UPVC Repairing Coupling for Water

Key Features

• Hot tap repair: installs under pressure without water shutdown.
• Easy installation: bolt tightening for quick deployment.
• Wide applicability: fits UPVC, PE, cast iron, and other pipe materials.
• Reliable seal: high-elasticity rubber gasket.

Manufacturing Process

Housing injection molded from UPVC or formed from metal (ductile iron/stainless steel), with EPDM gasket on inner surface. Bolts are galvanized carbon steel or stainless steel.

Critical Process Parameters

• Matching accuracy between housing ID and pipe OD.
• Gasket hardness, compression set resistance, and aging resistance.
• Correlation between bolt torque and seal compression.

Raw Material Characteristics

• Material Composition: Housing: UPVC, ductile iron, or stainless steel. Gasket: EPDM.
• Material Properties: High housing strength. Gasket resists aging and water.

Typical Applications

• Emergency repair of bursts and cracks in water supply pipes.
• Permanent repair of pinholes and corrosion perforations.
• Pressurized leak sealing where water shutdown is not feasible.

Application Scenarios

• Emergency leak repair on UPVC pipes.
