The Texas Speed Double Headed AN Wrench, 8AN and 6AN, is a specialty aluminum wrench with a -8AN end and a -6AN end for assembling and tightening AN hose ends and adapter fittings. Because the wrench is aluminum rather than steel, it is far less likely to scratch or gouge an anodized fitting than a standard open-end wrench, which keeps new fittings looking the way they did out of the package.
Texas Speed makes the wrench from 6061 aluminum with chamfered and contoured edges for a comfortable grip, and each wrench is stamped with its sizes so the right end is easy to pick out. The two sizes on this wrench cover the -6AN and -8AN fittings common on fuel feed and return lines, catch cans and oil lines. Texas Speed also offers a seven-piece double headed wrench set covering 3AN to 20AN.

FAQ
What sizes does the Texas Speed 8AN/6AN double headed wrench fit?
One end fits -8AN fittings and the other end fits -6AN fittings, so a single wrench covers the two sizes most often used on fuel feed and return lines, catch can lines and smaller oil lines.
Why use an aluminum AN wrench instead of a regular steel wrench?
A steel wrench can scratch or chew up the finish on anodized aluminum AN fittings. Texas Speed makes this wrench from 6061 aluminum so it tightens hose ends and adapters without marring the fitting surface.
Does this wrench work on any brand of AN fitting?
Yes. AN sizes are a standard, so the -8AN and -6AN ends of this Texas Speed wrench fit -8AN and -6AN hose ends and adapter fittings from any manufacturer, not just Texas Speed fittings.
How do I tell which end is which?
Each Texas Speed AN wrench is stamped with its sizes, so the -8AN and -6AN ends can be identified at a glance without measuring the fitting.
Is a full set of AN wrenches available?
Yes. Texas Speed offers a seven-piece double headed AN wrench set (TSP-3040) that covers 3AN through 20AN, for builders who need more sizes than the 8AN and 6AN on this single wrench.
