Eaz-Lift RV Stabilizer Jack Lube helps protect and maintain your RV's stabilizer jacks, tongue jacks, steps and more. It is ideal for helping stop rust build-up in storage. This protectant spray offers the maximum lubrication and protection of expensive stabilization mechanisms, where there is metal-on-metal friction. The lube allows the mechanism assemblies to move smoothly without gumming up or staining. This product can also be used to lubricate and help inhibit corrosion on undercarriage parts, marine fittings and trailer hitches. The spray uses PTFE moisture-displacing technology to leave a long-lasting dry, non-greasy film that coats and seals to ward off dirt and grime and help protect against rust and corrosion. This product is specially formulated to meet stringent military specifications for deterring corrosion (MIL SPEC: MIL-C-23411; MIL-C-16173D; MIL-C-22235A). The formulation does not contain any chlorinated or fluorinated solvents and is fortified with PTFE. Rated for a minimum of 336 hours of continuous salt spray and 720 hours of complete relative humidity. Size: 15 oz.
