The FV-RJ-S1 single sphere rubber expansion joint is our best-selling series. The moulded EPDM sphere absorbs axial, lateral and angular movement, attenuates pump vibration and compensates for pipe misalignment. Arch design to EN ISO 9631, flange drilling to DIN PN10/16, ANSI 150# and JIS 10K from stock tooling.

Full-face rubber flanges with steel backing rings on request. Every joint is hydrostatically tested at 1.5× working pressure before packing.
