Chemtrol® PP fittings are lightweight, easy to install and maintenance-free. The fittings join piping lengths together with thermo-seal fusion, threading or flanging. Please refer to Chemtrol technical data sheets, chemical resistance guides and catalogs for engineering and installation information. Chemtrol® industrial thermoplastic flow-control systems perform well in harsh environments because they are made with materials that are resistant to abrasion, corrosion, weather, chemical andmore biological attack. Chemtrol® black polypropylene demonstrates excellent tensile strength, UV stability and versatile chemical resistance properties, making it the material of choice for harsh industrial, outdoor and underground applications. less
