L7414 COPY. Re Washers for Air Valves. X.705. With reference to the washers under the air valve, originally I put on the fibre washer, so that the air valve could be tightened down without seizing, which might have been the case if we had used no washer at all. The fact of it being somewhat spongy and elastic should prevent it working loose, and I quite think with Mr. Hives that the fitting is better as it is. You might, however, try an ebonite washer to see whether the peculiarity of the ebonite would be any advantage. I do not think it would, as I fear the heat might make it flow.
