Samplers and Oil Thieves

70000 Series – Full Opening Design

The Tulsa Oil Thief is manufactured in three distinct models across five different sizes to meet various operational requirements.

Model Configurations

Model A features an aluminum barrel with durable riveted construction, while Model B utilizes a brass barrel also built with riveted assembly. Model C stands apart with its clear barrel design and employs tie rod construction for secure barrel retention.

Universal Features

Every Tulsa Oil Thief incorporates these standard features:

• Single trip operation – the original innovation pioneered by the Tulsa Thief
• Antifouling flat bail assembly for reliable performance
• Full opening horizontal closure system featuring a rotating valve mechanism
• Dual adjustable spring system – separate springs control closing tension and tripping tension for enhanced operational flexibility
• Side hanger integrated into the top casting for convenient mounting on hatches or equipment cases
• Adjustable graduated trip rod that serves dual purposes as both a positioning aid and fourth support leg, allowing the thief to function as a hydrometer cylinder when positioned upright

Customization Options

Petcock installation is available at any location along the barrel except near the top and base castings, providing flexibility for specific sampling requirements.

Enhanced Durability

The plastic barrels used in Model C are constructed from impact-resistant materials specifically chosen to prevent cracking even when the petcock contacts solid objects during operation.

72000 Series Tulsa Oil Thief

The 72000 series Tulsa Oil Thief is engineered for specialized narrow opening applications, accommodating openings with a 5-inch minimum clearance.

Key Design Features

Proven Assembly Components:

• Time-tested simple bail assembly for reliable operation
• Convenient hook integrated into the top casting for easy handling
• All-brass castings providing non-sparking safety in hazardous environments

Advanced Spring System:

• Adjustable trip spring for customized activation sensitivity
• Adjustable valve closer spring enabling precise closure control

Sealing Technology:

• Simple O-ring seal on the valve plate for leak-proof performance
• Maintenance-free valve pivot shaft requiring no additional sealing

Operational Capabilities

Sampling Flexibility:

• Multi-level sampling capability – collect samples from bottom or any desired depth
• Adjustable graduated trip rod for precise depth measurement
• Four-leg bottom casting ensures stable, even support during operation

Compact Design Advantage:

• Internal pivot valve design maintains slim profile without external protrusions
• Streamlined construction specifically designed for restricted access applications

Durability and Maintenance

The 72000 series is built for field repairability and rugged performance in demanding environments. Petcocks can be installed at any barrel location except near the top or base castings for enhanced sampling versatility.

Model Comparison

Unlike the 70000 series which features a full opening horizontal closure system with rotating valve, the 72000 series prioritizes compact design for narrow access points while maintaining sampling accuracy.
