ABSTRACT:
A self-lubricating plug insert-type valve assembly is provided for use with inflatable articles of manufacture, such as footballs, basketballs, etc. The sealing plug through which the inflation needle is inserted is characterized by containing 3-12 parts by weight of a silicone grease for each 100 parts of rubber contained therein. Although contained as part of the rubber mix of the cured plug, the grease migrates within the plug and forms a continually renewed lubricant coating along the passage through which the needle is inserted and withdrawn.
