Abstract
Abstract The present invention relates to a temporary plug for hydraulic and fluid ducts, which comprises a head (1) rigid, at the bottom thereof, with a hollow body (2), having a thread on its outer surface and longitudinal notches (3) or cut-outs, which allow for the hollow body (2) to be snap engaged with threaded seats formed at operating interruptions of hydraulic ducts or pipes included in a hydraulic, fluid or pneumatic circuit. The engaged plug may be either safely threaded in order to shut off the fluid in the ducts, or it may be successively withdrawn to complete the assembling of the duct or hydraulic circuit.
