Inquiry (采购产品): Cork ball with rubber layer Hello, I am looking for cork balls (4) with rubber layers for an air vent valve (vacuum breaker). This is for an old valve that we need to replace the balls inside. The original balls were made of a cork center 2.625 inches diameter covered with an inner layer of hard rubber (1/16 thk) and an outside layer of soft rubber (1/8 thk) resulting with a 3 inches ball perfectly smooth. It is basically like a baseball but without the leather liner outside plus we need to respect the original construction (ball has to float on water, not sink) Can you supply this? **** Hidden Message ***** Marc-Etienne Grenier H8S 4K8 Company: General Electric E-mail: marc-etienne.grenier@ge.com **** Hidden Message ***** marc-etienne.grenier@ge.com
