ABSTRACT:
A large-diameter PTFE seal. The lip of the seal is made from a long strip of PTFE bound together at the ends with the aid of a patching tape to form a closed loop. The loop is then flanged and placed between an inner and an outer case, together with a rubber-like gasket, and the cases are crimped together, entrapping the lip material between them.
