Legacy/Karcher/Shark/Hotsy Pump Repair Parts Chart

These Pumps were manufactured with "V" Seals until 2009, at which time Karcher/Hotsy introduced "NESTechnology" which stands for Nested Seal Technology, also known as "U" Seals. U Seals and V Seals ARE NOT INTERCHANGEABLE, so please be certain which type of seals your pump uses prior to purchasing from the table below.
