| -2- Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}3/JH.10.6.39. (5) Neoprene is resistant to Discol. In view of the above experience we are willing to accept Neoprene assemblies provided that they are supplied with annular packing rings .020" thick to fit between the diaphragm and the pot and with this arrangement we would be willing to accept the material. They are supplying samples for test and as the matter is extremely urgent if these are satisfactory with your approval we will instruct the order office to obtain supplies.
