Abstract
To prevent corrosion and provide for better relative movement of parts which move only slightly but are exposed to extremes in ambient operating conditions, a tubular piece of plastic material, typically Polyvinylidenfluoride or a polyamide, is drawn over the inner element of a relatively slidable pair, which may, for example be a distributor shaft, the distributor breaker cam, or distributor bearing pins, to cover the surface thereof engaged in slidable contact.
