Inspection hatches often sit where oil, steam, or coolant can weep through small gaps. Installing Sealing Washers under each fastening bolt is a low-effort way to prevent floor-area spills and inadvertent safety zones. On turbine covers and gearbox lids, this has performed well—even during temperature surges.
To stay safe, I specify washers verified by washer manufacturers for seal durability and chemical compatibility. A 100-hour field test confirms they maintain integrity for cycles and exposure. Add routine torque checks, and you protect both operators and assets with a simple washer choice that pays dividends.
