Crude oil sample catchers and oil thieves

• Model A Is Equipped with an Aluminum Barrel
• Model B Features a Brass Barrel
• Model C Features a Clear Barrel and Has Tie-Rod Construction

We offer Tulsa Oil Thieves in three models and five sizes. All of the sample catchers feature single trip (original with the Tulsa Thief), antifouling flat-ball assembly, a full opening horizontal closure system with rotating valve, two adjustable springs (one for closing tension and one for tripping tension for more flexible adjustment) and adjustable graduated trip rods that hold the thief in an upright position as a hydrometer cylinder. Other than near the top or base castings, petcocks can be installed at any point on any style oil thief. Additionally, the plastic barrels will not crack if the petcock strikes an object.
