209-6477 76.2 mm ID Aftercooler Hose
Cat® Aftercooler Air Line Hose
Description
The aftercooler air line hose is used in the cooling system of air compressors or other machinery with an aftercooler. An aftercooler is a heat exchanger that cools compressed air to lower its temperature before it is used in certain applications. To improve strength and pressure resistance, air aftercooler hose lines usually include reinforcement layers. They resist degradation or chemical reactions that could affect the performance or life of the hose line.
Features
- Enables it to withstand high pressure and resist bursting.
- Prevents static electricity buildup.
- Withstands 160 kPa pressure at a temperature of 125°C.
Applications
The hose connects the aftercooler to the air compressor, ensuring that compressed air is efficiently cooled before it is used in manufacturing equipment, pneumatic tools or other industrial processes.
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. |
