English model guidance is provided below. Confirm the exact hose version, operating limits and complete end-fitting arrangement when requesting a quotation.
Steel-Spiral-Reinforced PVC Hose
Flexible Oil and Fuel Hose
Braided Clear PVC Hose
Clear Unreinforced PVC Hose
A smooth, transparent PVC hose without braid reinforcement, used for equipment connections and fluid transfer where the selected material and operating limits are suitable. Transparency allows visual observation of the contents.
Specify inside and outside diameter, length, fluid, temperature and required pressure or vacuum. Wall thickness or transparency alone does not establish pressure, compressed-air or food-contact suitability. The existing reference lists inside/outside diameter pairs from 4/6 mm to 50/58 mm; confirm the requested pair and supplied version.

Reference values for the documented version. Confirm the supplied hose and complete assembly; dimensions alone do not establish a pressure rating.
Steel-Spiral-Reinforced PVC Hose
Transparent PVC hose with embedded steel spiral reinforcement. Selection for transfer or suction duty depends on the actual model's pressure, vacuum, temperature and bend-radius data.
The Armovin reference includes nominal 1/2 to 2 inch sizes, with a separate larger-diameter AR-series table. For the documented 2 inch version, the listed ID is 51.7 mm, OD 61 mm, bend radius 127 mm and pack length 30 m. These values apply to that reference version; confirm the exact supplied hose, end fittings and clamp sizes.
Armovin reference – nominal 1/2 to 2 inches

Reference values for the documented version. Confirm the supplied hose and complete assembly; dimensions alone do not establish a pressure rating.
Flexible Oil and Fuel Hose
Flexible hose selected for the specified oil or fuel composition, including additives. The existing reference describes a smooth-bore, galvanized-wire-reinforced version for compatible lubricating oils and fuels.
Identify the exact fluid, temperature, discharge or suction duty, diameter, length and fittings. For the documented version, the reference table gives ID / working pressure at 20°C / bend radius as: 13 mm / 10 bar / 50 mm; 16 / 10 / 60; 19 / 9 / 70; 25 / 8.5 / 100; 32 / 8 / 130; and 38 / 8 / 150. Confirm model compatibility and temperature derating; these pressures do not apply automatically to other versions.
Reference version – pressure at 20°C
| ID (mm) | Working pressure at 20 C (bar) | Bend radius (mm) |
|---|---|---|
| 13 | 10 | 50 |
| 16 | 10 | 60 |

Reference values for the documented version. Confirm the supplied hose and complete assembly; dimensions alone do not establish a pressure rating.
Braided Clear PVC Hose
Transparent flexible PVC hose with polyester braid reinforcement, identified in the existing range as Technoflex. Standard and heavy versions have different outside diameters.
Select by the actual ID and OD rather than nominal size alone. For example, the documented 1/2 inch standard version is 12.7 mm ID × 19 mm OD; the heavy version is 12.7 × 20.7 mm. The term heavy does not define a pressure rating. Confirm fluid compatibility, pressure, temperature and end retention for the selected assembly.
