PKS Neoprene Covers are made to cover the plastic clamps on most external one-pump systems since 2006. They help protect the rough edges and corners of the Clamp from accidentally cutting, ripping, or putting direct pressure on your canopy when the kite is folded up.
There are a couple brands that use a LARGER one-pump hose on their valves, and therefore a larger clamp as well. Airush and Gaastra 2011 and newer are in this category, and there may be others in time. These covers may not fit around these larger clamps, so if you have questions about your kite's one-pump system and these fitting your clamps, please ask us.
