In service terms, that means a hose built around dimensional accuracy, vibration control, and pressure handling for diesel engine plumbing. Searches for Volvo and Mack hose replacement parts often lead to this part number, especially when matching the 3.5-inch ID and 6-inch centerline length.

This part cross-references 5MD4456M and 45MD384M for the same application.

Common Problems This Hose Can Address

• Charge-air leaks at a worn or cracked intercooler hose
• Boost loss caused by hose separation or ring-retention wear
• Vibration-related stress in turbocharger plumbing
• Rotational shock transfer in heavy-duty diesel engine systems
• Fitment issues when replacing a hose with the same 3.5 in. ID and 6 in. centerline length

Installation Notes and Tips

Verify the inside diameter, centerline length, ring count, and pressure requirement before installation. Match the hose to the existing turbocharger or intercooler routing on the vehicle, and inspect adjoining pipes, clamps, and sealing surfaces for wear before reassembly. For Volvo and Mack diesel service work, confirm the original hose dimensions against the removed part to ensure the Gates 26201 is the correct replacement.

Quality Assurance

Gates manufactures this hose for heavy-duty diesel service with a ring-retained construction intended to preserve design integrity under turbocharger operating conditions. The part is built to the listed dimensional and pressure specifications for charge-air system replacement work.
