The Better Bypass Tube for Your Duramax

Enhance the reliability and style of your 2001-2005 GM 6.6L Duramax with the PPE Coolant Bypass Tube (Polished). Designed to outperform and outlast the wearer, inferior stock component, this bypass tube connects your factory water pump to the thermostat housing with precision and durability. Unlike the OEM mild steel tube that's prone to rust and eventual leaks, this polished stainless steel upgrade resists corrosion and adds a sleek, professional look under your hood. With this upgrade, your 6.6L Duramax enjoys improved dependability and peace of mind, knowing your cooling system is built to last.

Engineered for Durability

Crafted from fully-polished 304 stainless steel, this bypass tube offers superior strength and resistance to wear. The CNC-machined tube ends ensure a perfect fit and seamless integration with your factory water pump, maintaining optimal coolant flow and efficiency. To prevent leaks, the kit includes two premium Viton O-rings that provide a reliable, long-lasting seal. Built for durability and precision, this bypass tube is a smart investment to keep your Duramax running cooler and more efficiently for years to come.
