Hose O.D. Pressure Rating max. working pressure min. burst pressure min. bend radius weight DN Inch Size mm mm MPa psi MPa psi mm kg • No-Skive hose construction – Compact design • Smaller bend radius and reduced outside diameter • Fire-retardant cover • Railway approved: • European Standard EN 45545 HL2 for R22 (internal) and HL3 for R23 (external) 477RH EliteNo-Skive 2 wire braids and fire-retardant cover Primary Applications For general-medium pressure hydraulic systems and demanding bend radii applications such as lifting equipment. Type Approvals For details please refer to catalogue C-4400/UK, pages Ab-16 to Ab-19 Restrictions Should not be used for high-impulse hydraulic applications to replace spiral construction hoses. Construction Inner Tube: Nitrile (NBR) Reinforcement: Two braided layers of high-tensile steel wire Cover: Fire-retardant synthetic rubber Temperature Range ............ -40 °C up to +100 °C Exception: Air .................................... max. +70 °C Water ............................... max. +85 °C Recommended Fluids Petroleum and water-glycol based fluids, lubricating oils, air and water. For air above 1.7 MPa, the hose cover must be pin-pricked. Consult the chemical compatibility section in catalogue C-4400/UK, pages Ab-24 to Ab-32 for more detailed information. Fitting Series 48 The combination of high temperature and high pressure can reduce the hose life. Railway 477RH Parkrimp No-Skive Hose Medium Pressure up to 45.0 MPa Hose layline example
