Thorstone 500cc Fluid Extractor Pump with 2 PVC Suction Tubes — Clear Barrel, Leak-Resistant Seal

Thorstone's 500cc fluid extractor pump is a hand-operated vacuum syringe that safely draws and dispenses automotive fluids using two PVC suction tubes and a leak-resistant adapter.

Whether you need to remove transmission fluid from a hard-to-reach drain or top up brake and power-steering reservoirs without spills, this compact syringe-style pump gives controlled suction and injection. The clear 500cc barrel and included tube set let you see liquid flow, while the locking mechanism and dual rubber seals reduce drips and air leaks for cleaner servicing.

How does the Thorstone pump make fluid changes easier?

The syringe format delivers precise, manual control so you extract or add small volumes without pumps or lifts. Its transparent body shows fluid levels as you work, and the two tube diameters handle different viscosities and port sizes.

• Hand-actuated vacuum for incremental removal and filling
• Clear 500cc barrel for visual monitoring
• Two tube sizes (0.24" OD and 0.32" OD) for varied fittings
• Locking button to secure the tube during use

Can I use this on different vehicle systems and liquids?

Yes, the extractor is designed to resist oils and common automotive chemicals, enabling use on gearboxes, brake reservoirs, coolant systems and more. It’s suitable for small engines and larger vehicles when used for accessible service points.

• Compatible with transmission, brake, power-steering and antifreeze fluids
• Works on cars, trucks, ATVs, boats, lawn mowers and RVs
• Chemical- and oil-resistant materials for durability
• Non-drip silicon connector included for tidy transfers

What features prevent leaks and contamination?

The Thorstone pump uses a dual-rubber ring inside the plunger to create an airtight seal and precision threading at the tube connection to stop seepage. The locking adapter secures the tube so you can hold the syringe steady while extracting or dispensing.

• Dual rubber ring seal for airtight suction
• Precision-threaded tube end to reduce leakage
• Locking button to keep tube attached and stable
• End caps for tubes to prevent spills when stored

How do I maintain and store the fluid extractor?

Rinse and dry the barrel and tubes after use to prevent contamination and extend service life. Store the syringe with tube caps on and keep the non-drip connector in place to avoid residue buildup.

• Flush with compatible solvent or warm soapy water after use
• Dry thoroughly before reassembly and storage
• Keep tube end caps and silicon connector attached when not in use
• Inspect rubber seals periodically for wear and replace if needed

Who this is for: DIY mechanics, fleet technicians and hobbyists who perform routine fluid maintenance will appreciate Thorstone’s 500cc extractor for tasks that require control and cleanliness. It’s aimed at anyone servicing cars, motorcycles, small engines, boats or garden equipment who needs a portable, leak-resistant tool for extracting and adding liquids without specialised shop equipment.
