The ALLSTAR PERFORMANCE Aluminum Wrench -16AN is a single-ended hand wrench cut to fit the hex on -16AN aluminum hose fittings. It's built for the people who plumb fuel, oil, and coolant lines with braided hose and threaded ends, where a steel combination wrench would chew up soft anodized aluminum. The body is aluminum with a color anodized gold finish, so it grips the fitting without scratching it and stays easy to spot in a crowded toolbox. If you run AN-style braided lines on a race car, hot rod, or off-road build, this is the tool that turns the nut without leaving marks.
Aluminum-on-aluminum is the point here. A standard steel wrench will scuff and round the hex on an anodized fitting, while this softer aluminum tool spreads load across the flats and keeps the finish intact. The color anodizing serves double duty as size identification, so you can pull the -16AN out of a set by color instead of squinting at stamped numbers. It measures roughly 12 inches long, 4 inches across, and just over half an inch thick per published specifications, with a working weight near 0.41 lbs. The single-ended design keeps the head compact for reaching fittings in tight engine bays and along chassis routing. It works on common AN-style braided hose fittings from brands like Aeroquip and Earl's. Pair it with our AN wrench set if you run multiple line sizes.
Reach for this wrench any time you assemble, tighten, or back off a -16AN fitting on fuel cells, oil coolers, dry sump lines, or large feed hoses. Holding one wrench on the fitting and another on the hose end keeps both from spinning and protects the seal, which is why most plumbing jobs call for matched soft-jaw tools. It lives well in a pit cart or trackside toolbox where appearance and finish matter as much as torque. Browse the rest of our tools for fitting assembly, or check the multi-wrench if you'd rather cover several AN sizes in one tool.
It's sized for -16AN aluminum hose fittings. The single-ended head matches the hex flats on -16AN nuts and adapters used on braided hose ends. For other line sizes, you'll need the matching wrench in that AN size.
Steel wrenches are harder than anodized aluminum fittings and will scuff, mar, or round the hex over time. This aluminum wrench is softer than the fitting, so it turns the nut and protects the finish, which matters on visible plumbing and reusable fittings.
The gold anodizing is a size-identification code. AN wrenches are color anodized so you can grab the right size at a glance instead of reading stamped numbers, which speeds up work when you're running several line sizes on one build.
It's a fitting assembly tool for braided AN-style hose plumbing. Use it to tighten or loosen -16AN fittings on fuel, oil, and coolant lines while holding the hose end with a second wrench so neither part spins and damages the seal.
