PPR fittings are a type of plastic pipe fittings used in plumbing and water supply systems. "PPR" stands for "polypropylene random copolymer," which is a type of plastic that is durable, heat-resistant, and corrosion-resistant.

PPR fittings are designed to be used with PPR pipes, which are also made of polypropylene random copolymer. These fittings are available in a variety of shapes and sizes, including couplings, elbows, tees, end caps, and valves. They are typically joined to PPR pipes using a heat fusion technique, which creates a strong, leak-free joint.

One of the advantages of PPR fittings is their ability to withstand high temperatures and pressures, making them suitable for use in both hot and cold water systems. They are also resistant to corrosion and chemical damage, making them a long-lasting and reliable choice for plumbing applications.
