FAQs about PTFE Fittings

What are PTFE fittings?

PTFE fittings are specialized hose fittings designed for PTFE (Teflon) braided hoses. Unlike standard rubber hose fittings, they can handle higher pressure, extreme temperatures, and aggressive fuels like E85. Evil energy fittings use a 37° flare seal and 360° swivel design to provide a secure, leak-free connection. These fittings are ideal for performance automotive fuel, oil, and turbo systems.

No. Regular AN fittings are not designed for PTFE hoses. PTFE hoses require evil energy ptfe fittings, which use a specific compression design to ensure proper sealing and prevent leaks. Using the wrong fittings can cause poor connections, leaks, or even hose damage.

Yes, PTFE (Polytetrafluoroethylene) is the chemical name for Teflon. Ptfe fittings are designed for this material because it’s heat-resistant, non-stick, and highly durable. Evil energy fittings built for PTFE hoses can withstand high pressure and temperature, making them perfect for demanding automotive builds.

PTFE is a type of engineered plastic, not rubber. It’s known for its exceptional chemical resistance and temperature stability. That’s why evil energy PTFE fittings are designed specifically for PTFE hoses — they provide a more secure, longer-lasting seal compared to traditional rubber hose fittings.

Evil energy fittings are made from 6061-T6 aluminum with a black anodized finish for strength and corrosion resistance. PTFE fittings from EVIL ENERGY offer leak-free 37° flare sealing, high-pressure resistance, and excellent compatibility with gasoline, diesel, and E85 fuels. Whether for turbo builds, oil systems, or fuel upgrades, evil energy PTFE fittings deliver reliable performance trusted by builders worldwide.
