Some autofluid patches are heat-shrink sleeves. Heat the patch uniformly to 150°C (302°F) using an induction heater. Slip it over the shaft. As it cools, it shrinks to form a molecular bond with the metal. autofluid patch
Look for the indicator arrow or laser-etched line on the autofluid patch. This must point toward the high-pressure side (the fluid you are retaining). Installing it backward will pump fluid out of the machine. Heat the patch uniformly to 150°C (302°F) using
While the upfront cost is higher than a $2 rubber O-ring, the lifecycle cost is dramatically lower. For critical assets—wind turbine pitch drives, injection molding machines, or sewage pumps—the autofluid patch is no longer a novelty; it is the industry standard. Look for the indicator arrow or laser-etched line
