01Main advantages:
02Extreme working pressure: withstands very high continuous pressure, from 250 to 420 bar depending on size, significantly exceeding standard braided hoses.
03Four-layer steel reinforcement: equipped with four spiral layers of high-strength steel wire, preventing hose deformation and expansion during sharp pressure spikes.
04Impulse durability: withstands millions of working cycles and pressure shocks, ensuring long service life without damage.
05Outer layer protection: made from special synthetic rubber resistant to ozone, abrasion, oils, and severe climatic conditions.
06Ideal compatibility with fittings: works best with original Cast S.p.A. fittings, preventing fluid leakage even at the most critical points.
07Wide temperature range: maintains flexibility and properties from -40°C to +100°C, with short-term operation up to +125°C.
08Technical data by size:
09Key parameters of standard models, including the popular DN31 series: inner diameter, maximum working pressure, and bend radius.
