Hydraulic Hose Pressing: An Expert Technical Guide from Selection to Application
Introduction: Why Hydraulic Hose Pressing is Critical
Hydraulic hoses are at the heart of high-pressure systems. While factors such as the right hose selection, oil properties, and operating conditions are vital,The connection point where the hose meets the union — i.e., the pressing — is the real critical step for system performance and reliability. In the given article, hydraulic hose types and selection criteria are discussed in detail; Here on this foundationTechnical pressing knowledge, standards, errors and solution suggestionsWe will add it.

What is Hydraulic Hose Pressing?
Hydraulic hose pressing is the permanent joining of the hose and the fitting. This is intended to:
Leak-proof and secure connection
Minimal flow loss
Maximum durability
Resistance to vibration and pressure impact
The pressing process involves a specialhydraulic hose press machineand must be made within standard tolerances. (Hidroman)
Press Machine and Technical Specifications
How Does a Press Machine Work?
Hydraulic hose press machines ensure that the fitting fits homogeneously in the hose under high pressure. The workflow is as follows:
Key technical parameters when selecting a press machine:
Maximum pressing diameter
Jaw opening width
Die set compatibility and variety
Pressing speed and control precision
These criteria are critical for both production capacity and suitability for hose type. (Hidroman)
Pressing Die Selection: Technical Steps
The pressing die should be selected according to the hose-fitting combination. Consequences you may encounter with the wrong mold selection:
Mold Selection Error
Possible Outcomes
The mold is too big
Loose connection, leakage
The mold is too small
Hose deformation, inner layer damage
Suitable mold but wrong pressure
Gland ovalization, flow section distortion
The right approach:
Mold selection according to the crimp diameter value determined by the manufacturer
Precise adjustment with calibration card or digital panel
Post-press measurement (with caliper)
Standards and Tolerances
The pressing process should be done in accordance with the standards. Many manufacturers specify the tolerance values in their pressing tables. These tolerances are usually:
From 0 / -0.2 mm to 0 / -0.6 mm(varies according to diameters) (Hidroman)
These values directly affect the system performance and reliability of the press process.
Common Pressing Mistakes and Solutions
???? Common Mistakes
Error
Conclusion
Wrong mold selection
Leak, hose slippage
Insufficient tightening
Connection looseness
Overtightening
Fitting cracking
Lack of calibration
Measurement error
✔️ The Right Approaches
Selection of press size according to standard tables
Recording measurements on digitally controlled machines
Quality inspection of sample joints after each pressing
Maintenance and Testing of the Pressed Hose
Controls that can be done after pressing:
Tightness verification by pressure test
Dimensional control (micrometer, caliper)
Deformation control by visual inspection
Additionally, regular maintenance of press machines is essential for long-term performance. Surface cleaning, lubrication and periodic wear control of the molds increase success. (Hidroman)
