Hoses & Fittings
In the Hydraulic Connection Technology section at LöSi®, you will find a comprehensive range of connecting elements – such as screw connections, adapters, hydraulic hoses and pipes, quick couplings and fittings – which are essential for a safe, powerful and durable hydraulic system. Hydraulic connection technology forms the link between pumps, motors, cylinders and power units and ensures that forces are transmitted reliably – without leaks, pressure losses or failures. By choosing high-quality connection solutions, you can ensure that your hydraulic system will function reliably for many hours of operation.
What is Hydraulic Connection Technology?
Hydraulic connection technology is the "nervous system" of every hydraulic system. It encompasses all components necessary to conduct oil flows safely, leak-free, and with stable pressure between pump, valve, and actuator.
Our range covers the entire chain of fluid technology. From high-pressure resistant hydraulic hoses that compensate for movements, to rigid hydraulic pipes for durable fixed installations, to the decisive interfaces: fittings, ball valves, and couplings. The goal is always a seamless connection that withstands vibrations, pressure peaks, and environmental influences.
Benefits of Our Connection Technology Components
A chain is only as strong as its weakest link. Inferior connections are the main cause of leaks and expensive downtime. Our components are designed for precision and durability.
Benefit from technical excellence:
- Tightness & Safety: High-quality fittings and valves prevent oil leakage and pressure loss – even under extreme load changes.
- Flexibility: With our hydraulic hose configurator, you can create custom hose assemblies to measure.
- Efficiency: Flow-optimized couplings and ball valves minimize resistance and increase the efficiency of the system.
- Quick Maintenance: Push-in and screw couplings enable quick changing of attachments without oil loss.
Typical Areas of Application for Connection Technology in Hydraulics
Every application places different demands on the connection. While rigid pipes in industrial plants last for decades, hoses in construction machinery must follow permanent movements:
- Mobile Machinery: Flexible hoses and robust fittings for excavators and agricultural machinery.
- Stationary Mechanical Engineering: Piping of presses and power units with durable hydraulic pipes (UV and weather resistant).
- Agricultural & Forestry Technology: Use of breakaway couplings and ball valves to control attachments.
- Offshore & Heavy Duty: Corrosion-resistant solutions for extreme environments.
Selection Criteria & Technical Data of Connection Elements
The variety of threads and standards is huge. To maintain the integrity of your system, correct selection is crucial.
Pay attention to these points when assembling:
- Pressure Range (Nominal Pressure): Are hose, pipe, and fitting designed for the maximum system pressure?
- Connection Type: Do you need metric threads, BSP (inch), JIC, or ORFS for the sealing surfaces?
- Material & Environment: Galvanized steel for standard applications or stainless steel for
