Product Description
Designed for matching e85Freaks 350 Series PTFE fuel hose, this reusable straight swivel hose end creates a female AN 37° flare connection for pump gasoline, E85/ethanol, and compatible race-fuel systems.
The straight configuration provides a clean, direct connection when the PTFE hose can leave the fitting in line with the component or adapter it is attached to.

Unbranded by Design
The cleanest builds are often the ones where the plumbing disappears into the finished system.
That is why e85Freaks/JBtuned fittings are intentionally produced without exterior logos, laser-etched branding, or oversized manufacturer markings.
Performance builders often go to considerable effort to create a tucked, simplified engine bay where fuel and fluid plumbing is routed cleanly and kept visually unobtrusive. Repeated logos on every hose end and adapter draw attention back to the fittings themselves, adding visual noise to an area the builder may be trying to minimize.
Our logo-free exterior allows the fitting to blend into the plumbing instead. The hose routing, fabrication, engine, and overall build remain the focus rather than a collection of branded connections throughout the engine bay.
No oversized logos. No unnecessary markings. Just a clean, understated fitting that becomes part of the system instead of calling attention to itself.
Unbranded by design—because the fitting should complete your build, not compete with it.
For e85Freaks 350 Series PTFE Hose
This hose end is designed specifically for matching e85Freaks 350 Series PTFE AN hose. The PTFE hose and 350 Series hose end work together as a matched fuel-plumbing system.
350 Series PTFE hose ends are not compatible with 250 Series rubber-core hose. Matching AN sizes do not make the two hose-end systems interchangeable.
Likewise, do not assume that another PTFE hose is compatible simply because it carries the same AN size. PTFE hose construction and outside diameter can vary between hose systems.
PTFE Hose-End Construction
Unlike the reusable hose ends used with the 250 Series rubber-core system, the 350 Series uses a PTFE-specific compression and olive/ferrule-style termination designed around the construction of the matching PTFE hose.
This difference in hose construction is why the 250 and 350 Series use separate hose-end families even when the AN connection size is identical.
Why Choose a Straight Hose End?
A straight hose end is the simplest routing option when the hose can continue directly away from the connection without immediately changing direction.
This configuration works well where adequate clearance exists in front of the connection and the PTFE hose can follow a natural path without being forced into an immediate bend.
If the hose needs to change direction directly after the connection, choose an angled 350 Series hose end that better matches the required routing rather than forcing the hose into an unnecessarily tight bend.
Female AN 37° Flare Connection
The connection side of the hose end uses a female AN 37° flare. The connection seals at the mating flare surfaces rather than at the threads themselves.
Do not apply thread sealant to the AN flare connection. Verify that the mating fitting uses the correct AN size and 37° flare sealing style before assembly.
Reusable Swivel Design
The reusable design allows the hose end to be assembled onto matching 350 Series PTFE hose without permanently crimping the fitting to the hose.
The swivel-style construction also allows the fitting to be properly clocked during assembly for clean routing and easier alignment with the mating AN connection.
Built for E85-Compatible PTFE Fuel Systems
The e85Freaks 350 Series PTFE system is suitable for pump gasoline, E85/ethanol, and compatible race fuels, giving builders a fuel-hose system that is not limited to gasoline-only use.
E85-compatible plumbing does not by itself make a vehicle flex fuel. True flex-fuel operation requires an appropriate ethanol-content sensor, compatible wiring or electronics, engine-management support, and proper ECU configuration and tuning.
Select the Correct AN Size
Select the hose-end size that matches both the e85Freaks 350 Series PTFE hose and the AN connection being used.
- -4AN
- -6AN
- -8AN
- -10AN
- -12AN
- -16AN
AN size alone does not determine hose compatibility. Always match the fitting to the correct hose family and size.
Matching 350 Series PTFE Fuel Hose
Pair this hose end with e85Freaks 350 Series Nylon Braided PTFE Fuel Hose for a matching reusable PTFE fuel-line assembly.
Need a Different Routing Angle?
The e85Freaks 350 Series PTFE hose-end family is available in multiple routing configurations, including Straight, 30°, 45°, 60°, 90°, 120°, 150°, and 180°. Choose the angle that allows the hose to follow a natural path without unnecessary bending or interference with nearby components.
Important: This is a 350 Series PTFE hose end. It is not compatible with e85Freaks 250 Series rubber-core hose.
