Standards for gaskets used with M20*1.5 pressure gauges
Thread Content
Is the specification for the copper gasket used with the M20*1.5 pressure gauge 18*8*2? How can I determine whether it is this size? Is there any standard that specifies the dimensions of this gasket? Thank you!
There is no standard for rectangular flat washers; the common specifications are 18*8*2, 18*8*3, 18*6*2, and 18*6*3. There are also thick pads of 4mm, 6mm, and so on. Nylon pads and PTFE pads are much better than copper pads. For instruments, copper gaskets are meant for those who suffer from constipation and hard stools. :P
