Why are copper washers required on banjo fittings?
I’m assuming that copper is a softer metal than bronze, brass or steel so they will squish when torqued to make a seal. However, I’ve seen copper crush washers that had an embossed ring in the center of the washer that would actually crush down when under pressure.
When do you use a crush washer in a car?
Crush washers are maybe the most misused kind of seal in automotive work. 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.
Do you need a crush washer for an oil change?
The usual response to this is to crank down on whatever it’s sealing to try to stop the leak. In the case of the oil drain plug, this usually results in stripping out the threads in the oil pan. Most parts stores have a rack of oil pan crush washers of various sizes; they’re cheap, and should be replaced with every oil change.
Do the flat copper washers work in the same way?
Do the flat copper washers work in the same way? You are correct that the copper washer is required to create a 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.
What can you do with a brass washer?
Use them to create a way to run rope and cable through tarps, covers, and curtains. A rolled rim provides added grip while the elongated neck and teeth on the washer, also known as a spur washer, add reinforcement and reduce rotation so you can use these grommets in thick materials such as canvas. Press the grommets into a hole you’ve already cut.
Is it possible to reuse a crush washer?
I have been reusing crush washers for years. The trick to reusing them is you need to remove the distortion they have when they were crushed on to your part. This distortion is what makes crush washers so effective. If you try putting a crush washer back on without taking the distortion out, there’s a good chance it will leak.
