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. This gage is specially configured with a 1/4” male NPT connection cap that can be used to vent the gage back into the reservoir. The gage uses only atmospheric pressure. Buna-N seals are used. The unit tolerates temperatures up to 225° F.
