CPVC Backing Ring
The CPVC Backing Ring is a precision-molded component used in conjunction with stub ends or flanged joints in piping systems to ensure a secure, even distribution of clamping force and effective sealing. Manufactured from Chlorinated Polyvinyl Chloride (CPVC), these backing rings offer excellent resistance to corrosion, high temperatures, and chemical exposure. They are commonly used in industrial, chemical, and water treatment applications where flanged connections are required for easy disassembly and maintenance.

Key Feature of CPVC Backing Ring
- High Chemical Resistance: Inert to a wide range of corrosive chemicals, making it ideal for aggressive environments.
- Thermal Stability: Can withstand continuous operating temperatures up to 93°C (200°F).
- Corrosion-Free: Unlike metal rings, CPVC backing rings will not rust or corrode, even in moist or chemically reactive conditions.
- Lightweight and Durable: Offers mechanical strength while being easier to handle and install compared to metal alternatives.
- Smooth Surface Finish: Provides consistent pressure distribution and sealing with minimal surface friction.
- UV and Weather Resistant: Suitable for use in both indoor and protected outdoor installations.
- Compatible Design: Works seamlessly with CPVC stub ends and flanged fittings for reliable joint assembly.
