The REDHORSE PERFORMANCE 8AN Dry Break Fittings (black) are valved quick-disconnect adapters built to break a -8 AN line without dumping fluid on the floor. This is the part you want when you run a remote fuel cell, a removable oil cooler, or a transmission cooler that has to come off between sessions. The fitting carries part number 4155-08-2 and installs inline of an existing AN assembly. Racers, engine builders, and anyone running a track-prepped car will recognize the value of a coupling that seals on disconnect at both halves. It pairs naturally with the rest of our fittings, hoses, and valves lineup.
Each adapter is machined from aluminum and finished in black anodize, with a fluorocarbon O-ring handling the seal. The configuration is a straight male plug in -8 AN thread, and the design is fully valved so flow stops on both ends the moment you separate the coupling. Disconnect is tool-free once installed: push both ends together, follow the precut channel, and the adapter parts cleanly. That spill-free action keeps fuel, coolant, and transmission fluid where it belongs instead of on your shop floor. The fluorocarbon O-ring stands up to fuel and oil exposure, which is why this style sees use across fuel systems, coolant circuits, and transmission lines. For the mating half and matching line ends, look at our 8 AN plug options and 8 AN straight hose ends.
Reach for these when a component has to come off the car repeatedly and you can't afford a mess each time. A removable fuel cell for tech inspection, a cooler that swaps between events, or a dyno cart that connects and disconnects all day are all good fits. Because both halves seal on separation, you avoid air in the system and lost fluid during the swap. Run the male -8 AN end into your assembly, mate it to its counterpart, and you're set. Build out the rest of the run with our 8 AN tee fittings and supporting hose.
Frequently Asked Questions
What does the dry break feature actually do?
The fitting is valved, so both halves seal the moment they separate. When you disconnect a -8 AN line, fluid stays in the system instead of spilling. Push both ends together and follow the precut channel to part the adapter, all without tools once it's installed.
What thread size and configuration is this fitting?
It is a straight -8 AN male plug, part number 4155-08-2. It installs inline of an existing AN assembly, so you adapt your current -8 AN line to a quick-disconnect point without rebuilding the whole run.
What fluids can this dry break adapter handle?
It uses a fluorocarbon O-ring, which holds up to fuel and oil exposure. The manufacturer lists fuel systems, transmission systems, and coolant systems as intended applications. That makes it a fit for removable fuel cells, oil coolers, and transmission coolers.
What is it made of?
The adapter is machined from aluminum and finished in black anodize. The anodized surface resists corrosion, and the aluminum body keeps the coupling light enough for inline use on a hose run.
Do I need both halves to use it?
Yes. A dry break coupling works as a mated pair. This -8 AN male plug connects to its counterpart to complete the quick-disconnect. Check our 8 AN plug and hose end listings to build out the matching side of the connection.
