Wave-Spülmaschine von De Dietrich 7774102

A wave washer is a spring-like fastener that provides preload and prevents loosening of bolted joints in boilers and burners due to vibration or thermal expansion. This small but important part helps maintain consistent clamping force, reducing the risk of leaks or component movement. When replacing wave washers, choose the correct size and material for your application to ensure effective locking. They are often used in conjunction with screws or bolts in heating equipment assemblies.
