TEC Products FlexAll long flexible oil change funnel — 16in red nitrile, chemical‑resistant & high‑temperature

TEC Products FlexAll is a 16-inch, nitrile rubber oil change funnel designed to flex, resist chemicals and temperatures, and make fluid transfers cleaner and easier for automotive work.

This long, red flexible funnel from TEC Products is built for hands-on vehicle maintenance where access is tight and spillage is costly. Made from seamless nitrile rubber, it bends to fit awkward fill points, resists oil and fuel, and tolerates a wide temperature range so you can use it in chilled garages or warm engine bays. The 5-inch mouth and tapered body combine capacity and control, letting you pour transmission fluid, engine oil, coolant, or kerosene with less mess than rigid plastic funnels.

How does the nitrile rubber construction improve durability and safety?

The funnel’s nitrile rubber body resists oils, fuels, and many solvents better than standard plastics, reducing swelling and degradation over time. Its seamless build lowers leak risk and the flexible material helps prevent cracking when manipulated into tight spaces. That reliability makes it suitable for repeated professional or DIY use without frequent replacement.

• Seamless nitrile rubber resists chemical attack and maintains flexibility
• Durable under repeated bending and handling
• Less prone to cracking or splitting than some plastics

What fluids and temperatures can this funnel handle?

The FlexAll funnel is engineered to manage a variety of automotive liquids, including transmission fluid, engine oil, antifreeze/coolant, and kerosene. Its operational temperature range from -21°F to +221°F means it performs reliably in cold storage or hot working conditions without losing form or function.

• Compatible with oils, fuels, coolant, and light solvents
• Stable between -21°F and +221°F for garage or shop use
• Smooth interior reduces residue buildup across different viscosities

Will the size and shape work for tight fill points and high-volume pours?

The 16-inch length and 5-inch mouth provide reach and flow capacity for elevated or recessed fill openings, while the flexible body lets you bend the funnel to line up with awkward angles. The wide mouth accelerates filling, and the smooth inner surface keeps fluid moving without trapping drips that cause messes.

• 16" length reaches deep or recessed filler necks
• 5" diameter mouth supports faster pours and higher volumes
• Flexible shape adapts to hard-to-access fill locations

How do you clean and store the funnel for long service life?

Cleaning is straightforward: flush with a suitable solvent or soap and water after each use, then hang or lay flat to dry. Store the funnel away from direct sunlight and sharp objects to avoid surface damage, and inspect before use for cuts or excessive wear.

• Flush with detergent or solvent depending on fluid used
• Dry fully before storing to prevent trapped residue
• Keep out of UV exposure and away from sharp edges

Who this product is for: TEC Products FlexAll Long Flexible Funnel suits automotive technicians, fleet maintenance teams, and home mechanics who need a tough, adaptable funnel for varied fluids and tight access points. It’s especially useful when spills must be minimized and tools must withstand regular shop conditions. Made in the USA by a family-owned Michigan company, it’s a practical upgrade from brittle plastic funnels for anyone who performs routine fluid changes or occasional vehicle maintenance.
