Finish Line Factory’s precision made, high quality AN to BSPP Adapters are ideal for the delivery of fuel, oil, water, air, or any fluid of your choice. CNC Machined using lightweight 6061 aluminum and anodized black for a slick finish. Our fittings provide strength in extreme conditions and are easy and fast to assemble. We only use high-quality seals and o-rings to provide a leak-free seal, especially when used with volatile liquids like racing fuels and some oils/coolants. Additionally, each of our fittings is given either a matte or polished finish to provide your vehicle’s fluid delivery system a quality look, feel, and performance. Please be aware that this is the parallel threaded version of the BSP standard.
