Key specifications

Nominal sizes in mm are those Dixon prints against each inch size in its hygienic fittings catalogue.

Selecting the right option

Match the gasket to the ferrule size of the clamp joint, and to the material that suits your product and cleaning chemicals. Temperature ratings for clamp gasket materials vary between Dixon publications, so no range is given here; ask us to confirm the rating for your duty before you specify hot service. The 1/2 in and 3/4 in gaskets use the 42MP series and the 1 in and larger gaskets use the 40MP series, so do not mix the two when ordering. Dixon's compound guide rates FKM as satisfactory (A) for gasoline, mineral oil and vegetable oils, and as unsatisfactory (D) for acetone and methyl alcohol (manufacturer-stated). Those ratings assume static conditions at ambient temperature, and Dixon describes the guide as general only, with suitability for a specific application resting with the end user (manufacturer-stated).
