PVC pipe straps are used to prevent distortion in long runs of conduit while still allowing for thermal expansion. High impact and high tensile strength. PVC is resistant to external corrosion and pitting and will not rust. As a building material PVC offers outstanding fire performance characteristics. Retains original properties after years of exposure to direct sunlight, heat, and extreme weather. Resistant to a wide range of chemicals such as acids, alkalis or salt solutions. Resistant to fungi, bacterial action, rodents and termites, for a long and trouble-free life. Requires solvent cement to install.
