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 can lead to leaks, poor sealing, or hose damage under pressure.

Translation: PTFE fittings exist because “close enough” becomes a fire hazard surprisingly quickly.

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 4 fittings per kit

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

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 PTFE Hose Finish simplest work with PTFE fuel line.

Straight Design for Maximum Flow

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

Because not every hose routing problem requires advanced trigonometry.

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

Perfect for Modern Performance Fuels

PTFE hose systems resist fuel permeation and chemical breakdown far better than traditional rubber-lined hose. These fittings are compatible with gasoline, E85, ethanol blends, methanol, race fuel, oil, coolant, and transmission fluid systems.

Especially important because modern ethanol fuels treat cheap rubber hose like expired spaghetti.

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

Built for High-Performance Systems

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

Basically designed for cars where fuel consumption resembles commercial aviation.

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 engine bay accessories.

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