A reliable intake tract ensures consistent boost pressure, improving combustion efficiency, reducing fuel consumption, and lowering emissions, contributing to significant operational savings for fleet managers.

Trusted by operators in more than 60 countries, the Shacman WP12 Compressor Pipe Group is a global benchmark for heavy‑duty intake duct reliability. Its proven design and robust construction make it a cornerstone of modern commercial vehicle powertrains.

The rubber hose is manufactured from high‑grade silicone or EPDM with a reinforcement layer of aramid or polyester, providing exceptional flexibility, heat resistance, and dimensional stability. Its smooth internal bore minimises airflow restriction, while its precisely moulded ends ensure a tight fit over the pipe connections.

The clamps are manufactured from stainless steel or zinc‑plated carbon steel with a worm‑drive or spring‑loaded mechanism, providing a secure, even clamping force that prevents leakage and resists loosening under vibration. Their rounded edges prevent damage to the hose, ensuring a long service life.

The group is supplied with all necessary hardware for a direct replacement. Detailed torque specifications are provided for the clamps to ensure proper installation and long‑term reliability.

This compressor pipe group is an essential component for maintaining turbocharger performance and engine breathing. Regular inspection of the hose for cracks, swelling, or chafing is recommended, and replacement of the entire group is advised if any signs of wear or leakage are detected. Its genuine Shacman quality ensures that your engine continues to deliver maximum power and efficiency.

Clamp – A robust fastening device that secures the rubber hose to the compressor inlet and outlet connections, ensuring a leak‑tight seal under high boost pressures and vibration. Manufactured from high‑grade stainless steel or zinc‑plated carbon steel with a worm‑drive or spring‑loaded mechanism, this clamp provides a uniform clamping force around the hose circumference. Its design allows for easy installation and adjustment with a screwdriver or socket, accommodating thermal expansion and hose ageing. The clamp’s smooth inner edges prevent damage to the hose surface, while its corrosion‑resistant finish ensures long‑term durability in harsh under‑hood environments. This clamp is essential for preventing air leaks that can cause boost pressure loss, reduced engine power, and increased fuel consumption. It is a direct replacement for the original factory clamp, offering identical fit and clamping characteristics. Regular inspection for tightness and corrosion is recommended, and replacement is advised if the clamp shows signs of wear, rust, or loss of tension. Proper torque application is critical to avoid over‑tightening, which can damage the hose, or under‑tightening, which can lead to leaks.

rubber hose – A flexible, reinforced connector that carries pressurised air from the air cleaner or intercooler to the turbocharger compressor inlet. Manufactured from high‑grade silicone or EPDM rubber with a reinforcement layer of aramid, polyester, or steel wire, this hose provides exceptional heat resistance (up to 200°C), ozone resistance, and dimensional stability. Its smooth internal bore minimises airflow restriction, while its precisely moulded ends ensure a tight fit over the pipe connections. The hose is designed to withstand boost pressures up to 4 bar and is resistant to oil vapour, fuel, and coolant. Its flexibility allows for slight misalignment between components, reducing stress on the connections. This rubber hose is a direct replacement for the original factory component, offering identical flow characteristics and durability. It is critical for maintaining a leak‑free intake tract and ensuring consistent boost pressure delivery to the engine. Regular inspection for cracks, swelling, or chafing is recommended, and replacement is advised if any signs of wear or damage are detected. Proper installation with clean, dry surfaces and correct clamp torque is essential for long‑term reliability.
