TEC Products FlexAll 16" Nitrile Flexible Oil Change Funnel — 5" Mouth, Spill-Resistant for Automotive Fluids

TEC Products FlexAll is a 16-inch nitrile rubber flexible funnel made for spill-resistant oil, transmission, and coolant transfers during automotive service.

Engineered for garages and DIYers, this long, flexible funnel replaces brittle plastic funnels with a single-piece nitrile design that resists tearing, chemical attack, and residue buildup. With a 5-inch mouth and a tapered body, it keeps fluids flowing cleanly into tight filler necks and remote openings while tolerating temperatures from -21°F to 221°F.

How does FlexAll reduce spills and messes during oil changes?

The nitrile rubber construction maintains its shape while bending to reach awkward fill points, minimizing drips and splashes. Its smooth interior discourages residue from sticking, so fluids pass through without pooling or slow drips.

• 5" diameter mouth for steady catchment and reduced overflow
• 16" length to reach deep or recessed filler necks
• Single-piece manufacturing prevents seams where leaks can start

What kinds of fluids can I safely use with this funnel?

FlexAll is compatible with a broad range of automotive liquids: engine oil, diesel, gasoline, automatic transmission fluid (ATF), gear oil, hydraulic fluid, and ethylene glycol antifreeze. The nitrile (NBR) material resists many common chemicals and fuels without swelling or degrading.

• Suitable for oil, transmission fluid, coolant, fuel, and hydraulic fluids
• Temperature rated -21°F to 221°F for cold or hot service
• Non-reactive surface reduces contamination risk between uses

Will FlexAll last longer than typical plastic funnels?

Yes—nitrile rubber is far more flexible and tear-resistant than most molded plastics used in disposable funnels. The one-piece design means no glued or molded seams to fail, and the durable material tolerates repeated bends without cracking.

• One-piece NBR construction resists splitting and cracking
• Flexible body returns to shape; tolerates repeated use
• Smooth interior reduces trapped residue and eases cleaning

How easy is it to use and maintain in a busy shop?

FlexAll is lightweight, simple to rinse, and stores flat or rolled in a toolbox or drawer. Its size and flexibility make it quick to position for fast, efficient service without fumbling or holding awkward angles.

• Rinseable interior for quick cleanup between jobs
• Rollable compact storage for crowded workspaces
• Fits standard filler necks while extending reach to tight areas

Who this is for: TEC Products FlexAll is suited to professional technicians, independent mechanics, and home enthusiasts who want a dependable, reusable funnel for oil changes, fluid top-offs, and maintenance tasks. If you regularly handle multiple fluid types, work in tight engine bays, or prefer durable, USA-made shop tools, this nitrile funnel gives reliable, spill-reducing performance without the fragility of plastic alternatives.
