The hose and fittings are nice quality. Their ability to get stuff shipped out quickly dose not happen.

Positive-Seal O-Ring Fittings to AN Male
Seal metric straight-thread (positive-seal O-ring) ports to AN plumbing—clean, leak-free, EFI-ready. Available in M14×1.5, M16×1.5, and M18×1.5 to AN-6 or AN-8 male.
- Positive-seal O-ring interface for reliable, serviceable connections on metric ports.
- Direct to AN: adapt to AN-6 or AN-8 for modern PTFE hose plumbing.
- Perfect for EFI upgrades & swaps: fuel filters, fuel rails, regulators, and sending units.
- Machined aluminum construction with anodized finish (fitting-safe when used with aluminum wrenches).
Sizes & options
| Metric Thread (Positive-Seal) | AN Male Outlet | Typical Use* |
|---|---|---|
| M14 × 1.5 | AN-6 or AN-8 | Fuel filter/rail, compact modules |
| M16 × 1.5 | AN-6 or AN-8 | Fuel filter housings, regulators |
| M18 × 1.5 | AN-6 or AN-8 | High-flow fuel modules, rails |
*Representative examples. Verify thread size/pitch on your specific component before ordering.
Where these adapters shine
- Factory fuel filters with metric O-ring ports → convert to AN for PTFE hose.
- Fuel rails & regulators during EFI conversions or LS/LT swaps.
- Fuel sending units & modules when re-plumbing return or feed lines.
Install tips:
- Confirm thread size and 1.5 mm pitch (M14/M16/M18). Check with a thread-pitch gauge.
- Lightly oil the O-ring. Thread in by hand to avoid cross-threading, then tighten until the O-ring seats. Do not over-torque.
- Adapt the AN male to your system with PTFE AN hose ends and hose bundles.
- Pressure-test after assembly. Replace any worn or nicked O-rings.
Important: For fuel system use. Not for brake or power steering circuits.

FAQs
Is this an ORB (SAE) fitting?
No—these are metric straight-thread fittings that seal with a positive-seal O-ring (M14×1.5, M16×1.5, M18×1.5). Match the thread and pitch on your component.
Which AN size should I choose?
AN-6 is the most common for EFI feed/return lines; use AN-8 where higher flow is needed. Keep AN size consistent with the rest of your system.
Do these include an O-ring?
Yes a fresh O-ring that matches the metric port groove and fuel compatibility. Inspect and replace any worn O-rings during service.
