EWK 500cc Fluid Extractor Syringe — Manual Oil Suction Pump with Hose, Double O‑Ring, Non‑Drip Cap

EWK's 500cc fluid extractor syringe is a handheld manual pump that draws and dispenses automotive fluids precisely into tight reservoirs and hard-to-reach ports.

Compact and purpose-built for vehicle maintenance, this 500cc syringe combines a secure hose connection, double O-ring piston, and a non-drip cap to make extracting or refilling fluids neater and faster. Constructed from chemical-resistant polyethylene, it works for common automotive liquids while keeping operation simple — no batteries or power tools required. The tool is ideal for small-volume jobs like topping off power steering, bleeding brakes, servicing transmissions or differentials, or transferring fluids in confined engine-bay spaces.

How does this syringe help when access is limited?

The narrow hose and hand-operated piston let you reach into cramped service points where funnels and jugs won’t fit. You can draw or introduce fluid without tilting containers, reducing spills and contamination risks. The compact shape also makes it easier to position the tip precisely at the filler or drain opening.

• 500cc chamber for controlled small-volume transfers
• Flexible hose fits tight filler necks and bleeder valves
• Handheld size for accurate placement in engine bays
• Non-drip cap prevents mess during interim handling

What features prevent leakage and backflow?

This extractor uses a double O-ring on the piston to maintain a consistent vacuum during suction and dispense cycles, minimizing the need to re-prime. A threaded locking nut secures the tubing to the syringe so the hose won’t pop off under pressure. Together these components cut down on leaks and give steadier fluid movement.

• Double O-ring piston for stable suction and reduced backflow
• Locking nut keeps hose clamped during operation
• Clear chamber for visual fluid level monitoring
• Non-drip cap to contain residual fluid when paused

Which fluids and temperatures are safe to use?

The syringe is made from robust polyethylene chosen for resistance to common vehicle fluids such as gear oil, power steering fluid, brake fluid (where appropriate), and transmission fluids. It is designed for typical maintenance temperatures — avoid using fluids hotter than 110°F (45°C) to preserve seals and plastic parts.

• Compatible with common automotive fluids under normal service temperatures
• Not intended for hot liquid transfer above 110°F (45°C)
• Durable material resists routine chemical exposure
• Avoid long-term storage of fluid inside the chamber

How does the non-drip cap and locking nut improve workflow?

The non-drip cap lets you cover the hose tip while you move the syringe to a waste or refill container, reducing stray drops and stains. The locking nut secures the hose so you can operate the pump one-handed without the risk of the tube disconnecting mid-transfer. Together these small design choices speed up repetitive tasks with fewer interruptions.

• Cap reduces secondary dripping during repositioning
• Locking nut enables one-handed operation and steady suction
• Streamlined transfer reduces cleanup time and waste
• Clear markings and chamber visibility speed job checks

Who is this for? DIY mechanics, professional technicians, and vehicle owners who perform routine fluid maintenance will find this EWK 500cc fluid extractor valuable when working in confined engine areas or handling small-volume fluid changes. It’s particularly useful for topping off power steering or transmission fluid, sampling or removing residual fluid for inspection, and quick bleed or refill jobs where accuracy and a tidy workspace matter.
