Whale Service Kit for Flipper Mk3 & Mk4 Hand Pumps
Keep your Whale Flipper hand pump in reliable working order with the genuine Whale AK0405 service kit. The Flipper is a compact, single-action hand pump designed for freshwater delivery in small boats, tenders, and sailboats where a simple, non-electric water supply is preferred. This service kit contains the wear parts needed to restore full pump performance — valves, diaphragm, and seals — so you can rebuild the pump rather than replace it. Compatible with both the Mk3 and Mk4 versions of the Flipper.
