Equipment for thermal sealing of hydraulic hoses

Thermal hose sealing devices are specialized workshop machines designed for the precise application of heat-shrink covers on the ends of hydraulic lines. These systems are a vital component of anti-corrosion prevention, creating a tight insulation barrier at the interface between the crimp ferrule and the hose's outer cover. Through controlled thermal processing, these devices eliminate the risk of moisture and aggressive media penetrating into the steel braid. Such solutions are essential in professional hose assembly shops that prioritize connection durability in accordance with rigorous operating standards. Correct use of these devices significantly increases the service life of hoses operating in extreme field conditions.

Application and technical characteristics

The operating principle of the devices is based on the uniform delivery of thermal energy, allowing for safe shrinkage of the covering material without the risk of thermal degradation of the synthetic rubber. In industrial environments where lines are exposed to HLP and HVI type hydraulic oils and mechanical contaminants, tight protection of the fittings is a technical requirement. These devices are fully compatible with a wide range of hoses, including 4SP hydraulic hoses, providing stable protection in the operating temperature range from -40°C to as high as +105°C. This process is a necessary supplement for complete lines assembled using professional hose crimping machines. The design of the devices allows for handling various diameters, making them versatile tools in the service of construction, agricultural, and industrial machinery. Temperature stability and precise control of operation time guarantee that the application of the cover will be free from defects such as under-shrinking or melting of the material.

Why choose our components?

• Compliance with service processes: The use of our devices allows for the standardization of the hose protection process, which is required for the production of lines in accordance with ISO standards for power hydraulics.
• Structural protection: Professional sealing prevents pitting corrosion, which is the primary cause of premature failure of steel braids in 1SN hose crimp ferrules.
• High energy efficiency: The devices have been optimized for energy consumption in continuous operation cycles, which translates into lower operating costs per single crimped hose.
• Ergonomics and safety: The construction of the machines ensures high working comfort for the operator and minimizes the risk of accidental damage to the hose's outer cover, which often occurs when using unprofessional heat sources.

Frequently Asked Questions (FAQ)

Does the thermal sealing device affect the pressure parameters of the hose?
No, this process is an external method of anti-corrosion protection. A correctly performed cover shrinking operation does not affect the structure of the steel braid or the inner layer of the hose, so the strength parameters of the hose remain intact.

Is it necessary to use special covers when working with the device?
Yes, dedicated heat-shrink caps should be used, which exhibit high resistance to oils, greases, and UV radiation after thermal processing. Using covers that do not meet technical standards may result in a rapid loss of sealing properties.

Does the device have temperature regulation?
Yes, the offered devices are equipped with control systems that allow for precise selection of the temperature and process time relative to the wall thickness of the cover, protecting the hose from overheating.
