    Operation<\/h2>\n

     <\/p>\n

    GK couplings are connected by pressing and turning the two connections together. The distance between the teeth is 40 mm and therefore all sizes from DN 10 to DN 38 are interchangeable. GK couplings are not interchangeable with Express couplings complying with NF E 29.573 and European air couplings complying with DIN 3489<\/p>\n

    N.B.: Due to the wide range of GK type seals, GK couplings cannot always be connected to those of other manufacturers.<\/p>\n
