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

In this review of the FlexAll Long Flexible Funnel the bottom line is simple: this is a heavy-duty, flexible funnel meant for anyone who routinely pours automotive fluids and wants a reliable, reusable tool. The reviewer found the single-piece nitrile construction gives a noticeably sturdier feel than thin plastic funnels and the 16 in length with a 5 in mouth makes it easy to reach awkward fills while keeping spills to a minimum. For DIY mechanics, lawn equipment owners, and shop techs who value durability and chemical resistance, this funnel earns its place in a toolbox.

Key Features

• Flexible nitrile construction: The chemical-resistant NBR material stays flexible while resisting common automotive fluids for clean, controlled pouring.
• Long reach: The 16 in length allows access to deep or recessed filler openings without leaning hoses or awkward extensions.
• Generous mouth: The 5 in diameter mouth reduces splashback and makes it easier to pour from larger containers or jugs.
• Single-piece, heavy-duty build: Molded as one piece to avoid seams or weak spots, improving longevity compared with rigid plastic funnels.
• Trim-to-fit outlet: The outlet can be cut to the preferred diameter or length so it adapts to different filler necks and hoses.
• Wide fluid compatibility: Works with engine oil, diesel, gasoline, ATF, gear oil, hydraulic fluid and ethylene glycol antifreeze within a -21F to 221F operating range.

Who It's For

The FlexAll funnel is ideal for home mechanics, small shop owners, and property owners who service mowers, generators, and vehicles and want a reusable, solvent-resistant funnel that stands up to frequent use. Its sizeable mouth and long flexible neck suit pouring from jugs and cans without splashing.

It is less necessary for someone who only occasionally tops off windshield washer fluid or buys disposable funnels for one-off jobs; if minimal cost and single-use convenience matter more than long-term durability, a cheaper disposable funnel may be sufficient.
