Normal Flare

If you’re repairing your heavy-duty emissions system and sensing the need for a stronger fit, the difference often comes down to the right weld-in component. At American Radiator, located in Des Moines, Iowa, we specialize in precision-engineered normal-flare DPF bungs built to handle high-heat, high-pressure environments in trucks, agricultural machines, and industrial equipment. These crucial components provide optimal sealing for sensors and ports in your diesel particulate filter (DPF) system—ensuring reliability and performance when it matters most.

When a standard sensor port fitting leaks or fails under stress—resulting in exhaust system errors, back-pressure issues, or downtime—a quality normal-flare weld bung makes all the difference. Our bungs are crafted from durable materials, have accurate thread pitches, and install cleanly and efficiently to avoid service interruptions. Every unit is designed with real-world durability in mind.

From fleet operations across Iowa to equipment in regional service centers, professionals trust American Radiator for valuable parts that deliver. With fast shipping, expert guidance, and commitment to quality, our normal-flare DPF bungs stand up to rugged conditions and keep your system running at its best.
