Item #: 96044

AMOUNT OF OIL:   There is no set amount of oil that has to be put into the U-gauge. But it needs to be enough so that if a neon unit is filled to 20mm pressure, the oil in the U-gauge does not go past the bottom of the U-tube, which would cause the fill gas (or air) to bubble up the right side of the gauge. If this happens it does not cause any permanent damage, but will delay accurate readings until the oil drains down the tube and settles again.
