TEC Products Flexible Oil Funnel 12-inch Nitrile — 4-inch Mouth, Long Reach, Chemical-Resistant

TEC Products FlexAll is a 12-inch, single-piece nitrile rubber oil funnel built to flex, resist chemicals, and make spill-free fluid transfers during automotive service.

When changing oil or topping fluids, a reliable funnel reduces mess, speeds the job, and protects seals and components from contamination. The FlexAll funnel from TEC Products is molded from nitrile rubber (NBR) to hold its shape while bending into tight service positions, with a 4-inch mouth for fast pour rates and a 12-inch length for reach into deep fill points. It’s designed for mechanics, home DIYers, fleet technicians, and anyone who wants a durable, reusable funnel that resists common automotive fluids and temperature extremes.

How does this funnel handle different automotive liquids?

The FlexAll funnel is formulated to be compatible with a broad range of fluids used in vehicle maintenance without swelling or degrading. Because it’s high-quality nitrile rubber, it tolerates oils, fuels, and antifreeze while keeping its shape and sealing capability.

• Compatible with engine oil, diesel, gasoline, ATF, gear oil, hydraulic fluid, and ethylene glycol-based antifreeze.
• Chemical resistance reduces softening or cracking from repeated exposure.
• Temperature rating from -21°F to +221°F supports hot oil pours and cold storage.
• Smooth interior discourages residue buildup for cleaner transfers.

Why choose a nitrile rubber funnel over a plastic funnel?

Nitrile rubber (NBR) offers flexibility and toughness that many rigid plastics lack, so it won’t snap under stress or become brittle after exposure to heat and hydrocarbons. The FlexAll funnel remains pliable for angling into tight openings and resists tearing when pushed into awkward service positions.

• Single-piece molding eliminates seams that trap dirt and leak.
• Flexibility allows safe insertion into angled fill necks without deformation.
• Durable construction reduces need for frequent replacement, unlike inexpensive plastic funnels.
• Designed to block residue buildup for consistent pours over time.

Will this funnel work for professional garage or fleet use?

Yes — the FlexAll is built to meet the demands of repeated daily use in professional environments. Its long reach and wide mouth make it practical for fast refills, while the robust nitrile compound endures frequent exposure to harsh fluids.

• 4-inch diameter mouth supports high flow to speed oil changes.
• 12-inch length reaches recessed fillers and deep transmission ports.
• Proudly USA-made by TEC Products, reflecting shop-grade quality and consistency.
• Smooth interior reduces cross-contamination and simplifies cleaning between jobs.

How do I use and maintain the FlexAll funnel for longest life?

Use the funnel for transferring the recommended fluids, avoid contact with strong caustics not listed in compatibility, and rinse after each use to prevent residue buildup. Store away from direct UV and extreme heat to preserve the nitrile material properties.

• Rinse with mild detergent and water after use; air dry before storing.
• Avoid prolonged exposure to ozone or open flames to prevent premature aging.
• Inspect for nicks or tears; replace if compromised to avoid leaks.
• Keep in a toolbox or hang in the bay for quick access during service.

Who this is for: The TEC Products FlexAll Long Flexible Oil Change Funnel is ideal for home mechanics, professional technicians, fleet maintenance crews, and restoration hobbyists who need a resilient, reusable funnel that handles a wide variety of automotive fluids. If you value a tool that bends into position, resists chemical attack, and speeds common fluid changes with minimal mess, the FlexAll is a straightforward, shop-ready choice.
