Mission Flex-Seal® Pipe Coupling, Flexible, Series: MR56, Fitting/Connector Type: Coupling, 3 in Nominal, Cast Iron/Plastic x Cast Iron/Plastic, 4 in Length, Method of Manufacture: Molded, Synthetic Rubber, Natural, Domestic/Import: Domestic

 Flexibility - sleeve is manufactured of molded natural and synthetic rubber

Leak-proof seal - inside surfaces of transitional size couplings are stepped to conform better to different pipe sizes

Tight fitting - two 300 series stainless steel worm drive clamping bands hold pipe ends securely

Corrosion resistant - use of stainless steel clamping bands are highly effective in a variety of environments

Versatile - blends of natural and synthetic rubbers permit a substantial degree of distortion without change in basic physical or chemical resistance unlike other manufacturers' thermoplastic coupling materials

An extensive line of flexible sewer coupling that connect similar and dissimilar pipe materials and sizes

Manufactured with natural and synthetic rubbers conforming to ASTM C425, ASTM C1173

Flex - seal couplings have a tolerance range of approximately +/- 3% on sizes up to 12 in nominal Dia
