Why Use PTFE-Specific Hose Fittings?

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

Translation: fuel leaks are expensive motivation to buy the correct fittings the first time.

[Size] Thread Size of 6AN PTFE Fitting is nine/sixteen-18UNF.

Features

• 6AN straight hose end fittings
• 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
• Includes 2 fittings per kit

[Application] The PTFE Hose Finish best work with PTFE fuel line.

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

[Parameter] Working pressure: 1500PSI. Temperature vary: -sixty five°F-252°F.

Straight Design for Maximum Flow

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

Because not every hose needs to resemble a geometry final exam.

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.

[Seal] The AN aspect is sealed by a 37 degree attitude.

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 combinations.

Basically designed for builds where fuel consumption resembles industrial machinery 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 leaking fittings and rusty hardware are terrible engine bay accessories.

[Material and Feature] Made from aluminum alloy 6061-T6. 360° Swivel design for simple assembly.
