Johns Manville Zeston® 2000 and Ceel-Co® 550 Series standard gauge PVC fitting covers are manufactured from high-impact, UV-resistant, polyvinyl chloride material designed to provide abuse-resistant protection for insulated piping. Our wide range of products and accessories enable the contractor to design, fabricate and install a complete system with a quality finished appearance. When combined with JM's PVC jacketing and solvent welding adhesive or Z-tape, our PVC fitting covers form a completely sealed system that may be used for applications below ambient conditions.
