Why Use PTFE-Specific Hose Fittings?

PTFE hose requires specially designed fittings engineered to properly compress and seal the PTFE inner liner. Standard braided hose fittings are not compatible and may lead to leaks, hose damage, or pressure sealing failures.

Translation: PTFE fittings exist because gasoline escaping under pressure is generally considered bad.

Features

• 6AN straight hose end fitting
• Designed specifically for PTFE/Teflon hose
• Lightweight billet aluminum construction
• Black anodized corrosion-resistant finish
• Precision-machined sealing surfaces
• Leak-resistant PTFE compression sealing
• Straight-through high-flow design
• Compact lightweight construction
• Suitable for fuel, oil, coolant, and transmission systems

[Product Size & Parameter] Size: 6AN. Thread Size: 9/16-18 UNF. Working Pressure: 1500PSI. Working Temperature Range: -40°F-248°F. Style: Straight. Note: Please verify the hose size before purchase.

Common Applications

• EFI fuel systems
• Return-style fuel setups
• E85 and ethanol fuel systems
• Turbocharger oil feed and return lines
• Oil cooler plumbing
• LS swap fuel systems
• Drift and drag race vehicles
• Fuel cell installations
• Motorsport AN plumbing projects

[Application] The fittings assist connect and route fuel hoses in tight spaces. Only to be used with PTFE fuel lines for E85, alcohol, nitro, grab, nitrous, power steering, oiling, hydraulics, and vacuum applications.

Straight Design for Maximum Flow

Straight hose ends provide unrestricted flow and simplified routing for long hose runs, underbody plumbing, fuel cell installations, and open engine bay layouts.

Because not every fuel line needs to resemble advanced geometry homework.

Perfect for Modern Performance Fuels

PTFE hose systems offer superior resistance to fuel permeation and chemical breakdown compared to traditional rubber-lined hoses. These fittings are compatible with gasoline, E85, ethanol blends, methanol, race fuel, oil, coolant, and transmission fluid systems.

Especially important because modern ethanol fuels absolutely destroy cheap hose setups over time.

[Easy Installation] Require an AN adjustable wrench for installation. A 360° swivel design provides enough flexibility for simple assembly.
[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 for High-Performance Systems

The unrestricted internal flow path supports high-volume fuel delivery required by upgraded fuel pumps, large injectors, turbocharged applications, and aggressive tuning setups.

Basically built for cars where fuel consumption resembles industrial equipment operation.

Durable Billet Aluminum Construction

The billet aluminum body provides lightweight durability and corrosion resistance while maintaining a clean motorsports-inspired appearance. The black anodized finish also resists wear from harsh engine bay temperatures and fluid exposure.

Because rusty fittings and leaking fuel systems are terrible visual upgrades.

[Built to Last] The only-piece PTFE hose end fitting is constructed from lightweight 6061-T6 aluminum alloy, and a black anodized finish at the surface increases durability, anti-corrosion, and wear resistance.

Why Choose EVIL ENERGY?

EVIL ENERGY continues to provide enthusiasts with affordable PTFE plumbing hardware, AN fittings, and performance fuel system components. Their PTFE hose ends deliver reliable sealing performance, durable construction, and installation flexibility for both street-driven and race-focused applications.

Because rebuilding a leaking fuel system after final assembly is not the motivational journey anyone wanted.
