Standard Aluminum Liquid Level Gages can be used to view liquid levels in hydraulic reservoirs, 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 made of corrosion and rust resistant milled aluminum. The end pieces are permanently secured through a staking process. The unit tolerates up to 175 PSI and 225° F. The liquid viewing sight is glass. Leak-proof construction is achieved with Buna-N seals.
Fluid enters through the cross hole in the hollow lower bolt. The gage is vented into the tank through the cross hole in the hollow 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 to the tank with (2) 1/2”-20 aluminum bolts. The back mount design requires that the inside of the tank be accessible in order to secure the bolts with plated steel hex nuts. The mounting bolts should be torqued to 90 in-lbs.
For additional mounting options, seals and fractional inch centerline distances, reference the “Other Options” document located on this page.
