Constant Level Oiler 9 Oz Pyrex Viton With Vented Pipe Plug

Item # YB4159-13, Constant level Lubricator With Oil Level Sight, 9 oz Pyrex Reservoir, with Vent Plug Constant Level Lubricators With Oil Level Sights automatically maintain a fixed liquid level in a bearing housing or gear box using the liquid seal principle. This constant level lubricator features a large sight for viewing the liquid level and condition. Constant level lubricators can be used on sleeve bearings, anti-friction bearings, gear boxes, pump housings, ventilating fans and blowers, moistening pads, and any other application demanding the maintenance of a constant liquid level. This Constant Level Lubricator withstands temperatures up to 225°. It features a 9 oz Pyrex reservoir, aluminum alloy body, and Viton seals. The glass sight viewing area is 1 9/16” dia. The unit is pipe mounted. There are (2) 1/2” female NPT outlets. One is located on the side of the unit, and the other is located on the bottom of the unit. A pipe plug is installed in the bottom outlet, and vented pipe plug is installed in the 1/8” NPT air vent. The diameter of the reservoir is 3,” the viewable height of the reservoir is 2 3/4”, and the total height of the unit is 8 11/32”. Liquid Seal Principle When liquid consumption causes the liquid in the bearing to recede, the liquid seal on the inside of lubricator is temporarily broken, allowing air from the air vent to enter the lubricator’s reservoir. This causes oil to be released from the lubricator into the bearing until the proper liquid level is reached, at which time the liquid seal in the lubricator is reestablished. Oil-Rite Constant Level Lubricators feature a unique, mess-free design that allows the reservoir to be easily refilled through a top filler cap. A shutoff valve holds the liquid in the reservoir when the filler cap is removed. The lubricator resumes normal functioning after the cap is screwed down again. It is important that the filler cap is screwed down tightly to ensure proper operation. Installation For proper installation, a liquid level line is scribed on the base of the unit. Mount the lubricator using the side or bottom outlet at the exact and most desirable level. The correct level is the lowest level at which the bearing operates perfectly. The lubricator should be level in all directions. Keep all connections short, rigid and close to the bearing to avoid vibration. Fill the bearing well by filling the lubricator, refill when necessary.
