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.

Can you use regular AN fittings on a PTFE hose?

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.

Is PTFE the same as Teflon?

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.

Is PTFE plastic or rubber?

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.

Great bright light

Amazing lights! Beam is bright and wide. The price can’t be beat. Handles heat great, the separate block handles heat better than the all in one. I have ran multiple brands, my friends run the Ultra 3 and these blow them out of the water.

Gas lines

Very happy with the look and the install. Takes a bit to figuring out the pieces you need. I wished they sold the stainless steel hose and black fitting in a kit. I hade to buy separately. Getting the parts to fit up wasn’t too bad. Figuring the right adapters was a bit tricky.
