BSPT Adapter Fitting -6AN To 3/8in - 19

The BSPT Adapter Fitting -6AN To 3/8in - 19 is an essential hydraulic and fuel line connector for custom automotive builds, performance fuel systems, and precision fluid transfer applications. This adapter bridges the gap between -6AN JIC male fittings and 3/8-inch BSPT (British Standard Pipe Tapered) female ports, making it ideal for engine bay modifications, turbo installations, and aftermarket fuel management systems. Whether you're upgrading a classic muscle car's fuel delivery or integrating modern performance components into an older platform, this fitting ensures leak-free connections where standard adapters fall short.

Constructed from durable aluminum alloy with precision-machined surfaces, the BSPT Adapter Fitting delivers reliable sealing under high-pressure conditions common to fuel injection and forced-induction applications. The -6AN side features the industry-standard 37-degree JIC flare geometry, which mates with conventional AN hose fittings, while the 3/8-inch BSPT side provides a tapered thread connection that seats directly into BSPT ports without additional washers or O-rings. At just 0.04 lbs with compact dimensions (3.55 x 0.9 x 4 inches), this fitting minimizes weight and engine bay footprint while maintaining structural integrity under vibration and thermal cycling—critical for long-term reliability in high-performance vehicles.

Mechanics and engine builders rely on this adapter when fabricating custom fuel rails, turbo feed lines, or coolant bypass circuits where metric or British fittings must interface with North American -6AN standards. It's particularly valuable for LS swaps, rotary conversions, and imported engine installations where OEM port sizes don't match aftermarket component threads. Installation requires no special tools beyond a standard wrench—simply apply thread sealant tape to the BSPT end and hand-tighten until snug, then secure with a wrench to prevent rotation. Ensure proper AN hose assembly on the -6AN side and verify all connections with a leak test before engine startup.
