The IPEX Scepter EC55 4-inch rigid PVC conduit coupling is built for professional electricians and contractors who need a concrete- and weather-tight connection they can count on — whether they're roughing in underground runs, encasing conduit in concrete, or working through demanding outdoor environments. Engineered from high-impact PVC, the EC55 is lightweight enough to speed up installation without sacrificing the tensile strength required for long-term performance in the field. Its non-conductive construction eliminates the risk of dangerous second points of contact, while its broad chemical resistance — against acids, alkalis, and salt solutions — means it holds up in corrosive soil conditions and industrial settings alike. For contractors looking to reduce maintenance callbacks and keep their conduit systems running trouble-free for years, the EC55 is a reliable, code-compliant choice that goes in fast and stays put.
