Dust caps for use with multiple optical fiber adapters and connectors. A first embodiment of the invention is a dust cap for use with ST adapters, ST connectors and SC connectors. The dust cap includes a sealing surface for contacting the bottom of an ST adapter for sealing the portion of the adapter containing the alignment sleeve. The dust cap also includes an opening having a reduced diameter to prevent contamination of the tip of the ferrule of an ST or SC connector. The dust cap may be formed in a duplex fashion and include a retaining strap for securing the dust cap to an ST adapter. An alternative embodiment of the invention is a dust cap having a first side for mating with either an SC or ST adapter and a second side for mating with either an SC or ST connector.
