What is the advantage of copper washers over steel washers? It is also used as a conductor of heat and electricity. A copper frying pan, for instance, will heat up much faster than a stainless steel pan and will maintain a more uniform temperature. In operating systems that require an extensive amount of heat dissipation, a copper washer will do the trick.
What do you use a copper washer for? They’re commonly found any time a threaded fastener has to seal in a liquid; the most common example is the crush washer under the oil drain plug of most cars. Tighten the plug, the soft copper washer deforms to fill any gaps, making a liquid-tight seal.
How does a copper washer seal? Even flat copper washers will deform during tightening to create a seal. They’re made from annealed copper, which is very soft. The raised ridge just reduces the load required to initiate the seal.
