Functional engineering application
The 3 Inch × 2 Inch Concentric Reducing Rubber Expansion Joint (DN80 × DN50) is an engineered dual-purpose flexible connector designed to join a 3" (DN80) suction supply pipe directly to a 2" (DN50) pump suction flange. By combining pipe size reduction and vibration dampening into a single EPDM rubber body, it eliminates extra pipe fittings, saves installation space, and isolates high-frequency pump noise up to 16 Bar pressure.
Concentric 3" × 2" (DN80 × DN50) PN16 reducing EPDM rubber expansion joint for direct pump suction reduction & vibration isolation.
