16AN Transmission Cooler Line 10ft Braided Hose - High Pressure Fit

In this review of the 16AN Transmission Cooler Line the bottom line is clear: this 10 ft braided hose is a practical choice for builders and DIY mechanics who need a flexible, high-pressure line for transmission, oil cooler, or fuel return duties. It stands out for its combination of a 22.22 mm inner diameter, durable nylon and 304 stainless steel braid, and a 350 PSI working pressure that suits many automotive systems. The reviewer found it especially useful where routing and bendability matter most.

Key Features

• Inner and outer diameter: The 22.22 mm inner diameter and 29.38 mm outer diameter deliver a consistent flow profile for transmission and cooler systems.
• Length: At 3 m (10 ft) the hose gives enough length for routing and trimming to fit custom installations without joining multiple pieces.
• Construction: Woven nylon cover over a 304 stainless steel braid and CPE synthetic rubber core combines flexibility with a race-inspired appearance.
• Temperature tolerance: Rated from -40oF to 248 oF, it handles cold starts and high engine-bay temperatures common in performance applications.
• Pressure rating: The 350 PSI working pressure tolerance makes it suitable for many transmission, oil return and cooler circuits that operate under moderate pressure.

Who It's For

This hose is aimed at automotive enthusiasts, tuners and shop technicians who need a flexible replacement or upgrade for transmission cooler lines, oil return lines, turbo cooler feeds, or general high-pressure routing in engine bays. Its braided appearance also appeals to those who want a neater, race-style finish.

It is less appropriate for users who require compatibility with E85 fuels or expect decades-long internal rubber stability without inspection, and those who need pre-terminated fittings - this product is a raw 10 ft length intended to be cut and assembled to suit specific fittings and adapters.

Pros & Cons

Pros

• High flexibility makes tight routing and clean installs much easier than rigid metal lines.
• Durable outer braid and CPE core offer good temperature and corrosion resistance for under-hood use.
• Generous 10 ft length allows trimming to size and reduces the need for couplers in many installs.

Cons

• Some users report long-term internal deterioration; internal longevity may vary and periodic inspection is advised.
• Not compatible with E85, so it is not a universal fuel hose for all modern ethanol blends.

Our Verdict

The 16AN Transmission Cooler Line is a solid, value-oriented option for anyone needing a flexible, high-pressure braided hose for transmission coolers, oil return, or turbo cooler lines. It delivers good heat and pressure tolerance and a tidy appearance, but buyers should plan for installation with compatible fittings and inspect the hose over time for internal wear if used heavily with aggressive fuels.

Frequently Asked Questions

Can this hose be cut to length?
Yes. The 10 ft length is intended to be trimmed to fit custom runs and works with standard AN fittings when assembled properly.

Is this hose compatible with E85 fuel?
No. The hose is compatible with many fuels including methanol and nitromethane, but it is explicitly not fit for E85.

What systems is this hose suitable for?
It is recommended for transmission cooler lines, oil return, fuel return, turbo cooler lines, brake and hydraulic applications where the specified temperature and pressure limits match the system.
