Leemco Restrained fittings are designed to get a system in operation in the least amount of time and effort. All changes of directions and reductions are mechanically restrained. Additional adjacent joints shall are also restrained. Leemco Self-Restrained fittings have blunt cast serrations which are specifically designed for PVC or HDPE plastic pipe. These non-machined serrations will not damage the plastic pipe surface and have a fused epoxy finish to protect against corrosive soil conditions. Its patented bell design incorporates a cast-on half clamp and a detachable clamp, plus an easy-to-install, proven 2-bolt system that saves time and labor costs.
