Airhead® Multi-Valve Set includes everything you need to inflate your inflatable boat, float tube, towable, and other inflatables swiftly and easily. Set consists of two Boston valves with differing bottom thread patterns and a Shrader valve with cap. The two different thread patterns help you match the right valve to your inflatable, no matter what brand it is. Boston valves feature an easy turning square base for easier operation with wet hands. The Shrader valve attachment allows you to inflate your inflatables with an air compressor at home, at a gas station or at the marina. Shrader valve attachment screws off so you can inflate the Boston valve with an AIRHEAD air pump. All components are colored bright red and green, making them easy to spot.
