GM 6.6L Duramax Coolant Bypass Tube

The OEM mild steel tube is prone to rust, which can lead to coolant system contamination and eventual leaks. Over time, factory O-rings also tend to harden and lose compression, increasing the risk of failure. PPE’s upgraded bypass tube is specifically designed to work with the factory water pump and is crafted from high-grade 304 stainless to prevent corrosion and ensure reliable, long-term performance.

Frustrated At First

Was about to return this product, thinking it was faulty after trying to install this 3 times and could not get it to seal. The O-rings that they provided ended up being too small to seal correctly in the thermostat housing, so I ended up picking up a thicker o ring from ace hardware and it worked great. Otherwise, the bypass pipe is great quality, and I would buy again.

Fixed My Problem!

PPE's Bypass Tube saved the day for me. Built out of sturdy stainless steel, this tube did bend, like the original from GM. I would jighly recommend this product to anyone.

Great quality part

Delivery was prompt, received within a few days of ordering. Very good quality part, welded together instead of crimped like original. Stainless is a definite plus at less than half the cost of a GM one. Fit right on with no problem.
