The Fiberglass Reinforced Epoxy system consists of conduit, fittings and adaptors. It is designed to provide utilities and industry with a reliable, easily installed carrier for below ground, above ground and underwater electrical cables.FRE® conduit is available in standard diameter sizes from 3/4″ through 8″ (19 through 203 mm) in lengths of 9.84 ft (3 m) and 19.68 ft (6 m). Each length of FRE® conduit contains an integral inside tapered bell end for pushfit watertight assembly. A complete range of general purpose fittings (elbows, adaptors, caps) is available to interconnect the conduit. The fittings can be used with a wide range of conduit systems. Special purpose fittings (O’Ring expansion joint, wobble coupling) are also offered for use in conjunction with bridge installations. A selection of adaptors enables connection of FRE® conduit to threaded steel, PVC, asbestos cement and bituminous fiber systems. Where water is a problem, adhesive and splice kits are available.
