Selecting the right option
Match the O-ring to the union size, and check that your union is a BSM (RJT) type with the standard liner and male: Dixon's CIP flat-face unions and its NZ RJT unions use different O-rings and gaskets (manufacturer-stated). Choose Buna-N only if it suits your product and cleaning chemicals. Dixon also lists FKM RJT O-rings (the 40MP-SFY...RJT series); ask us if you need them. Dixon's compound guide rates Buna as satisfactory (A) for vegetable oils, mineral oil and kerosene, and as unsatisfactory (D) for acetone and ozone (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).
