Tube Sleeve Adapter -3AN Tube Size 3/16in

The Tube Sleeve Adapter -3AN Tube Size 3/16in from Vibrant Performance is a precision hose fitting adapter engineered for high-performance fuel, oil, and coolant line applications in modified engines and custom fuel systems. Designed for builders and mechanics working with braided stainless steel tubing, this adapter bridges the gap between -3AN AN fittings and 3/16-inch diameter tube, making it essential when consolidating multiple hose standards on a single project or upgrading factory rubber lines to aluminum or braided equivalents.

This tube sleeve adapter features a straightforward push-fit design with a barbed or sleeved interior that securely grips 3/16-inch tubing, while the -3AN male or female end connects directly to standard AN fittings, carburetors, fuel pressure regulators, oil coolers, and transmission lines. Vibrant Performance manufactures these adapters from aluminum alloy with precision machining to ensure tight tolerances and leak-free operation under pressure cycles. The compact 3.54-inch length and lightweight 0.01-pound profile make it ideal for tight engine bay installations where space is limited, and the anodized finish resists corrosion in high-temperature environments typical of turbo builds, LS swaps, and supercharged applications.

Street rodders, drag racers, and weekend warriors benefit most from keeping multiple sizes of these adapters on hand during fuel system retrofits, carburetor conversions, and hose routing modifications. Installation is straightforward: slide the 3/16-inch tubing fully onto the barbed sleeve until it seats against the shoulder, then thread the AN fitting end into your target component or manifold. Verify hose clamp security at the tube connection point to prevent slippage under vibration. This adapter is compatible with any fuel, oil, or coolant system using -3AN ports and works seamlessly with both mechanical and electronic fuel injection setups, making it an affordable, reliable solution for custom plumbing on track cars and street machines.
