The Lisle Adapt-A-Cap, No. 81450, works with many standard fluid bottles to easily fill hard-to-reach fluids in automobiles, motorcycles, boats, RVs, and agriculture equipment. According to the company, Adapt-A-Cap eliminates the need for external pumps, hoses, or funnels to transfer fluids. Comes with three tapered urethane adapters to fit most standard quart and larger bottles, so the bottle becomes the pump. When the bottle is squeezed, internal bottle pressure forces the fluid up and out of the tube adapter. Includes three angled tubes, two extension tubes, and two pick-up tubes.
