Lincoln Mity-Vac Premium Fluid Evacuator features an integrated 1.9-gallon-capacity reservoir and measures 25" tall with a 7.5" diameter, making it ideal for draining fluids from reservoirs on boats, RVs, ATVs, snowmobiles, farm equipment, or motorcycles. For superior mobility, this lightweight, portable unit creates a vacuum quickly and efficiently by means of a convenient manual pump, eliminating the need for electricity or compressed air. The fluid evacuator unit is made of durable, chemical-resistant polyethylene and features a large base with foot stabilizer, a quick-drain pour spout, and automatic overflow prevention, with accessories included for draining engine oil or transmission fluid directly through the dipstick tubes. This model evacuator has recently been enhanced to increase performance and reliability, featuring an improved lid gasket design to prevent the chance of leakage between the lid and reservoir, with an increased sealing surface area to ensure an airtight seal during vacuum and pressure applications. All six screws used to clamp the lid to the reservoir now feature new self-locking nuts to ensure that the lid remains securely clamped and wont loosen to allow vacuum or pressure leaks. In addition, the overflow shutoff valve has been redesigned to thread into the evacuator lid instead of being glued, ensuring the valve remains securely in place.
