A system and apparatus for pressurizing pipe includes a resilient and compressible plug insertable into the opposed ends of the pipe for sealing the pipe. The plug includes a plug body having a larger outside diameter than the inside diameter of the pipe, a flange that limits insertion of the plug into the pipe, and a blind hole coaxial with the plug for receiving the rod of a pushing member used to force and push the plug into the pipe. The rod has a smaller diameter than the hole for allowing the plug to compress during insertion for fitting into the pipe. After insertion of the plugs pipe pressurization occurs by securement of the needle end of an air pressure gun to a cylindrical needle shield that is circumjacently placed on the pipe for needle end alignment whereupon the needle end perforates the plug for pipe pressurization, and as the needle end is withdrawn the plug body compresses and closes the temporary needle slot thereby sealing the pipe.
