There is no waste as the cartridge empties 100%and without the spring plunger, there isNO changeover mess. single hand pistol grip or 2 handled variations available Note * Pressol grease-guns are not suitable with HUGO grease cartridge thread.For compatibility with most battery grease-guns, see our 'KAJO adapter' product page.
