Keep the DEF filler tube and reservoir on your Duramax or Power Stroke free of contaminants with the PPE DEF Filler Cap.

OEM-like internal threads seat the cap exactly like the original, and an internal O-ring seals the filler neck against moisture and debris. The fluted outer profile gives a secure grip for on and off with gloves or wet hands.
