Key Features

90° Bend Structure - The fitting enables right-angle direction changes in pipeline routing. The HDPE Compression Elbow 90° provides this core function reliably.
Quick Push-fit Locking - Stainless steel claws and EPDM seal ring lock and seal the pipe end by hand, no fusion equipment required.
Independent End Sealing - Each end has its own clamps and seal ring, allowing staged installation and pressure testing.
Corrosion-resistant PP Body - Hygienic polypropylene body suits potable and irrigation water, resisting chemical corrosion and scaling.
Reusable Design - The HDPE Compression Elbow 90° can be loosened and reassembled for maintenance or retrofit without cutting the pipe.
ISO 14236 Certified - Compliant with international standards for water supply systems, ensuring quality and reliability.

Production

Raw Material

The HDPE Compression Elbow 90° body is injection-molded from PPR (polypropylene random copolymer) for high stiffness, creep resistance, and long-term service temperature up to 70°C. The seal ring is EPDM rubber for potable water compliance. The gripping claws are 304 stainless steel for corrosion resistance and clamping force retention.

Molding Process

The PP body is produced by precision injection molding with controlled temperature, pressure, and cooling rate to ensure dimensional stability of the gripping surface and seal-ring groove concentricity. Wall-thickness uniformity is monitored to guarantee pressure rating. The stainless steel claw is stamped and heat-treated to maintain spring force over repeated installation cycles.

Quality Control

Every HDPE Compression Elbow 90° undergoes 100% pneumatic leak test at 1.5x rated pressure, sampling hydrostatic strength test at 2x rated pressure for 1 hour, and dimensional inspection of gripping surface, seal-ring groove concentricity, and wall thickness uniformity. Batch records are retained for 3 years traceability.

Applications

Water Supply Networks - The HDPE Compression Elbow 90° is used in residential and commercial HDPE water distribution systems for reliable leak-free connections.
Irrigation Systems - Connecting PE irrigation mainlines and sub-mainlines in farmland, orchards, and greenhouse installations.
Drainage Systems - In-line coupling of HDPE drainage and sewer pipelines for underground service without fusion equipment.
Industrial Cooling Water - Joining HDPE cooling water lines in industrial plants where chemical resistance and quick installation are priorities.
Retrofit and Maintenance - The reusable HDPE Compression Elbow 90° allows quick pipe extension, repair, or valve insertion without shutting down the whole line.
