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 many industrial liquid level viewing applications. This gage is specially configured.","This patented gage is constructed with sleek, corrosion resistant black anodized aluminum. The end pieces are permanently secured through a staking process. An aluminum ball float inside the glass sight enhances liquid level visibility. White laser engraved Full\/Hot, Full\/Cold and Low level markings are easy to read against the black body of the gage. The unit tolerates up to 175 PSI and 300° F. Leak-proof construction is achieved with Viton seals.","Fluid enters through the cross hole in the hollow lower bolt. The gage is vented into the tank through 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 7 centerline measurement. This gage is mounted from the front of the tank with (2) aluminum bolts with 1\/4\" Male NPT Adapters.
