About the EVIL ENERGY 3AN-20AN Fitting Wrench Set
Struggling with slipping adjustable wrenches or marked-up aluminum hose fittings? The EVIL ENERGY 8-piece AN fitting wrench set provides dedicated 3AN through 20AN sizes for steadier contact during assembly and removal. Lightweight aluminum construction makes the tools easier to carry between jobs. It suits professional mechanics, race-team technicians, and DIY builders servicing fuel, oil, brake, and other compatible AN plumbing in garages, workshops, paddocks, and custom-vehicle projects.


3AN-20AN Compatibility for Common Hose Fittings and Adapters
The set covers 3AN, 4AN, 6AN, 8AN, 10AN, 12AN, 16AN and 20AN fitting sizes. Use the corresponding wrench for compatible AN hose ends, adapters and pipeline connectors found in fuel-line maintenance, oil-system plumbing, automotive modification and racing brake-line repair. AN labels describe the intended fitting family; always compare the fitting's hex-flat measurement and manufacturer specification before use.

Five Benefits of the EVIL ENERGY Fixed-Size AN Wrench Kit
-
Eight Common AN Sizes: One kit covers 3AN through 20AN for a wide range of vehicle plumbing jobs.
-

-
Aluminum Construction: Lightweight, corrosion-resistant tools are easier to transport while remaining suitable for repeated garage and trackside work.
-
User-Friendly Open-End Design: Smooth wrench surfaces and accessible openings support comfortable fitting, installation and removal in practical work areas.
-
Workshop-to-Paddock Versatility: Suitable for mechanics and DIY builders working on compatible fuel, oil, brake and other AN plumbing systems.
Fixed-Size Wrenches Help Protect Aluminum AN Fittings
Using a wrench that fits the intended AN fitting more closely helps distribute turning force across the hex flats. This can reduce slipping, corner damage and surface marks that may occur when a poorly adjusted general-purpose wrench is used. Keep the wrench square to the fitting and avoid exceeding the fitting manufacturer's torque specification.

Lightweight Aluminum Tools for Garage and Trackside Work
The aluminum construction balances portability with the strength needed for routine hose-end assembly and service. The eight marked sizes make it easier to select the correct tool without repeatedly resetting an adjustable wrench, whether the job is at a workbench, inside a garage, or beside a race vehicle.

How to Select the Correct AN Fitting Wrench Size
- Identify the AN size specified for the hose end, adapter, or connector.
- Verify the fitting's hex-flat dimension against its manufacturer's specification. AN line size alone does not guarantee identical external wrench flats across every brand or fitting design.
- Select the matching marked wrench and confirm full, square contact before applying force.
- Use a second suitable wrench when the assembly requires counter-holding, and tighten only to the fitting manufacturer's recommended torque.
