Exceptional Durability. The tough, durable Zeston PVC Jacketing resists damage from impact and will withstand humidity, salt water, adverse weather conditions and most industrial fumes. In addition, the jacketing will not support combustion.

PVC Fittings

Zeston 300® Series PVC heavy duty fitting covers and Zeston PVC jacketing are specifically designed for industrial and commercial applications.

Because of their added thickness and improved thickness  distribution, they exhibit excellent impact resistance, increased durability, superior UV resistance and reduced chance of “burn through” when solvent welding.

Zeston 300 Series PVC fitting covers are produced from a white, glossy, high-impact, UV resistant polyvinyl chloride compound. Available in many shapes and sizes, they fit quickly and snugly over a variety of pipe fittings.

A variety of fitting covers and jacketing are available in color. They are recommended for indoor use only and are not UV resistant. Call for availability.

Made from the same rugged, pliable PVC material, Zeston PVC jacketing is designed to match the Zeston 300 Series fitting covers. For use over insulated pipe and bare metal, the PVC jacketing is easy to install and maintain, provides an inherent vapor retarder and will withstand water and most chemical and low-solvency washdowns.
