PPE Polished Stainless Coolant Bypass Tube - Water Pump to Thermostat Housing (2006-2010 GM 6.6L Duramax) - (119000730
Overview
Upgrade the factory coolant bypass tube on your 2006-2010 GM 6.6L Duramax with the PPE Polished Stainless Coolant Bypass Tube. Designed to replace the OEM mild steel tube, this high-quality stainless version eliminates corrosion issues and provides long-term cooling system reliability.
Premium 304 Stainless Steel Construction
PPE builds this tube from fully polished 304 stainless steel, offering superior resistance to rust and coolant contamination compared to the factory steel component. The polished finish adds durability and a clean, upgraded look under the hood.
Precision CNC-Machined Tube End
A CNC-machined tube end ensures a precise fit with the factory water pump and thermostat housing, improving sealing performance and installation accuracy.
Includes Viton O-Rings
The bypass tube comes with two Viton O-rings, which offer excellent resistance to heat, pressure, and long-term compression set - far outperforming standard rubber O-rings.
Why Replace the OEM Tube?
The original mild steel tube is prone to internal rust, which can contaminate the cooling system and eventually lead to leaks. Factory O-rings also harden over time, increasing the risk of failure. PPE's stainless steel upgrade eliminates these weak points and ensures consistent, dependable performance.
