304 Stainless Steel Liquid Level Gages can be used to view liquid levels in hydraulic reservoirs, tanks, large steel mill pumps, gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs.  Their use can be extended to any industrial liquid level viewing application. 

This sturdy gage is constructed with 304 stainless steel.  The glass sight is protected by stainless steel on three sides.  A red line on a white background enhances liquid level visibility.  Leak-proof construction is achieved with Buna-N seals.  The unit tolerates up to 125 PSI and 225° F. 

Fluid enters through the cross hole in the hollow lower bolt.  The gage is vented into the tank through the cross hole in the top bolt.   The length between the center of the two bolts is referred to as the centerline.  The distance between the center of the tank holes must be within 1/32” of the centerline measurement.  This gage is mounted from the front of the tank with (2) 1/2”-20 stainless steel bolts.  The bolts should be torqued to 90 in-lbs.
