Why Choose One Piece PTFE Hose Fittings?

Traditional multi-piece hose fittings can be more difficult to assemble and may introduce unnecessary restriction or additional leak points. The one-piece full flow design improves installation simplicity while maximizing internal flow efficiency and sealing reliability.

Translation: less frustration and fewer fuel smells permanently living in your garage.

[Product Size & Parameter] Size: 6AN. Thread Size: 9/16-18 UNF. Working Pressure: 1500PSI. Working Temperature Range: -40°F-250°F. Angle: 90 Degrees. Note: Please verify the hose size before purchase.

Features

• 6AN 90-degree hose end fittings
• One-piece full flow design
• Compatible with PTFE braided hose
• Lightweight billet aluminum construction
• Black anodized corrosion-resistant finish
• Precision-machined sealing surfaces
• Compact 90-degree routing design
• High-flow internal passage design
• Includes 2 fittings per kit

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

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

[Full Flow Hose End] Precision CNC machined hose end fitting features very good wall thickness and achieves uninterrupted drift.

Perfect for Tight Engine Bay Routing

The compact 90-degree design helps route hoses cleanly around intake manifolds, turbochargers, radiators, firewall clearances, fuel rails, and intercooler piping while reducing hose stress and improving fitment flexibility.

Especially useful when your turbo kit already consumed all available engine bay space.

Built for Modern Performance Fuels

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

Because modern ethanol fuels absolutely destroy cheap hose setups over time.

[Anti-Leak Seal] On the AN side, there’s a 37-degree flare angle to form an entire seal without applying an extra sealing compound.

High-Flow Full Flow Design

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

Basically designed for builds where fuel consumption resembles industrial machinery.

Durable Billet Aluminum Construction

The billet aluminum body offers lightweight durability and corrosion resistance while maintaining a clean motorsports-inspired appearance. The black anodized finish also helps resist wear from harsh engine bay conditions.

Because rusty fittings and leaking fuel systems are terrible aesthetic choices.

[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.
