Why Use PTFE Hose for Your Hot Rod Build? Technical Benefits & Pro Tips

So, you’ve heard about Hot Rod AN LLC and all this PTFE hose buzz? Great—let’s dive into the details and explain why PTFE braided hose is the best option for your fuel system, transmission lines, and more.

What Is PTFE Hose?

PTFE stands for Polytetrafluoroethylene—a big word, but for good reason. It’s the same base material as the popular trademarked name Teflon™. PTFE is an incredibly versatile, chemically inert material, ideal for high-performance plumbing in automotive applications.

Top 5 Reasons to Choose PTFE Hose from Hot Rod AN LLC

1. Vapor Barrier & Odor Elimination

PTFE hose acts as a vapor barrier, preventing fuel odors from seeping into your garage or shop. Say goodbye to that lingering gasoline smell!

2. Superior Chemical Resistance

Modern fuels, including ethanol blends like E85, can eat away at traditional rubber hoses. PTFE fuel line resists degradation, keeping your plumbing leak-free for the long haul.

3. Wide Temperature Range

Our PTFE hose is built to withstand extreme conditions—ranging from -60°C to over +200°C. Ideal for engine bays, trans lines, and high-temp zones.

4. High Pressure Ratings

• AN6: Rated to 2,500 PSI
• AN8: Rated to 2,000 PSI
• AN10: Rated to 1,500 PSI

More than enough for EFI systems, oil lines, and boost builds.

5. Lifetime Warranty

All PTFE hose and PTFE hose end fittings from Hot Rod AN LLC come backed by a Lifetime Warranty against manufacturing defects.

Customize Your Look

Choose from a variety of outer braid options to match your style. Whether you go with Stainless Steel for a classic pro look, or opt for black nylon with colored checks (silver, red, blue, green, orange, yellow, or purple), we’ve got the vibe for your ride.

Did you know? Even our nylon braided hose still features a stainless steel inner braid under the color wrap—style AND performance.

Things to Know About PTFE Hose

1. PTFE Hose Requires PTFE Fittings

PTFE hose uses a ferrule-style seal. Always pair your hose with our Hot Rod AN PTFE fittings to ensure a perfect fit and seal.

2. Mind the Bend Radius

PTFE hose is stiffer than rubber and can kink if bent too sharply. For best results, consult our AN hose sizing guide and allow adequate room for proper routing.

3. Requires Precision During Cutting

Use the right PTFE hose install tools to avoid fraying or crushing the hose during assembly.
