Frequently Asked Questions
What is the VIB10707 used for?The VIB10707 is a straight female-to-female -20AN union adapter used to connect two -20AN female-threaded lines or components inline. Common applications include large-diameter oil return lines, fuel supply lines, and custom plumbing in high-flow forced induction builds where -20AN fittings are required.
What material is the VIB10707 made from?The VIB10707 is machined from 6061 aluminum alloy and finished in black anodize. This construction provides a good combination of light weight, corrosion resistance, and strength for typical automotive fluid plumbing use.
Is this fitting compatible with braided stainless hose ends?Yes. The VIB10707 uses standard -20AN 37-degree flare thread geometry, which is compatible with all standard AN hose ends and braided line assemblies in the -20 size.
Can the VIB10707 be used for fuel lines?Yes. The 6061 aluminum construction and smooth bore interior are suitable for fuel line applications. Ensure all fittings and hose material in the assembly are rated and compatible with the specific fuel type being used, including ethanol blends if applicable.
Is this fitting available in silver or any other finish?The Vibrant Performance female AN flare union adapter line is available in black anodized finish only. If a natural aluminum finish is required, check Vibrant's current catalog for alternative fitting options in the -20AN size.
What is the thread pitch on the VIB10707?The VIB10707 uses the standard AN/JIC 37-degree flare thread geometry. For -20AN, this corresponds to a 1-5/16-12 thread specification. Always verify thread compatibility with your connecting components before assembly.
Is the VIB10707 suitable for use with coolant lines?Aluminum AN fittings are generally compatible with coolant systems in performance builds. Verify that all other components in the coolant circuit are similarly rated and that the installation does not mix incompatible metals in a way that promotes galvanic corrosion.
How do I install an AN union adapter without leaks?Clean all threads before assembly and hand-tighten the fitting finger tight before using a wrench. AN 37-degree flare connections seal on the flare face, not on the threads. Over-tightening can damage the flare seat and cause leaks. Follow standard AN assembly torque practices and pressure test the system before operation.
Installation Overview
- Inspect the VIB10707 and both mating fittings for any damage or debris before assembly.
- Thread one side of the adapter onto the first fitting or component finger tight.
- Use an appropriate AN wrench to tighten to standard AN assembly torque, being careful not to overtighten and damage the flare seat.
- Connect the second fitting or hose end to the opposite end of the VIB10707 and repeat the tightening process.
- Pressure test the completed assembly before returning the system to normal operation to verify a leak-free installation.
