Long plug with large flange especially suitable for sealing the female part of quick connectors in fuel lines. The length of the plug ensures tight internal closure not only while transportation but during pressure tests as well. The flange protects the external surface, and makes the plug easy to remove. Available with a horizontal handle for added flexibility in packaging and ergonomics. Some plugs meet the requirements of the SAE J2044 standard; therefore, the dimensions given for the diameter are not that of the plug itself but of the nominal size of the pipe for which it is suitable.
