Single Male Banjo Adaptr Bolt M12x1.25 to -6AN

The Single Male Banjo Adapter Bolt M12x1.25 to -6AN from VIBRANT PERFORMANCE is a critical fluid line adapter designed for custom fuel, oil, and coolant system configurations in modified vehicles. This adapter bridges metric threaded ports (M12x1.25) to standard AN hose fittings (-6AN), making it indispensable for engine swaps, turbocharger installations, and custom fuel rail setups where factory port sizes don't match aftermarket component requirements. Whether you're building a street rod, upgrading a naturally aspirated engine to forced induction, or fabricating a complete fuel system from the ground up, this adapter ensures leak-free connections without modification to existing manifold or block ports.

Constructed with precision engineering, the banjo design allows fluid to flow through the center bolt while the adapter housing seals against the port opening—a proven geometry that distributes clamping force evenly and prevents thread stripping in soft aluminum castings. The M12x1.25 metric thread profile matches common OEM port sizes found on many late-model blocks and intake manifolds, while the -6AN outlet accommodates standard braided stainless or rubber hose with AN fittings. VIBRANT PERFORMANCE's manufacturing standards ensure dimensional accuracy and material durability; proper torque application (typically 15–25 lb-ft depending on port material) creates a reliable seal without requiring Teflon tape or thread sealant. The compact footprint (3.54 x 1.5 x 6.3 inches) and lightweight design (0.04 lbs) minimize interference with surrounding engine bay components.

Mechanics and fabricators favor this adapter for fuel pressure gauge installations, remote oil filter relocation kits, and turbo feed/return line integration on LS swaps, AE86 builds, and generational platform conversions. It's equally suited for coolant bypass routes in performance cooling upgrades and auxiliary fuel supply systems. Ensure your M12x1.25 port is clean and undamaged before installation; stainless or aluminum banjo bolts (not supplied) are required for corrosion resistance. Compatible with any -6AN hose assembly, this adapter eliminates guesswork and expensive custom porting work, delivering professional results for DIY builders and professional shops alike.
