How Do I Identify the Correct Hydraulic Hose for My Application?

Selecting the right hydraulic hose is essential for ensuring safe, reliable, and efficient operation in industrial, manufacturing, and mobile equipment environments. The correct hydraulic hose supports system integrity, minimises downtime, and helps you comply with industry standards.

Below we cover key factors, technical considerations, and best practices for hydraulic hose selection.

For further in-depth technical support and product details, visit our hydraulic hose selection guide.

Understanding Hydraulic Hose Types and Applications

Hydraulic hoses are engineered for a range of pressures, temperatures, and fluid types. Begin by identifying your application’s requirements, including the type of machinery, operating environment, and hydraulic fluid in use. Common applications range from construction and agricultural equipment to manufacturing lines and mobile plant systems.

When selecting a hose, consider whether your system is stationary or mobile, the frequency of movement, and exposure to abrasion, vibration, or environmental hazards. For specialist environments, Flextech provides hoses with enhanced covers, anti-static properties, and custom reinforcements.

Flextech offers a comprehensive range of hydraulic hoses for low, medium, and high-pressure applications. For an overview of available options, see our hydraulic hose selection guide.

Determining System Pressure Requirements for Hydraulic Hoses

Pressure rating is a critical factor in hydraulic hose selection. Identify your system’s maximum working pressure and ensure the hose you choose meets or exceeds this rating, with a suitable safety margin. Consider both continuous operating pressure and any pressure spikes or surges that may occur during operation.

For high-pressure applications, such as hydraulic lifts or heavy-duty machinery, select hoses specifically rated for those conditions. Detailed pressure ratings are available in the hydraulic hose selection guide.

Always check for temperature derating as well. As the temperature increases, the hose’s pressure rating may decrease. Use manufacturer derating charts to ensure safe operation.

Matching Hydraulic Hose Size and Flow Rate

Proper sizing of the hydraulic hose is essential for efficient fluid transfer and system performance. Hose size is determined by the internal diameter (ID), which must match the required flow rate and minimise pressure loss.

Undersized hoses can cause excessive heat, reduced efficiency, and increased wear, while oversized hoses may add unnecessary weight and cost. Use manufacturer flow charts and sizing calculators, or consult Flextech’s technical team for support.

For more on sizing, refer to our hydraulic hose selection guide.

Selecting the Right Hydraulic Hose Material and Construction

Hydraulic hoses are constructed from materials such as synthetic rubber, thermoplastics, PTFE, and reinforced steel wire. The choice depends on the fluid type, temperature, pressure, and environmental exposure. For example, high-temperature applications may require hoses with special synthetic rubber compounds or PTFE linings, while abrasive environments may need hoses with extra protective covers.

Flextech supplies hoses with multiple reinforcement layers for added strength and durability. For further guidance, see our custom hose assemblies.

Assessing Temperature Range and Environmental Conditions

The operating temperature of both the hydraulic fluid and the surrounding environment affects hose performance and lifespan. Select hoses that can handle the minimum and maximum temperatures your system will encounter.

If your equipment operates outdoors, consider hoses with UV, ozone, and weather-resistant covers. For extreme environments, such as those with chemical exposure or high abrasion, choose hoses designed for those specific hazards.

Ensuring Fluid Compatibility in Hydraulic Hose Selection

Hydraulic hoses must be compatible with the fluids they carry, including mineral oils, synthetic fluids, water-glycol solutions, and biodegradable fluids. Incompatible hoses can degrade, swell, or fail prematurely. Always check compatibility charts and confirm with the manufacturer.

Flextech provides a chemical compatibility guide to help you select the right hose for your fluid type.

Choosing the Correct Hydraulic Hose End Fittings

End fittings are critical for secure, leak-free connections. Select fittings that match your hose type, pressure rating, and system requirements. Options include BSP, NPT, JIC, SAE, and DIN threads, as well as flanged, quick-release, and custom connections. Proper fitting installation is essential to prevent leaks and ensure system integrity.

For guidance on fittings, see our end connections overview.

Routing, Bend Radius, and Hose Assembly Length

Correct routing and bend radius are vital for hydraulic hose longevity. Here’s some top tips:

  • Avoid tight bends, kinks, and twisting, as these can cause premature failure.

  • Follow manufacturer recommendations for minimum bend radius and allow for movement and vibration.

  • Measure hose assemblies accurately, accounting for fitting length and installation path.

For best practices, refer to our hydraulic hose selection guide.

Compliance, Certification, and Industry Standards

Hydraulic hoses must comply with recognized industry standards such as EN 853, EN 856, SAE J517, and ISO 1436 to ensure quality and safety. These standards establish rigorous requirements for pressure ratings, flexibility, durability, and resistance to environmental factors. Compliance guarantees that the hoses have undergone thorough testing and meet the performance criteria necessary for reliable operation in demanding hydraulic systems.

We recommend always requesting certification and detailed documentation for your hose assemblies to verify compliance, support quality assurance, and facilitate traceability throughout the hose’s service life.

Maintenance, Inspection, and Hydraulic Hose Asset Management

Regular inspection and maintenance are critical to ensuring the safety, reliability, and optimal performance of hydraulic hoses. During routine checks, carefully examine hoses for any signs of wear, abrasion, leaks, bulging, or other visible damage that could indicate impending failure.Even minor issues can quickly escalate, so it is important to replace hoses at the first sign of deterioration or according to the manufacturer’s recommended service intervals. Consistent maintenance helps prevent costly downtime, equipment damage, and safety hazards.

Additionally, maintain thorough records of all inspections, maintenance activities, and replacements in your asset management system. This documentation supports compliance with industry regulations, facilitates proactive maintenance scheduling, and enhances traceability throughout the hose’s lifecycle.

Flextech’s hose asset management programme can help you manage hose registers and inspection schedules.

Pressure Testing and Hydraulic Hose Safety

Before installation and at regular intervals throughout their service life, hydraulic hoses should undergo pressure testing to verify their integrity and ensure compliance with safety standards.

Hydrostatic testing, conducted at 1.5 times the hose’s designated working pressure, is the recommended method to identify any weaknesses, leaks, or defects that could compromise performance. This rigorous testing helps prevent unexpected failures and enhances system reliability.

Always request official test certificates from your supplier or testing facility, and maintain detailed records of all pressure tests. Keeping these records up to date is essential for audit readiness, regulatory compliance, and effective asset management.

Flextech offers hose inspection and testing to ensure your hoses meet industry standards.

Selecting Hydraulic Hoses for Special Environments

Some applications require hoses with unique properties, such as anti-static, flame-retardant, or low-temperature flexibility. For example, mobile plant equipment may need abrasion-resistant covers, while food and pharmaceutical facilities require hoses with FDA or EN 12115 compliance.
