2001-2026 GM 6.6L Duramax 304 Stainless Steel Coolant Tube (pump to oil cooler)

Specifically designed for use in conjunction with the factory oil cooler filter housing. This coolant pipe is custom fabricated with a heavy-duty flange. 304 stainless steel construction prevents corrosion compared with OEM mild steel pipe which is prone to rusting and eventually leaking.
