Hydraulic Hose Selection & Hose Types | Professional Guide – Hidroman
The performance and safety of hydraulic systems are directly related to the right hydraulic hose selection. Choosing the wrong hose not only reduces equipment performance but also increases maintenance costs and can even pose risks. In this comprehensive blog post, we will clearly discuss the key features, types, and selection criteria of hydraulic hoses. (Hidroman)
Why is Hydraulic Hose Selection Important?
Hydraulic hoses are designed to transmit high-pressure fluid power safely and efficiently to the system. Hose selection suitable for the usage area:
Improves system efficiency
Reduces downtime and maintenance costs
Ensures operational safety (Hidroman)
Choosing the right hose, especially in hydraulic systems operating under high pressure, is critical for both economic and safety reasons.
Types of Hydraulic Hoses
Below you can find common hydraulic hose series according to different pressure ranges, application areas and norms: (Hidroman)
- Low and Medium Pressure Hoses
1K Series – EN 857 1SC standard, suitable for low and medium pressure systems. (Hidroman)
The 1T Series – EN 853 1SN/R1AT is an ideal option for low and medium pressure return lines. (Hidroman)
- Medium and High Pressure Hoses
2K Series – Medium to high pressure resistant with two layers of steel braid. (Hidroman)
2T Series – EN 853 2SN/R2AT normed, used in heavy-duty hydraulic systems. (Hidroman)
GoldenSPIR / 4SH & 4SP – Spiral steel coiled high pressure hoses are preferred in demanding industrial applications. (Hidroman)
- Special Application Hoses
HARVESTER / 17 Series – Perfect for medium pressure applications in the agricultural sector. (Hidroman)
SUPERJET Series – Professional hoses designed for pressure washers. (Hidroman)
Things to Consider When Choosing the Right Hose
- Pressure Capacity
The maximum working pressure of the hose should be appropriate for the highest pressure the system will be subjected to while it is operating. (Hidroman)
- Operating Temperature
The system temperature range affects the elasticity, durability, and longevity of the hose. (Hidroman)
- Abrasion and Environmental Resistance
The outer coating material determines the resistance to UV, chemical and mechanical abrasion. (Hidroman)
- Application Field
In different sectors such as agriculture, construction, and industrial production, hose performance expectations vary. (Hidroman)
Conclusion: Smart Choice = Longevity & Cost
Choosing the right hydraulic hose, although it may seem a little more costly at first; It provides significant savings in the long run by reducing maintenance, malfunction and efficiency losses. Proper hose not only enhances system performance but also ensures operational safety. (Hidroman)
If you have any doubts about choosing a hydraulic hose, it is always advantageous to seek professional support based on critical parameters such as usage pressure, temperature range, and system type.
Why Should Hydraulic Hose Selection Be Done Correctly?
Hydraulic hoses are critical components that safely transmit high-pressure fluid within the system. An incorrectly selected hose;
Pressure losses
Sudden tornado bursts
System failures
Occupational safety risks
may cause. Therefore, hydraulic hose selection is not only based on size; It should be done according to pressure, temperature and application conditions.
7 Basic Criteria to Consider When Choosing a Hydraulic Hose
- Working Pressure
The maximum working pressure of the hydraulic hose to be selected should be higher than the pressure at which the system operates .
Tip: The
burst pressure of the hose should generally be 4 times the working pressure.
- Fluid Type (Hydraulic Oil Compatibility)
Hydraulic oil used;
Mineral oil
Synthetic oil
Biological oil
maybe. The inner tube of the hose must be chemically compatible with the fluid used.
- Operating Temperature
Hydraulic hoses work safely within specific temperature ranges.
Standard hydraulic hoses: -40°C / +100°C
High-temperature applications: +120°C and above
The wrong temperature range will cause the hose to harden and crack prematurely.
- Hose Diameter (Inner Diameter – Flow Rate Match)
The inner diameter of the hose should be selected in accordance with the system flow rate.
Very narrow diameter → Pressure loss
Very large diameter → Inefficient flow
The right diameter directly impacts system performance.
- Hose Reinforcement Structure
The internal structure of the hose should be selected according to the application pressure:
Single layer steel braided hoses (1SN/1SC) → Medium pressure
Double layer steel braided hoses (2SN/2SC) → High pressure
Spiral steel coiled hoses (4SP/4SH) → Very high pressure
- Environmental Conditions
The environment in which the hose will operate also plays a critical role in selection:
Open area / UV ray
Chemical contact
Wear and friction
Agricultural, construction, industrial environments
Outer cover suitable for these conditions should be preferred.
- Standards and Norms
The selected hydraulic hose must necessarily comply with international standards:
EN 853 / EN 857
ISO 18752
SAE 100 R series
These standards guarantee the safe and long-lasting operation of the hose.
