GASKETS, Cork ZA/CAN 5247
The full description of this Gasket is as follows:
GASKETS, Cork, 1 & 55/64-inch OD, 25/32-inch ID, .031 inch thick ZA/CAN 5247
It fits between the upper face of the Insert and the back of the Microphone Cover to insulate the Insert from making any contact with the aluminum Cover that might cause the Insert to stop operating.
The attached photo shows the remains of one of these gaskets that is actually made of cork. The others I have are all either automotive gasket paper, or thin manila and one was actually made from a Canadian Armed Forces Shipping Tag, you can still read some of the sections of it on one side.
It can be a bit tricky getting this gasket to stay in place while you screw down the Cover and Rubber Gasket. I found the best way was to put everything in place and then run the four Cover Mounting Screws home about half way. Then, while pulling up on the cover with my left hand, I used a wooden toothpick through the Mouthpiece hole in the cover to move the gasket around until it was centred at the hole, lower the Cover and hold it in place while tightening the four Cover Screws. Job Done!
