FOUR UNCLES 500cc Fluid Transfer Syringe with Hose for Oil

This aluminum-handled 500cc syringe pairs a large-volume chamber with a flexible extension hose to speed up routine service tasks such as transmission fluid changes, differential servicing, and topping up hard-to-reach reservoirs. Built for repeatable garage use, the tool focuses on controlled flow and reach so you can work cleaner and faster than with smaller plastic syringes.

How does this syringe make fluid changes quicker?

The 500cc volume reduces the number of pump cycles needed to move fluids, meaning larger transfers can be completed with fewer interruptions. The one-handed piston action and solid aluminum handle deliver steady pressure so each stroke moves a predictable amount of liquid.

• 500cc chamber lowers cycle count for bulk transfers
• Aluminum handle gives firmer, repeatable strokes
• Consistent piston action helps avoid spills and overflows

Can it reach confined or deep service points?

Yes — the included flexible hose extends reach into narrow openings and recessed ports commonly found on transmissions, transfer cases and differentials. The hose bends around obstacles while maintaining flow, so you don't need to dismantle surrounding components just to access the fill or drain point.

• Flexible extension hose navigates tight spaces
• Long enough for many recessed service ports
• Works without removing surrounding panels or brackets

Is the construction suitable for repeated garage use?

This syringe is built with a durable aluminum handle rather than typical plastic, improving longevity and hand comfort during frequent use. Seals and piston geometry are tuned for automotive fluids, so the tool withstands oil and gear lubricants typically used in maintenance settings.

• Aluminum handle resists wear from repeated pumping
• Robust seals designed for common automotive fluids
• Solid construction reduces chance of cracking or failure

What kinds of fluids and tasks is it best suited for?

The syringe works well for transmission fluid, gear oil, differential fluid, power steering fluid, and other compatible automotive liquids. It’s intended for extraction, topping up, and controlled dispensing rather than pressurized injection tasks.

• Recommended for transmission and differential services
• Ideal for topping off reservoirs in confined areas
• Not intended for high-pressure hydraulic systems

Who is this for: the FOUR UNCLES 500cc Fluid Transfer Syringe is aimed at professional mechanics, serious DIYers, and garage owners who perform regular fluid maintenance and need a reliable, higher-capacity hand pump. If you service transmissions, differentials, or other tight-fill components and want fewer pump cycles, better grip, and extended reach, this syringe provides a practical, workshop-ready solution without expensive equipment.
