They provide a convenient and reliable method for joining pipes without the need for specialized tools or equipment. These fittings are typically made from high-quality polypropylene material, known for its durability, chemical resistance, and excellent seal performance under pressure. For many years, PP compression fittings have been widely used in agricultural system, drinking water supply and other pipeline systems. The overall demand in the global corresponding market is large and increasing year by year.
