DN150 Full Face Sealed EPDM Rubber Expansion Joint with Carbon Steel Flanges PN16
A Full Face Sealed Rubber Expansion Joint is a flexible pipe connector designed to absorb movement, reduce vibration, and compensate for misalignment in piping systems.
Unlike standard rubber joints, this type features a full-face sealing flange, meaning the rubber sealing surface extends over the entire contact face of the flange. This provides enhanced sealing performance, especially in high-pressure, vacuum, or corrosive environments.
Key Features:
Full Face Sealing Design: The rubber flange covers the entire metal flange face, ensuring tight, leak-proof sealing across the entire surface.
High Flexibility: Capable of absorbing axial, lateral, and angular displacements in pipelines.
Corrosion and Wear Resistance: Available in EPDM, NBR, Neoprene, or other rubber materials suitable for different media and temperatures.
Vibration and Noise Reduction: Effectively isolates vibration and dampens noise transmission in mechanical systems.
Vacuum-Resistant (Optional): Some models can be designed for partial or full vacuum conditions.

Advantages over Standard Rubber Joints:
1. Better sealing against flange faces (especially on uneven or corroded flanges)
2. Reduced risk of media leakage in high-pressure or critical applications
3. Enhanced durability and reliability
