What is the difference between a rubber washer and a rubber gasket?
Gaskets are used to prevent leaks around mating surfaces, whereas washers are used to distribute the load of a threaded fastener. Most washers won’t have the ability to prevent fluid or gas leakage; therefore, gaskets are the better choice for sealing applications.
Can a washer be used as a gasket?
Washers are used to distribute the load of a threaded fastener, whereas gaskets are used to prevent leaks around mating surfaces. Most washers won’t prevent fluids or gases from leaking; they will only distribute the load of the fastener with which they are used. For sealing applications, you’ll need to use a gasket.
