UPVC Rubber Ring Joint Reducing Coupler for Water

Key Features

• Double socket reducing: both ends are rubber ring sockets of different diameters for concentric size reduction.
• Straight size transition: used for connecting two UPVC pipes of different diameters.
• Rubber ring seal: quick installation without solvent cement.
• Tapered flow path: gradual transition minimizes pressure loss.

Manufacturing Process

Manufactured via high-precision injection molding with uniform tapered wall thickness. Both socket ends have machined rubber ring grooves, with concentric large and small sockets.

Critical Process Parameters

• Precise machining of socket inner diameters.
• Streamlined design and wall thickness uniformity of tapered section.
• Coaxiality control of both sockets.
• Rubber ring groove dimensional accuracy.

Raw Material Characteristics

• Material Composition: UPVC, EPDM sealing rings.
• Material Properties: Consistent with series.

Typical Applications

• Straight connections at points of diameter change in water supply pipes.
• Size transition between main and branch pipelines.
• Reducing connections when equipment ports do not match pipe diameters.

Application Scenarios

• Straight sections requiring diameter change in water supply systems.
