Detailed Product Description

Single Sphere EPDM NBR CR Expand Joint Rubber Flanges

Product Description

Rubber Flanges are flexible pipe connectors manufactured with EPDM, NBR or CR elastomer, reinforced by multi-layer nylon cord and steel wire rings. Equipped with carbon steel/stainless steel floating flanges, they are widely installed between pumps, chillers and piping systems to absorb axial, lateral & angular displacement, isolate vibration, reduce pipeline noise and compensate thermal expansion.

EPDM version: For hot/cold water, seawater, acid & alkali solution, outdoor HVAC systems
NBR version: Excellent resistance to mineral oil, diesel, hydraulic fluid and edible grease
CR neoprene version: General-purpose for compressed air & mixed light oil-water medium

Performance characteristics

1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced Expand Joint provides long-lasting performance.
3. Corrosion Resistance: Resists aggressive environments and chemicals.
4. Noise & Vibration Reduction: Dampens vibrations and shock waves.
5. Ease of Installation & Maintenance: Compact design and standard flange connections facilitate installation and upkeep.
