Solid Sleeve Connections

Solid sleeves are ductile iron fittings designed to connect DI/PVC pipe to other piping materials, including PE pipe, and are available in a variety of configurations depending on the application. Most solid sleeves have a flange or other mechanical joint (MJ) to attach to the PE pipe. On the ductile iron pipe side, a Megalug flange is attached to the pipe and a gasket is installed over the pipe and into the sleeve before bolting the Megalug to the Sleeve flange. A standard polyethylene MJ adapter is fused to the PE pipe side to complete the assembly.
