Why Choose One Piece PTFE Hose Fittings?

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

Translation: fewer leaks and fewer late-night fuel-system rage sessions.

[Product Size & Parameter] Size: 10AN. Thread Size: 7/8-14 UNF. Working Pressure: 1500PSI. Working Temperature Range: -40°F-250°F. Angle: 90 Degrees. Note: Please verify the hose size before purchase.

Features

• 10AN 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 configuration
• High-flow internal passage design
• Includes 2 fittings per kit

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

Common Applications

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

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

Perfect for Tight High-Flow Routing

The compact 90-degree design helps simplify hose routing around intake manifolds, turbochargers, firewall clearances, fuel rails, radiators, and intercooler piping while reducing hose stress and improving installation flexibility.

Especially useful when your turbo setup already consumed every remaining inch of engine bay space.

[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 Modern Performance Fuels

PTFE hose systems offer superior resistance to fuel permeation, pressure breakdown, and chemical corrosion compared to standard rubber-lined hose systems. 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.

[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.

Designed for Massive Fuel Flow

The unrestricted full-flow internal design supports the demands of upgraded fuel pumps, large injectors, twin-pump systems, and aggressive high-horsepower tuning combinations.

Basically designed for cars that consume fuel with the urgency of a fighter jet.

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 helps resist wear from harsh engine bay temperatures and fluid exposure.

Because leaking fittings and rusty hardware are terrible performance modifications.
