Style 89 is constructed with heavy ductile iron housings, designed for use on stainless steel pipe only. The housing key is wider than standard and the coupling housing is designed to clamp the bottom of the groove, thus providing an essentially rigid joint. To achieve this rigidity, it is necessary to torque the nuts to the values shown in the table below. For pressure ratings, see page 2 for pressure ratings based on ANSI wall thicknesses and page 3 for those based on ISO wall thicknesses.

Style 89 will greatly reduce linear or angular movement and is useful for valve connections and other points where rigidity is required. The coupling is provided with plated bolts and nuts and pressure responsive gaskets for a variety of services (please specify gasket grade when ordering. Request publication 05.01 for gasket service ratings).

Style 89 couplings are suitable for use on stainless steel piping where the corrosion resistant properties of stainless are not required for the external environment.
