Hydraulic hose configurator

The overall length of a hose assembly is always measured from sealing head to sealing head for straight fittings. For 90° or 45° elbow fittings, it is measured to the center of the sealing face. During installation, make sure to choose a hose length that prevents tensile stress and excessively tight bending radii under pressure.

The main differences lie in pressure rating and flexibility:

• 1SN: Single wire braid layer (for medium pressures).
• 2SN: Double wire braid layers (for higher operating pressures).
• 2SC: Compact hose with two wire braids – allows tighter bending radii in confined spaces.
• 4SP: Four spiral steel wire layers for extremely high pressures and heavy pressure surges.

Pay attention to the thread type and sealing surface:

• Metric (DKL/DKS): European standard with thread dimensions in millimeters (e.g., M12x1.5).
• BSP (inch): Whitworth thread, commonly referred to as G 1/4" or G 1/2" (60° cone angle).
• JIC / UN/UNF: US standard with a characteristic 37° flare cone.
• ORFS: Flat-face UNF thread with O-ring seal.
• SAE Flange (3000/6000 psi): For very high pressures and high flow rates.

This depends on the ports of your power units, pumps, or cylinders. If the hose fitting does not connect directly to your component, you can find a wide selection of suitable male stud fittings, reducers, elbow fittings, and T-connectors in metric, BSP, NPT, and JIC configurations in our Hydraulic Fittings category.

The displacement angle is essential when both ends of the hose assembly feature elbow fittings (e.g., 45° or 90°): Look along the hose axis. Align the rear fitting vertically pointing upwards (12 o'clock position). The displacement angle is the degree angle (0°–360°) measured clockwise to the front fitting.

Protective sleeves extend service life and increase occupational safety:

• POWERTEX / TEX: Provide excellent mechanical abrasion protection against friction on edges or machinery parts.
• SKW: Offers additional protection against heat impacts and guards operating personnel against fluid bursts.

According to safety standards (e.g., DGUV Rule 113-020), hydraulic hose assemblies should generally be replaced after a maximum of 6 years (including a max. storage period of 2 years). With the LöSi reminder service and our hose tagging system, you will be notified automatically before inspection or replacement intervals expire.
