Description
The engine air line hose is a component used to facilitate air delivery between the engine air pump and other related components in the engine system. The engine air pump (also called an air injection pump or secondary air pump) injects fresh air into the exhaust system to help burn unburned fuel and reduce emissions. It is important to choose a high-quality hose that meets the specific requirements of the engine and ensures reliable, effective operation of the engine air pump.
Features
- Enables it to withstand high pressure and resist bursting.
- Maximum temperature of the hose is 218.3°C.
- Proof test pressure of 620 kPa at 218.3°C.
- Minimum burst pressure of 930 kPa at 218.3°C.
Applications
The hose carries hydraulic oil to power different functions such as lifting, digging, pushing or steering.
Specifications
| Hose Warning | Improper selections of hose and coupling combinations will void warranties and may result in serious personal injury or death, property damage, or component and machine system failure. Cat® hose assembly products are designed and tested as a system to achieve a reliable connection, thus maximizing hydraulic system safety and dependability. It is also recommended that appropriate and properly maintained Caterpillar tooling is used to ensure hoses are crimped to specifications. Use of Caterpillar hose with other manufacturer's couplings or the use of Caterpillar couplings with other manufacturer's hose may result in the production of unreliable, unsafe or under-performing hose assemblies. It is not recommended or authorized by Caterpillar. For additional information see SAE J1273 section 6.3 and ISO 17165-2 section 6.3. |
