Collection: Speedflow Fittings - AN Fittings Hose Ends Adapters

Choosing the right Speedflow fitting series depends on your specific application. The 100 Series fittings are ideal for general performance use and are compatible with most fuel, oil, and coolant systems. The 200 Series offers additional strength and is typically used in high-pressure or severe environment setups, like racing or custom turbo builds. The 400 Series is designed for easy installation with push-lock hoses, making it perfect for DIY garage projects where quick assembly is a priority. If you’re unsure which series matches your hose or project requirements, check the product descriptions or contact our team for tailored advice.

Before purchasing, check the fluid type, operating temperature, and pressure requirements of your system. Speedflow hoses are designed for wide compatibility with most automotive fluids—including fuel, oil, and coolant. However, certain hoses (like Teflon lined) are better for aggressive fuels or high temperatures. Refer to the product specifications for each hose type, and if you’re unsure, contact us with your vehicle and fluid details. Using the matching Speedflow hose ends and fittings will ensure a leak-free and reliable connection.

Yes! Speedflow fittings are engineered for wide compatibility with most automotive fuel, oil, and coolant systems, whether you drive a classic muscle car, Japanese import, or a custom drag build. Their precision-machined threads and durable materials ensure a reliable, leak-free seal. Always double-check your vehicle’s hose size and thread type before purchasing. If you’re working on a specialty or rare model, reach out to SS Racetech Rods & Customs – we’re happy to help verify fitment for your setup.

Speedflow fittings stand out due to their high-performance engineering, superior materials, and corrosion resistance. Unlike generic fittings, these are made from premium-grade aluminum and designed to handle the rigors of high-pressure automotive systems – perfect for racers, performance tuners, and anyone expecting reliability and durability. Their leak-free connections and precision threads reduce installation headaches and help maximize fluid flow, giving you peace of mind whether you’re on the track or street.

Installing Speedflow fittings is straightforward but does require basic hand tools and some attention to detail. For the best results, use a set of aluminum AN wrenches to avoid scratching the anodized surface and to ensure proper torque. Prepare your hoses carefully and double-check fitment before tightening. The push-lock (400 Series) fittings make installation even easier—just lubricate the hose and push it on. If you haven’t installed performance fittings before, there are plenty of instructional videos available, or you can ask our team for a quick walkthrough.
