Exhaust Weld Bungs

The exhaust weld bung is often the smallest yet most critical component of a diesel aftertreatment system, providing the mounting interface for the various sensors in your exhaust stream. Over time, high heat and road salt cause NOx, EGT, and O2 sensors to seize within these bungs, frequently resulting in thread damage during removal.

Rather than replacing an entire DPF or DOC due to a compromised mounting port, our high-quality stainless steel weld bungs offer a cost-effective repair solution. We stock a comprehensive variety of sizes and flares, including M12 x 1.25, M18 x 1.5, and M22 x 1.5, designed to restore the factory-spec mounting for your emissions sensors and clear exhaust-related engine codes.

At DPF Super Store, we specialize in keeping your trucks on the road with practical, in-stock solutions. For repair facilities and fleets handling frequent sensor replacements, we offer the BK4522 Popular Bung Assortment, a conveniently labeled kit containing our top-selling bungs to eliminate the guesswork of thread matching.

Avoid the high cost of dealer replacements and the delays of international shipping by choosing Canada's diesel aftertreatment experts. Shop our complete selection of weld bungs today to ensure a professional-grade, leak-free repair.

If you need help, give us a call. Please have as much information as possible. Ideally, the sensor part number, or the thread pitch and size, as well as the flare.
