Inquiry (采购产品): Squire-Cogswell air compressor I have an blower that is used for pumping air into water. It has four graphite wafers (3/16 X 1 3/4 X 1 3/4 inches) that centrifically compress air through a gap. The pump was manufactured in the late 70's and early 80's. Do you have any of the graphite wafers or a substitute material?
