PPR (Polypropylene Random Copolymer) is a plastic material used in plumbing and water supply systems. The R elbow 40*32 mm is a specific type of PPR fitting used for changing the direction of PPR pipes in a water supply system.

The R elbow 40*32 mm is a PPR fitting that has a female socket with a diameter of 40 mm on one end and a smaller female socket with a diameter of 32 mm on the other end, forming a 90-degree angle. It is designed to change the direction of the PPR pipe.

The R elbow 40*32 mm is lightweight, easy to install, and has excellent resistance to high temperatures, pressure, and chemicals. It is also corrosion-resistant and has a long lifespan.

The R elbow 40*32 mm is typically used in water supply systems to change the direction of PPR pipes, allowing the plumbing system to be installed around obstacles or change direction in the piping layout. It is commonly used in residential and commercial plumbing applications, such as in homes, hospitals, schools, and office buildings.
