Quick Answer: Which Alfagomma Hydraulic Hose Should You Choose?
Alfagomma 2SN is a common choice for suitable general hydraulic applications. 4SP and 4SH are four-spiral reinforced hose types for demanding high-pressure duties. R17 Compact is worth considering where compact routing is important, while AT5K Flexextreme may be an option for demanding applications requiring its particular performance characteristics.
Important: No hose should be selected by application category alone. The correct assembly must meet the machinery manufacturer’s requirements for working pressure, hose diameter, fittings, fluid compatibility, temperature, bend radius and routing.

7 Things to Check Before Choosing a Hydraulic Hose
Selecting the correct hydraulic hose involves more than choosing a familiar product name.
1. Working Pressure
The hose assembly must be suitable for the hydraulic system’s operating pressure and relevant pressure transients. The pressure rating of the complete assembly matters, not just the hose itself.
2. Internal Diameter
Hose internal diameter affects fluid velocity and pressure losses. The correct size should follow the system design and machinery manufacturer’s requirements.
3. Hydraulic Fluid Compatibility
Confirm that the selected hose is compatible with the fluid being conveyed, including any special hydraulic fluids.
4. Operating Temperature
Both fluid temperature and surrounding environmental conditions must fall within the manufacturer’s specified limits.
5. Bend Radius and Installation Space
Hoses must not be bent more tightly than their specified minimum bend radius. Compact hose designs may offer installation advantages, but suitability must be confirmed.
6. Fittings and Connections
End fittings must match the equipment connections and be approved for use with the selected hose and assembly system.
7. Abrasion, Movement and Environmental Exposure
Consider whether the hose will experience rubbing, vibration, movement, external heat or other damaging conditions.

Replacing an Existing Hose or Selecting One for New Machinery?
Replacing a Failed Hydraulic Hose
Start with the original hose specification and machinery requirements.
- Check the hose layline.
- Identify the internal diameter.
- Confirm the original hose type.
- Identify both end fittings.
- Measure the assembly correctly.
- Check the cause of failure.
Never assume a different hose type is interchangeable without confirming suitability.
Selecting Hose for a New Installation
Selection should be based on the hydraulic system design and operating conditions.
- Determine required working pressure.
- Calculate appropriate hose size.
- Confirm fluid compatibility.
- Assess movement and routing.
- Check temperature and environment.
- Select approved fittings and assembly components.
Technical selection should be confirmed before assembly or installation.
What Information Do We Need to Supply the Correct Hose?
Providing a few details can help our team identify the required assembly more efficiently.
- Hose markings: The existing layline or manufacturer part number, if readable.
- Hose size: Internal diameter or nominal size.
- Fitting details: Connection type, size and orientation.
- Assembly length: The required finished hose assembly length.
- Machinery details: Make, model and hydraulic application.
- Operating conditions: Pressure, heat, movement, abrasion or restricted routing.
- Service requirement: Trade counter supply or mobile replacement.
Tip: Photographs of the hose markings, fittings and installation can help with initial identification, although measurements and specifications may still need to be confirmed.
Not Sure Which Hydraulic Oil You Need?

Hydraulic Hose Selection & Safety
Incorrect hose selection or installation can create serious safety hazards.
- Never exceed the specified working pressure of a hose assembly.
- Never use your hands to search for hydraulic leaks.
- Do not mix incompatible hose fittings or ferrules.
- Never patch a damaged hydraulic pressure hose.
- Follow manufacturer isolation and depressurisation procedures.
- Account for stored hydraulic energy and unsupported loads.
- Use correctly specified and assembled replacement components.
Suspected hydraulic fluid injection injuries require urgent medical attention, even when the visible wound appears minor.
