200mm 8 Inch Expansion Joint Flanged Rubber Flex Connectors End Face Fully Sealed
Product Description
8inch 200mm end face fully sealed carbon steel flange single ball rubber coupling joint flexible rubber joint
Introduction of End Face Fully Sealed Rubber Joints
The KDF type large end face fully sealed rubber joint is a high-performance, multi-functional pipe connector with wide application prospects. Combining rubber elasticity with metal flange strength, it offers excellent characteristics for demanding pipeline systems.
Key Features
- High elasticity and air tightness: Effectively absorbs pipeline vibration and displacement while reducing noise transmission.
- Pressure and media resistance: High internal density withstands substantial pressure and various media including acids, alkalis, oils, hot/cold water, and compressed gases.
- Durability: Made from environmentally friendly synthetic rubber with excellent weather and radiation resistance, free from lead and toxic substances.
- Material adaptability: Available in acid-resistant, alkali-resistant, corrosion-resistant, oil-resistant, and heat-resistant variants to suit different environments.
- Easy installation: Simple to install and maintain, though care should be taken to avoid contact with sharp metal instruments.
