EWK 500cc Fluid Extractor Syringe — Manual Oil Suction Pump, Chemical-Resistant Polyethylene with Double O-Ring and Non-Drip Cap

EWK's 500cc fluid extractor syringe is a manual oil suction pump designed to draw and transfer transmission, differential, power steering, and brake fluids cleanly from tight access points.

This compact, hand-operated syringe offers a controlled way to extract and refill automotive fluids when pouring is impractical or messy. Built from chemical-resistant polyethylene and fitted with a double O-ring piston and locking nut for the hose, the tool focuses on steady suction, secure connections, and minimal drips during routine maintenance. It's sized for small reservoirs and service jobs where a quick, accurate fluid change or top-up is needed.

How does the EWK syringe make fluid changes neater?

The syringe lets you draw fluid directly from tight ports without lifting and pouring from heavy containers, which reduces spills and contamination. A non-drip cap and a secure hose attachment prevent unexpected leaks while you move fluid to a waste container or refill a reservoir.

• 500cc chamber to limit repeated filling
• Non-drip cap to reduce transfer drips
• Locking nut keeps hose firmly attached during one-handed use

What features ensure reliable suction and less backflow?

EWK equipped the pump with a double O-ring piston that improves vacuum stability compared with single-ring designs. That steadier vacuum means fewer re-primes, less air intake, and reduced backflow when extracting or injecting fluid.

• Double O-ring piston for consistent draw-and-transfer cycles
• Clear chamber to monitor fluid level and flow
• Manual control allows precise volume adjustments while working

Is this tool durable and which fluids can it handle?

The body and fittings are made from solid polyethylene chosen to resist normal automotive chemicals and routine heat exposure. It’s intended for common fluids like transmission oil, gear lube, power steering fluid, and brake fluid, but avoid using hot liquids above 110°F (45°C).

• Chemical-resistant polyethylene construction for routine maintenance
• Safe for most automotive fluids under recommended temperatures
• Avoid solvents or temperatures above 110°F (45°C)

How do I use it safely and keep the tool performing well?

Use the syringe to draw fluid slowly, then cap the hose with the non-drip cover when transporting to a waste container. Clean the hose and chamber after every use, store dry, and never leave fluid inside the chamber between jobs.

• Draw and transfer slowly to prevent splashing and air locks
• Wipe and rinse the hose and chamber after each use
• Do not store fluid inside the syringe; use the cap only for temporary holding

Who is this for: The EWK 500cc fluid extractor syringe is ideal for DIYers, home mechanics, fleet technicians, and anyone who performs routine vehicle maintenance on tight or awkward access points. It suits small fluid changes, top-ups, and diagnostic draws where control, cleanliness, and a compact size matter. If you need a simple, reusable hand pump to reduce spills and speed small-service tasks, this tool is built for that purpose.
