have its bellows replaced (see how that works?). All units have dual water injection ports, and are available for shaft sizes ranging from 1 1/8 to 5 inches.
This Memorial Day, remember those who were lost serving our country on the high seas in the U.S. Navy aboard PT Boats. Recently we were invited out for a ride on the only operational combat-veteran PT Boat, PT 305 in New Orleans.
