DPF Sensor Bung Repair in San Antonio, TX
Stripped or damaged bungs cause false readings, failed regens, and derate conditions.
The sensor bungs on your DPF are small but critical. A stripped, cracked, or cross-threaded bung throws off your pressure and temperature sensors — leading to failed regenerations, fault codes, and engine derates. DPF Resolutions SA repairs or replaces damaged bungs quickly so your system reads accurately and regenerates properly.
What Is a DPF Bung?
A bung is a threaded port welded into your diesel particulate filter housing. Sensors — including differential pressure sensors and temperature probes — thread directly into these ports to monitor filter performance. When a bung is damaged, the sensor can't seat correctly, causing air leaks, inaccurate readings, and regeneration failures.

How We Repair a Damaged Bung
Precision welding and re-threading — done right the first time
Inspect & Diagnose
We assess the bung condition — stripped threads, corrosion, cracks, or a missing bung entirely — and confirm the right repair method.
Remove Damaged Bung
The old or damaged bung is carefully extracted from the DPF housing without damaging the surrounding metal.
Weld New Bung In Place
A new bung is TIG-welded into the housing with a clean, leak-free weld bead — no shortcuts, no epoxy patches.
Thread & Verify Fit
Threads are chased and verified to accept the sensor correctly. We test fit before reinstalling.
Reinstall & Scan
The sensor is reinstalled and we run a full diagnostic scan to confirm no fault codes and proper sensor readings.
What We Do
Every bung repair includes a post-service diagnostic scan
Bung Re-threading
Stripped threads are re-cut to restore proper sensor seating and a leak-free seal.
Bung Replacement
Cracked or beyond-repair bungs are removed and new bungs are welded in at the correct position and angle.
Sensor Inspection
We inspect the sensors themselves for damage during the repair — catching issues before they cause a comeback.
Post-Repair Verification
After every bung repair we run a diagnostic scan to confirm sensors are reading correctly and the system is operating normally.
