Two elastomeric oil seal designs, one from Chicago Rawhide and the other from National Seal were bench tested in a UH-1 type main transmission at a surface speed of 9470 fpm. Five samples from each design were tested for five hours each, and one sample was tested for 150 hours. Both seal candidate designs performed as well as or better than the baseline production seal tested. Author
