PTFE Rubber Pipe Joint DN32mm-DN1200mm Rubber Bellows Expansion Joints
High-quality PTFE pipe rubber joints connecting pipe fittings flanges soft connections expanded rubber joints
Product Introduction
The PTFE rubber joint model features a PTFE lining inside the rubber ball, combining the flexibility of rubber with PTFE's superior properties. This design offers exceptional temperature resistance (+250°C to -180°C), corrosion resistance, friction resistance, shock absorption, and noise reduction capabilities, making it ideal for various pipeline applications.
Product Structure Composition
- Rubber Body: Constructed from various rubber materials (natural rubber, EPDM, nitrile, etc.) selected for specific environmental and media resistance properties.
- Lined PTFE: Polytetrafluoroethylene layer providing unmatched chemical resistance and low friction surface for media contact.
- Limit Rod: Safety feature preventing joint separation under excessive tension.
- Flange: Connection component available in carbon steel or stainless steel for secure installation.
