Flat Flare

If your diesel engine’s exhaust system is giving you trouble, even the smallest components can have a big impact — especially when your weld-in fittings aren’t built to last. At American Radiator in Des Moines, Iowa, we provide precision-engineered flat flare DPF bungs built for strength, durability, and exact fit. These weld-in fittings are designed to handle high-heat, high-pressure exhaust environments, ensuring a tight, leak-free seal for your diesel’s aftertreatment system.

When a DPF bung or sensor port starts to fail, it can lead to costly downtime and reduced engine efficiency. That’s why our flat flare weld bungs are made from heavy-duty steel with the correct thread pitch and flare design to maintain proper sensor alignment and exhaust flow. Each part is tested for precision and compatibility with major truck, ag, and industrial equipment brands.

At American Radiator, we understand how critical reliability is for fleet managers and owner-operators across the Midwest. That’s why we offer fast shipping, expert support, and trusted quality on every flat flare DPF bung we sell. Keep your emissions system running smoothly with durable components made to handle the demands of real-world performance.
