Why Use a Tight Radius PTFE Fitting?

Standard 90-degree hose ends sometimes require more clearance than modern high-performance engine bays can provide. A tight-radius fitting allows sharper routing angles while reducing hose stress and simplifying installation around turbochargers, fuel rails, radiators, firewall clearances, and intercooler piping.

Translation: fewer kinked hoses and slightly fewer emotional breakdowns during installation.

Features

• High-flow internal passage design
• Suitable for fuel, oil, coolant, and transmission systems

[Size] Thread Size of 6AN PTFE Fitting is nine/16-18UNF.

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 End best work with PTFE fuel line. The 90 degree design is more compact and perfect for small areas.

Built for PTFE/Teflon Hose Systems

PTFE hose systems provide superior resistance to fuel permeation, pressure breakdown, and chemical corrosion compared to standard rubber-lined hoses. These fittings are specifically engineered to properly seal PTFE inner liners for long-term reliability under demanding conditions.

Because regular rubber hose and E85 eventually become enemies.

Perfect for Tight Engine Bay Routing

The compact tight-radius design is ideal for crowded engine compartments where standard AN fittings may interfere with intake manifolds, turbo systems, frame rails, or radiator components.

Especially useful when your turbocharger already occupies the same amount of space as a small household appliance.

[Parameter] Working pressure: 1500PSI. Temperature vary: -40°F-250°F. The PTFE fittings are anodized for sturdiness, anti rust and anti corrosion.
[Seal] The AN facet is sealed by a 37 degree angle, the fittings is precision-machined to exact tolerances for bother-free performance.
[Material and Feature] Manufactured from aluminum alloy 6061-T6. 360° Swivel design for simple assembly.

Designed for Modern Performance Fuels

Compatible with gasoline, E85, ethanol blends, methanol, race fuel, oil, coolant, and transmission fluid systems, this fitting supports modern high-flow fuel systems and aggressive tuning combinations.

Basically designed for builds where fuel consumption resembles industrial equipment operation.

Durable Billet Aluminum Construction

The billet aluminum body offers lightweight durability while resisting corrosion from harsh fluids and extreme engine bay temperatures. The black anodized finish also provides a clean motorsports-inspired appearance.

Because leaking fittings and rusty hardware are terrible visual modifications.
