TEC Products Flexible Oil Change Funnel 12-inch Nitrile Long Funnel with 4-inch Mouth, Spill-Resistant

TEC Products FlexAll Long Flexible Oil Change Funnel is a 12-inch nitrile rubber funnel built to handle oil, transmission fluid, coolant and other automotive liquids without cracking or spilling.

Designed for mechanics and DIY vehicle owners, the FlexAll funnel replaces rigid plastic funnels with a single-piece nitrile rubber construction that flexes into tight fill points, resists fuel and oil deterioration, and stands up to temperature extremes. With a 4" mouth and a long tapered body, it helps transfer fluids cleanly and reduces drips and mess in the shop or driveway.

How does the FlexAll funnel prevent spills during oil changes?

The FlexAll funnel’s soft yet resilient nitrile rubber holds its shape while allowing controlled bending, so you can guide fluid into narrow or awkward openings without the funnel collapsing. The smooth interior reduces turbulence and slows flow for a steadier pour, minimizing splashes and waste.

• 4" wide mouth for easy pouring from jugs and pumps
• 12" tapered length reaches recessed fill ports
• Single-piece nitrile construction resists cracking and leaks
• Smooth interior reduces drip and splash

Which fluids is this funnel compatible with?

FlexAll is formulated from NBR (nitrile rubber), which tolerates a broad range of automotive liquids including engine oils, ATF, diesel, gasoline, gear oil, hydraulic fluids and ethylene glycol–based antifreeze. It works within a wide temperature band so it won’t harden in cold or soften excessively in heat.

• Safe for engine oil, transmission fluid, coolant, hydraulic fluids
• Gasoline- and diesel-resistant material for fuel handling tasks
• Operational temperature range: -21°F to +221°F
• Non-porous interior reduces residue buildup

How durable is the funnel compared with plastic alternatives?

Unlike brittle plastic funnels that crack or split after repeated use, the FlexAll’s nitrile composition resists tears, chemical attack and deformation. Its one-piece design eliminates seams and joints that typically fail, making it a longer-lasting tool for commercial garages or at-home maintenance.

• Single-piece molding prevents separation and leaks
• Nitrile resists fuels, oils and many solvents better than standard plastics
• Holds shape under repeated bending and use
• Proudly USA-made by TEC Products with quality controls

How easy is it to use and clean between jobs?

FlexAll’s flexible body lets you angle the spout to fit hard-to-reach openings while gravity does the work. After use, wipe or rinse the smooth interior—its non-absorbent surface discourages buildup, so it’s ready for the next fluid without prolonged soaking.

• Wipe-clean nitrile surface for quick maintenance
• Flexible shape fits tight fill locations and funnels into funnels
• Works with funnels, pumps, and bottle pour spouts
• Compact 12" length stores easily in tool kits or drawers

Who is this for? The TEC Products FlexAll Long Flexible Oil Change Funnel is aimed at automotive technicians, fleet maintenance staff, motorcycle and ATV owners, and any DIYer who performs routine fluid service. If you need a durable, flexible funnel that tolerates a wide range of fluids and temperatures and reduces mess on the job, FlexAll is a practical, long-lasting addition to your tool box.
