ABSTRACT:
An adapter pad is provided for use with an inventive split flange to couple a standard S.A.E. pressure flange coupling to a pressure port requiring a step size flange. The adapter pad has a central flow port therein of a diameter corresponding to the flange coupling inner diameter and has an upper face adapted to interface with the terminal face of the flange coupling head and a lower face has an annular gasket groove therein for connection to a hydraulic component. The upper face of the adapter pad may also be provided with a central circular upraised portion having an inner threaded bore for mating with a standard size fitting, which may have any of the standard angular bends. The inventive split flange is provided with a double circular recess, which forms two shoulders for securing either the standard flange coupling or the flange coupling in combination with the adapter pad.
