ABSTRACT:
A pressure indicating fitting for injection molding equipment comprises a fitting body with a fitting bore therethrough, the fitting body being installed in the equipment with the fitting bore open to the interior of a passage for conveying melt, an indicating member received within the fitting bore and being bonded thereto to be retained in a normal position and being displaced therefrom to an indicating position by force from melt applied to the indicating member sufficient to cause the bond to fail, the indicating position determined by abutting contact of a surface of the indicating member with a surface of the fitting body and exposing a portion of a stem of the indicating member. Advantageously, the indicating member is retained in an indicating position by a press fit between the indicating member and fitting body. An injection molding manifold comprises a pressure indicating fitting in accordance with the invention.
