Camco's RV Slide Out Rubber Seal Conditioner, 16 Oz. helps shield and condition your RV's slide out seals. It prolongs the life of the seal by providing UV protection and decreasing friction when extending your slide out. This helps keep your slide out mechanisms move smoothly and freely. The foaming conditioner is compatible with all rubber seals and adjacent surfaces. It is safe for RV gaskets, window and door seals. It leaves a light, water-repellant film that resists corrosion-causing moisture. This specially formulated product does not contain any chlorinated or fluorinated solvents (CFCs) and meets current California VOC requirements.
