Stop fighting warping and dirty welds. The DRP O2 Sensor Heat Sink and Purge Plug is the ultimate dual-purpose fabrication tool. Engineered to act as both a heavy-duty heat sink and an efficient backpurge plug, this tool eliminates warping and keeps your welds clean.
Why Choose the DRP Purge Cap?
-
Maximum Heat Dissipation: Machined with additional heatsink grooves that aggressively pull heat away from the weld zone. This cooling efficiently prevents warping.
-
Flawless Argon Distribution: Comes equipped with a diffuser fitting that evenly disperses argon around the 02 bung, eliminates turbulence, and ensures complete coverage to prevent oxidation ("sugaring")
