摘要
A connection apparatus for mounting a water gauge in a water gauge protecting box is provided to prevent the water from being leaked through a screw groove without forming the screw groove in a connection part by making an insertion part of a connection pipe inserted into an O-ring and slid inside/outside. A connection apparatus for mounting a water gauge(4) in a water gauge protecting box comprises the first O-ring, an annular flange and a coupling nut. Inside an outlet(5a) of an angle valve(5) which is mounted at a upper part of a water supply pipe(2), the first O-ring is installed. The annular flange is installed at the other end of the outlet. The coupling nut is screw-assembled in a water inlet of the water gauge.
