Single Sphere EPDM NBR CR Expand Joint Flange Type Expansion Joint Plumbing
Product Description
Single sphere flange type expansion joints are essential flexible connectors for plumbing and industrial piping systems. Manufactured with premium EPDM, NBR and CR rubber materials and reinforced multi-layer cord fabric with built-in steel wire rings, these plumbing expansion joints feature excellent pressure resistance, flexibility and structural stability. Equipped with standard flanged ends, they enable fast installation, reliable sealing and perfect pipe alignment for various plumbing projects.
Different rubber formulas meet diverse medium requirements: EPDM for hot and cold water, seawater and weak acid-base fluid; NBR for mineral oil, diesel and hydraulic oil; CR for compressed air and general plumbing media. The single-sphere flexible structure effectively absorbs thermal expansion displacement, compensates installation errors, isolates pump vibration, reduces pipeline operating noise and buffers water hammer impact. Widely used in HVAC systems, domestic water plumbing, municipal water supply and industrial piping facilities, customized sizes and pressure grades are available.
