Dorman 55247 Intercooler Hose Clamp

Intercooler Hose Clamp for Ram Turbo Plumbing

Dorman 55247 is a high-performance intercooler hose clamp built for turbocharger pipes and hoses that need a more even sealing load than a flat OE clamp can provide. Its curved Powerband profile helps create a tighter seal on boots and pipes, while the stainless steel construction and low-profile spiral screw support installation in confined engine bays.

• Constant tension worm drive clamp design
• Patented curved Powerband profile for more uniform clamping force
• Stainless steel construction for corrosion resistance
• Low-profile spiral screw for tighter access areas
• Maximum diameter: 4.5 in.
• High-performance hardware for turbocharger hose and pipe sealing

Fitment and Application Details

Compatible with 2018-2021 Ram 2500 and 2018-2021 Ram 3500 applications using the Powerband 3.75-4.5 inch setup. This Dorman 55247 intercooler hose clamp is a direct-fit hardware solution for Ram turbo plumbing where maintaining boost pressure and sealing integrity matters. This part cross-references Mopar 68359596AA for the same application.

Use Dorman 55247 when replacing a worn or unevenly loading intercooler clamp on Ram 2500 and Ram 3500 turbocharger hoses. The curved band helps distribute force more evenly across the hose and pipe surface, which is important in boosted intake systems that see heat, vibration, and pressure cycling.

Common Problems It Can Help Address

• Boost leaks at intercooler hose connections
• Uneven clamping pressure from a flat OE-style clamp
• Loss of turbo pressure caused by poor sealing
• Clamp loosening in high-heat, high-vibration service
• Restricted access during service in tight engine compartments

Installation Notes and Tips

Verify hose and pipe diameter before installation and confirm the clamp range matches the 3.75-4.5 inch application. Position the clamp so the band seats evenly over the boot or pipe bead, then tighten the hex nut gradually to achieve uniform compression without distorting the hose.

Quality Assurance

Dorman OE FIX components are engineered as direct replacement hardware with application-specific improvements over the original design. Part number 55247 uses stainless steel construction and a curved band profile to support consistent sealing performance in turbocharger plumbing.
