Cummins 6B Engine Parts for Australia - Exhaust Section

Cummins 6B Exhaust System Components

The Cummins 6B engine, widely recognized for its durability and adaptability in both marine and industrial settings, relies on a high-performance exhaust system to manage engine gases, reduce backpressure, and maintain efficiency. A well-maintained exhaust system is critical not only for power output but also for fuel economy, emissions compliance, and overall engine longevity.

Diesel Pro Power supplies a comprehensive range of Cummins 6B exhaust components, from water-cooled marine manifolds to precision-machined gaskets, bolts, insulation materials, and industrial-grade mufflers. Each part is manufactured or sourced to meet OEM specifications, ensuring a perfect fit and long service life.

Marine Water-Cooled Exhaust Manifold for Cummins 6B

Marine applications demand specialized exhaust solutions due to the corrosive nature of seawater and the unique space constraints of engine rooms. The Cummins 6B marine water-cooled exhaust manifold is designed to transfer exhaust heat into the cooling water stream, keeping engine bay temperatures manageable and improving safety.

Key benefits of the marine manifold include:

• Corrosion resistance – Manufactured from high-grade materials capable of withstanding continuous saltwater exposure.

• Temperature control – Integrated water-cooling channels reduce surface heat, protecting surrounding components.

• Noise dampening – Reduces exhaust noise for a quieter operation on board.

This manifold is designed exclusively for marine use and should be paired with compatible gaskets, mounting bolts, and insulation wraps for optimal performance.

Exhaust Manifold Mounting Hardware

An exhaust manifold is only as reliable as the hardware that secures it. Diesel Pro Power supplies high-tensile screws and bolts engineered for the Cummins 6B, 6BT, and 6BTA platforms. These fasteners are also compatible with certain 4B engine configurations, offering versatility for mixed fleets.

Features of our manifold mounting hardware:

• Exact sizing – Metric threads and lengths precisely matched to Cummins specifications.

• High-temperature durability – Engineered to resist stretching and loosening under extreme heat cycles.

• Versatile use – Some bolts also double for alternator bracket and refrigerant compressor mounting in marine configurations.

Exhaust Manifold Gaskets for Cummins 6B

A properly sealed exhaust system ensures optimal turbocharger performance, prevents harmful gas leaks, and maintains backpressure at OEM levels. Cummins 6B exhaust manifold gaskets are precision-cut from heat-resistant materials that maintain integrity even under prolonged high-load operation.

Advantages of quality manifold gaskets:

• Leak prevention – Protects against exhaust gas escape, which can cause power loss.

• Thermal stability – Withstands high exhaust temperatures without deformation.

• Easy installation – OEM-matched hole patterns for quick alignment and secure fit.

Turbo Mounting Gaskets

For 6B engines fitted with water-cooled turbochargers, a specialized turbo mounting gasket is essential. These gaskets seal the interface between the turbo and the manifold or adapter, preventing leaks that can impair boost efficiency and reduce engine power.

Heat Management Solutions for Cummins 6B Exhaust Systems

Manifold Insulation Tape

Heat management is vital in both marine and industrial engine rooms. Manifold insulation tape helps maintain safer ambient temperatures, protects nearby wiring and hoses, and can extend the lifespan of exhaust components by reducing thermal cycling stress.

Available in multiple widths, insulation tape:

• Retains heat within the exhaust stream to improve turbo efficiency.

• Reduces crew exposure to high surface temperatures.

• Minimizes radiant heat damage to surrounding components.

Exhaust Flanges and Gaskets

Industrial Cummins 6B installations may require 4-inch exhaust manifold flanges and matching gaskets. These components ensure a secure, leak-free connection between the manifold and the rest of the exhaust piping.

• Flanges – Machined for precise alignment and durable weld compatibility.

• Gaskets – High-temperature materials maintain seal integrity even under fluctuating load conditions.

Mufflers and End Caps for Industrial Applications

While marine engines typically rely on water-cooled exhaust to control noise, many industrial Cummins 6B installations require traditional mufflers to meet noise regulations. Diesel Pro Power offers heavy-duty mufflers designed for industrial engine exhaust systems, available with threaded pipe connections for quick installation.

Muffler caps are also available in multiple diameters to protect against debris ingress when engines are stored or transported.
