We are passing on to you herewith a sample of jointing material manufactured by Coopers Mechanical Joints Limited. under the name of "Corok" material. It is stated that this is being used for oil and petrol joints. We cannot at the moment see an application for this, but if you think it is likely to be useful perhaps you will try it out when an opportunity occurs. E/Lid.{A. J. Lidsey} | ||
