DPF Bung Repair Done Right.

Restore Your Filter—Don’t Replace It.

Over time, DPF sensor ports (known as bungs) can become stripped, cross-threaded, corroded, or damaged during removal. Instead of replacing your entire filter housing, we offer precise bung repair services that restore the port’s integrity—saving you time and money.

What’s a Bung and Why Does It Matter?

Bungs are welded ports on your DPF that house critical sensors—pressure, temperature, and NOx.

 

If these ports are damaged:

Our Bung Repair Process:

1. Removal & Inspection

We carefully remove the damaged bung and inspect the sensor port to assess whether it’s stripped, cross-threaded, or corroded.

2. Thread Repair or Cut

Depending on the damage, we re-thread the bung or make a clean cut to prepare the area for precise welding and sealing.

3. TIG-Welded Replacement

A new stainless-steel bung is TIG-welded into the housing to ensure strength, alignment, and long-term sensor compatibility.

4. Seal & Pressure Test

The repair is sealed and pressure-tested to confirm it’s leak-free, reliable, and ready for service on the road or in the shop.
