ABSTRACT:
A housing member (100, 100', 100", 100'") used to interface with a coupling of a fluid pressure source and to house a pressure sensing assembly is shown having a metallic tubular sidewall with a cylindrical first portion (102), a non-cylindrical second portion (108, 108') and intermediate third portion (112, 112',112") with a plastic body member (114, 114', 114") disposed, as by insert molding, within the tubular sidewall. The plastic body member has a base wall portion (116) extending across the sidewall at the intermediate, third portion (112) and has an elongated portion (120, 120') with a threaded bore. The second portion of the sidewall extends along a longitudinal axis at least as far as the elongated portion of the plastic body member. In one embodiment a metallic insert (152) forms a continuation of the molded plastic thread and in another embodiment inwardly extending groove (160) of second portion (108') of the tubular sidewall reinforces the molded plastic thread. The housing member is adapted to receive a pressure sensing mechanism within the first portion (102) which portion is attached to a connector or the like by clamping the outer distal end (106) thereto.
