Hydraulic Dowty Washer's, Boksburg

We supply and fit in all types of hydraulic dowty washer's for all bolts on all trucks . Dowty washers, also known as bonded seals, are used to create a leak-proof seal for bolts and screws in high-pressure hydraulic applications, such as those found on a truck.
Function: They are designed to prevent fluid leakage (like oil, fuel, or water) from bolted connections in hydraulic systems.
Structure: A dowty washer consists of a metal outer ring and an inner ring of an elastomer material, such as rubber, which are bonded together.
Mechanism: When a bolt is tightened, the elastomer material is compressed, creating a seal against the surface of the component and the bolt head, which prevents spiral leakage. They are suitable for both high and low-pressure applications.
