Inquiry (采购产品): O-rings We currently use Buna-N metric o-rings to seal the handles on our nylon ball valves. We use sizes 18x3, 30x4 & 41x4. The handles are quite hard to turn. Rather than trying expensive modifications of our molds, we would like to try using softer o-rings. Can you supply a minimum quantity of each size in 40A and 50A durometers? Please quote and experimental quantity and price for each size as well as production quantities. **** Hidden Message ***** Robert Foresman 92688 Company: Forespar Products Corp E-mail: robertf150@sbcglobal.net **** Hidden Message ***** robertf150@sbcglobal.net
