FAQ'S

What are stainless coolant tubes and why use them in Peterbilt trucks?
Stainless coolant tubes are rigid metal coolant lines used instead of rubber hoses; they resist heat, corrosion, and vibration better, providing longer life in critical cooling circuit locations.

Are your stainless coolant tubes compatible with Peterbilt models?
Yes — our tubes are engineered to match the bends, diameters, and connector types typically used in Peterbilt cooling systems, making many of them drop-in replacements.

How do I select the correct coolant tube for my Peterbilt?
Match the length, bend radius, inner diameter, and type of connection ends. Comparing with your original tube or using OEM reference numbers helps ensure the right fit.

Can stainless coolant tubes fail or leak?
While stainless is very robust, leaks can occur at joints if clamps loosen or seals degrade. Careless bending or abrasion against other parts can also lead to damage.

Do stainless coolant tubes need special maintenance?
They require minimal maintenance—just regular checks for secure clamps, integrity of mounting brackets, and inspection for wear or abrasion over time.
