Product Introduction
High quality blue PPR 90° reducing elbows are used to connect pipes of different diameters and create 90° bends in piping systems. They are commonly used in cold water, hot water, heating, air conditioning, water treatment, and purified water distribution systems.
Product Advantages
High Pressure Capacity
Made from high-molecular-weight PPR Type 3 material, they can withstand pressures up to 2.5 MPa.
High Dimensional Precision
Utilizing CNC precision molds and a fully automated injection molding process, dimensional tolerances are less than 0.1 mm.
Hygienic and Safe
Complies with GB/T 18742 and ISO 15874 drinking water hygiene standards, non-toxic and odorless.

Professional Installation Guide
1. Size Check
Ensure both socket sizes match the pipe diameters. The larger side has extra rings for easy identification.
2. Heating
Heat the larger pipe end first, then the smaller one, following the proper heating time for each size.
3. Connection
Insert both pipes into the elbow in one smooth motion until they reach the stops.
4. Alignment
Confirm the 90° angle and check that both pipes are fully seated using the molded alignment marks.
5. Cooling
Hold the joint steady for at least one minute to cool naturally and prevent stress on the welds.
