ABSTRACT:
A cap of resilient material such as rubber or the like has a generally cup-shaped form for covering at least the head portion of a bleed screw which is mounted on a body of a hydraulic component such as a hydraulic actuator or the like to normally close an air bleed passage formed in the component. The cap comprises a generally cylindrical skirt portion depending integrally from the cup-shaped portion to abut with the surface of the body of the hydraulic component, and a projection formed on the inner circumference of the cap for engaging with a small diameter portion formed on the bleed screw, whereby the lower end of the skirt portion is urged resiliently against the body of the hydraulic component.
