Abstract

Abstract An improved throttle modulator assembly and a thermoplastic fluid direction tube for insertion into a throttle modulator assembly are disclosed. The thermoplastic fluid direction tube is annular and hollow and is made from a thermoplastic material having a coefficient of thermal expansion about the same as the throttle modulator body. Further, an annular press ring and at least one associated press wing extending axially therefrom are located along the longitudinal dimension of the end tube portion of the thermoplastic tube.
