Why Choose a One Piece PTFE Fitting?

Traditional multi-piece hose fittings can be more difficult to assemble and may create unnecessary flow restrictions or sealing inconsistencies. The EVIL ENERGY one-piece full flow design improves installation simplicity while maximizing internal flow efficiency.

PTFE-compatible fittings are also critical for modern fuels like E85, ethanol blends, methanol, and race gas that can quickly degrade standard rubber hose systems.

Translation: fewer leaks, fewer headaches, less fuel smell permanently attached to your hoodie.

Common Applications

• EFI fuel systems
• Return-style fuel setups
• Turbocharger oil feed and return lines
• Oil cooler plumbing
• Catch can routing
• LS swaps
• Honda K-series and B-series builds

[Application] These fittings are ONLY used with PTFE fuel lines for E85, alcohol, nitro, grasp, nitrous, power steering, oiling, hydraulics, and vacuum applications. A 360° swivel design allows for simple assembly.

Perfect for Tight Routing Situations

The 45-degree fitting angle provides a clean compromise between straight and 90-degree hose ends, helping reduce hose stress and simplify line routing around radiators, intake manifolds, fuel rails, and firewall clearances.

Basically designed for engine bays where every inch disappeared after the turbo upgrade.

[Full Flow Hose End] Precision CNC machined hose end fitting features superb wall thickness and achieves uninterrupted glide.

Built for Modern Performance Fuels

PTFE hose systems are widely used in motorsports because they resist fuel permeation, pressure breakdown, and chemical corrosion far better than traditional rubber-lined hose systems. Pairing PTFE hose with proper full flow fittings ensures stable fuel delivery under aggressive conditions.

Especially important when your fuel system moves enough E85 to hydrate a small village.

[Anti-Leak Seal] On the AN side, there’s a 37-degree flare angle to form a whole seal without applying an extra sealing compound.
[Built to Last] The only-piece PTFE hose end fitting is made out of lightweight 6061-T6 aluminum alloy, and a black anodized finish at the surface increases durability, anti-corrosion, and wear resistance.
