Compatible with a wide range of inflatables: designed for use with kayaks, inflatable boats and paddle boards so you do not need multiple adapters or different tools. Universal pump compatibility: works reliably with electric pumps, hand pumps and foot pumps for fast, flexible inflation and deflation. Secure, leakresistant seal: the air valve covers use a sealed design that provides leakproof performance, reducing air loss during use and storage. Durable ABS construction: made from strength, wearresistant ABS material that holds its shape, resists deformation and stands up to repeated use. Practical and spacesaving: replaces the need to carry different inflatable tools or multiple valve types, simplifying packing for outdoor activities. Easy to use: straightforward fit and operation with standard inflatable valve connections for quick setup on the water or at the trailhead. Use scenarios Weekend kayaking trip: attach the transfer valve to your kayak and use an electric pump at the car or a hand pump onsite to inflate quickly and reliably.
