Abstract
A pressure cylinder, such as a master cylinder, primarily for use in a vehicle brake or clutch hydraulic system includes a cylinder component molded from plastics material, and an initially separate flange component which is preferably but not essentially, also molded from plastics material. The two components are provided with an interconnecting arrangement capable of transmitting axial thrust between the two components, and also resisting relative rotation therebetween.
