FlexAll Long Flexible Funnel 16 x 5 in Yellow - Durable Nitrile

In this review the FlexAll long flexible funnel is judged as a practical, heavy-duty tool for anyone who changes oil or handles automotive fluids regularly; the single biggest reason to buy is its nitrile rubber construction that resists chemicals and stays flexible where plastic funnels fail. The reviewer found it especially useful for controlled pours into tight filler necks and transmission openings, and it keeps residue from building up inside the tube, so it stays cleaner through repeated use.

Key Features

• Chemical-resistant nitrile: The nitrile rubber body stands up to engine oil, ATF, diesel, gasoline and common antifreeze for reliable long-term use.
• Large mouth and length: A 5 in mouth and 16 in length let the funnel capture and direct large volumes without splashing or having to reposition often.
• Single-piece, leak-proof build: Molded from one piece of NBR, it avoids seam failures and reduces residue buildup for neater transfers than many plastic funnels.
• Trim-to-fit outlet: The outlet can be cut to the desired diameter and length, so it adapts to tight filler necks or longer drop needs.
• Handle for control: The integrated handle gives better grip and control during pours, making spill-free refills easier even when pouring from heavy containers.

Who It's For

The FlexAll funnel is a good match for DIY mechanics, small shop technicians, lawn and garden owners, and anyone who regularly pours oil, gas or transmission fluid and needs a durable, adaptable funnel. Its chemical-resistant NBR material and 16 in reach make it suitable for many automotive and equipment tasks.

Those who need a rigid, narrow-mouthed funnel for precise laboratory-style metering or who prefer disposable plastic funnels for occasional, single-use jobs may want to look elsewhere; this product is intended as a reusable, heavy-duty tool rather than a disposable convenience.

Pros & Cons

Pros

• Stands up to chemicals and temperature extremes, so it lasts through many oil changes.

• Large mouth and long length speed up filling while the trim-to-fit outlet increases versatility.

Cons
