316 Stainless Steel Liquid Level Gages with Dial Thermometers are for any application requiring visual indication of both liquid level and liquid temperature. These gages can be used to view liquid levels and temperatures in hydraulic reservoirs, gearboxes, bearing housings, crankcases, transformers and machinery oil reservoirs. The temperature can be easily viewed on the large thermometer.","This sturdy gage is constructed with 316 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. Temperature is indicated in both degrees Fahrenheit and Celsius on the 2 3\/64 diameter 304 stainless steel thermometer. It displays 0 ° F (-20° C) to 250° F (120° C). 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.","To view NPT adapters for 316 stainless steel gages, click here .
