378-5355 119.4 mm OD Hydraulic Hose
Cat® 119.4 mm OD Hydraulic Hose
Description
Hydraulic hoses are used to transmit hydraulic power and fluid throughout the vehicle's hydraulic system. They transmit pressurized hydraulic oil from one component to another within the vehicle's hydraulic system. They are capable of carrying pressurized fluid from the power steering pump to the steering gear, making steering control easier. In suspension systems, hydraulic hoses are used in hydraulic shock absorbers or struts to provide vibration damping and stability by controlling the flow of hydraulic oil.
Features
- High-temperature-resistant design
- Designed for flexibility and durability.
- Withstands pressure differentials.
Applications
The hydraulic hose transmits hydraulic pressure from the master cylinder to the wheel cylinders or brake calipers, enabling the braking system to engage and control the speed of the vehicle.
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. |
