EVIL ENERGY 10AN Male Flare to -10 Female Swivel with 1/8"

EVIL ENERGY's AN10 male to -10 female swivel take-off adapter lets you add a fuel pressure gauge or sensor inline without cutting or replacing fuel lines.

Installed between AN10 fuel fittings, this compact aluminium adapter provides a 1/8" NPT gauge port for monitoring fuel pressure. Machined from 6061‑T6 aluminum and sealed using the AN 37° flare and tapered NPT thread design, the fitting is intended for automotive and motorsport fuel systems where an inline pressure readout or sensor mount is needed. It accepts the common 8AN flare thread (7/8-14 UNF) and supports swivel installation to ease hose routing.

How will this adapter let me fit a fuel pressure gauge quickly?

The adapter provides a dedicated 1/8" NPT port so you can screw in a mechanical gauge or electronic pressure sensor without fabricating a tee or cutting lines. The swivel design lets the mating -10 female rotate for correct orientation of the gauge or sensor, simplifying installation in tight engine bays.

• Direct 1/8" NPT port for standard gauge or sensor threads.
• AN10 male to -10 female swivel for easy alignment.
• Use PTFE or appropriate sealant on the NPT for leak-free sealing.

Is this adapter durable enough for high‑pressure fuel systems?

Yes — the fitting is machined from 6061‑T6 aluminum, offering strong corrosion resistance and reliable strength in automotive environments. It's rated for a maximum working pressure of 1,500 PSI and a wide operating temperature range, making it suitable for most gasoline and racing fuel system uses.

• Material: lightweight, high-strength 6061‑T6 aluminium.
• Max working pressure: 1,500 PSI for robust performance.
• Operating temperature range: -40°F to 250°F for varied conditions.

What sealing practices and thread details should I follow?

The AN flare end seals at a 37° flare angle, forming a metal‑to‑metal seal when properly tightened. The 1/8" NPT gauge port uses a tapered 60° thread and requires PTFE tape or thread sealant to ensure a leak‑free connection for liquid or vapor under pressure.

• AN thread: 37° flare, 8AN thread size 7/8-14 UNF.
• NPT port: tapered 60° thread — use PTFE tape or sealant.
• Recommended: tighten to spec and test under pressure after installation.

How does the swivel feature help during installation?

The swivel -10 female portion allows rotation independent of the fixed AN male, so you can orient the gauge or sensor to any convenient angle without twisting the fuel hose. This reduces stress on fittings and makes final alignment faster, especially when access is limited.

• Swivel female reduces hose twisting and simplifies routing.
• Enables precise gauge orientation in confined spaces.
• Speeds up install and reduces risk of hose strain or leaks.

Who this is for: technicians, performance tuners, and DIY enthusiasts who need a compact, high‑pressure take‑off point to install a fuel pressure gauge or sensor in AN10-equipped fuel systems. If your vehicle uses AN10 fittings and you want a reliable, reusable adapter to monitor pressure without modifying lines, this EVIL ENERGY aluminium take‑off fitting is engineered for that purpose.
