Seal Replacement
Seal replacement is a crucial maintenance task in industrial equipment repair where technicians replace worn-out seals that prevent leaks in machinery. Seals are protective components that keep fluids, gases, or lubricants where they should be and prevent contamination. This work is essential across many industries, from manufacturing plants to food processing facilities. When someone lists seal replacement on their resume, they're showing they can identify failing seals, safely remove old ones, and install new ones to keep equipment running properly. This task requires attention to detail and understanding of different seal types like mechanical seals, O-rings, and gaskets.
