Our lightweight double wall used oil and antifreeze evacuation packages come completely assembled and ready for use. Connect the pump air supply hose and you are ready for use. These packages also include a high level pump shut off that disables the pump should the tank become full and also a sight gauge for visual reading of the tank level. A y-strainer is included to protect the pump from debris commonly found in used fluid applications. The used oil packages come with a 1” cam lock connector and the used anti-freeze packages come with a ¾” cam lock to prevent accidental contamination of fluids.
