Oil Thief Samplers

Butterfly Valve Type – Compact Design

The Robinson Oil Thief is a proven design in oil thieves. The valve closure assembly is on the inside of the barrel, which makes a more compact unit at the bottom, allowing the thief to pass through an opening as small as 5 inches in diameter. The bottom casting has four legs which makes the thief a stable hydrometer cylinder. The top casting has a hanger for hanging the thief. It offers a single trip action, simple tension adjustment, simple seal and o’ring adjustment, adjustable graduated trip rod and viton seals.

*Special design drain valves may be installed at any position on the thief barrel, except near top or base castings
