Components of the Cummins 5455103 Service Kit

V-Band Clamp (2835596)

The V-Band Clamp is a critical component in the 5455103 Service Kit, designed to securely connect and seal exhaust systems. Its role is to ensure a tight and reliable connection between exhaust components, preventing leaks and maintaining system integrity. The V-Band Clamp operates by using a band and a series of bolts to create a uniform clamping force around the exhaust components, ensuring a consistent seal ⁹.

Regular Hexagon Nut (3529372)

The Regular Hexagon Nut is an essential fastening component included in the service kit. It is used in conjunction with the V-Band Clamp to secure the exhaust system components. The hexagonal shape of the nut allows for easy tightening and loosening using standard tools, ensuring that the V-Band Clamp remains firmly in place. This nut plays a vital role in maintaining the structural integrity and sealing efficiency of the exhaust system ¹⁰.

O-Ring Seal (4041396)

The O-Ring Seal is a small yet crucial component in the 5455103 Service Kit. It is used to create a tight seal between mating surfaces within the exhaust system. The O-Ring is designed to withstand high temperatures and pressures, ensuring that the exhaust system remains leak-free. Its role is to prevent the escape of exhaust gases, which could lead to performance issues and increased emissions. The O-Ring Seal is typically placed in grooves or around ports where components connect, providing a barrier against leaks ¹¹.
