Vented Union Coupling Brass Elbow Gages can be used on oil bearings, gear boxes, crank cases, transformers, switches or any application requiring visual indication of liquid level.  The leak proof construction, large vent hole and unrestricted passages permit fast and accurate liquid level response. 

 

The square shank with pipe thread screws horizontally into a tapped hole. A full rotational clearance is not necessary; the union coupling is installed without rotating the entire gage. 

 

This brass elbow gage features a 1/2” diameter glass sight protected by a shield.  The shield can be revolved to the most convenient position for viewing or taken off completely for cleaning.  A protected vent hole in the cap reduces the possibility of dust, dirt, or moisture getting inside the gage.  The gage uses only atmospheric pressure.  A Teflon washer reduces friction between the cap and the glass during installation and adjustments.  Buna-N seals are used. The unit tolerates temperatures up to 225° F.

 

Union Coupling Brass Elbow Gages can also be custom built with alternate caps.  To view the optional caps, click here.
