Vented Union Coupling Elbow Steel 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 plated steel elbow gage features a 1/2” diameter glass sight that retains its clarity through various temperature changes.  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.  Leak-tight construction is achieved with Buna-N seals. The unit tolerates temperatures up to 225° F.
