Vented Straight Brass 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. 


This brass gage is installed vertically.  It 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.


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