How do I know which bend angle or tube length is right for my custom project?

Choosing the right bend angle or tube length depends on your specific build and space requirements. Measure the route for your exhaust, intake, or coolant line, then match the closest bend angle (30°, 45°, 60°, 90°, 135°, or 180°) and tube length we offer (100cm or 30cm). If you’re unsure, grabbing a variety of common bends can help you mock up your setup before welding or final assembly.

Are these stainless and aluminium bends compatible with most vehicles?

Yes, our high-grade 316 stainless steel and aluminium bends and tubes are designed to fit a wide range of automotive applications, including custom builds, repairs, exhausts, intakes, and coolant lines. They're trusted by both professional shops and DIY builders for use in cars, trucks, and performance vehicles. Just match your desired diameter and angle to your system for a great fit.

Do these bends and tubes come already polished or finished?

All of our stainless and aluminium bends and tubes are supplied with a premium, smooth finish. This makes them ideal for both visible installations and high-performance applications. Stainless parts have a clean, polished look, while aluminium pieces arrive with a raw, brushed finish ready for welding or custom finishing.

How easy is it to install these bends and tubes on my own?

Our products are precision-manufactured for an easy fit and leak-free connections. With basic fabrication tools and skills, you can cut, weld, or clamp them into your custom setup. For best results, double-check your measurements before installation, and use quality clamps or welding techniques for secure, durable joints.

Will these stainless and aluminium bends resist rust or corrosion over time?

Absolutely! Our bends and tubes are made from 316-grade stainless steel or high-quality aluminium, both chosen for their excellent resistance to rust and corrosion. They're built to handle harsh automotive environments, including under-the-hood heat and wet conditions, giving you long-lasting performance and reliability.

Stainless & Aluminium FAQ

What makes your stainless and aluminium bends and tubing ideal for custom automotive projects?

Our stainless and aluminium bends and tubing are engineered specifically for custom automotive fabrication. Made from premium 316-grade stainless steel and high-quality aluminium, they offer exceptional corrosion resistance, system reliability, and optimal fluid flow. These materials are lightweight and durable, perfect for building or upgrading exhaust, intake, or coolant systems. Whether you're a racing enthusiast or working on a classic car restoration, our range of bend angles and tube lengths gives you the flexibility and quality you need for a professional finish.

How do I choose between stainless steel and aluminium bends for my application?

Choosing between stainless and aluminium bends depends on your project's specific needs. 316-grade stainless steel bends and tubes are best if you need maximum corrosion resistance and strength, like in exhaust systems or high-temperature applications. Aluminium bends and tubes are lighter, making them excellent for intake and coolant systems where weight savings matter. Both options are durable, but if you're working in an environment with extreme heat or exposure to harsh elements, stainless steel may be the better option. If you need help matching the right material to your project, our team is happy to offer guidance!

Are your tube bends compatible with other Proflow and standard automotive components?

Absolutely! Our stainless and aluminium bends and tubing are designed to be compatible with Proflow aluminium tubing and most standard exhaust and intake components. The outer diameters and wall thicknesses meet common automotive fabrication standards, so you can use them seamlessly with a wide variety of clamps, couplings, and joiners. If you need specific sizing information to ensure a perfect fit, please check each product's detailed specifications or contact us for advice.

Can I install these stainless and aluminium bends and tubes myself, or do I need a professional?

Our bends and tubing are designed with both professional fabricators and DIY automotive enthusiasts in mind. With basic fabrication tools such as a tube cutter, a welder (for stainless), and appropriate joiners or silicone couplers (for aluminium), you can install these parts in your custom setup. If you're comfortable with automotive fabrication, installation should be straightforward. For high-precision applications or complex systems, professional installation is recommended to ensure proper sealing and alignment.

How durable are your stainless and aluminium bends and tubes for long-term automotive use?

Durability is one of our top priorities. Our 316 stainless steel tubing is highly resistant to rust, heat, and chemicals, making it ideal for demanding automotive environments and long-term performance. The aluminium bends and tubes, while lighter, also offer excellent corrosion resistance and strength, especially in less extreme environments. When installed correctly, both materials provide reliable performance and maintain their looks over time, giving you peace of mind and lasting value for your custom fabrication project.
