G4SP (EN 856 4SP) Hydraulic Hose


EN 856 4SP hose is a high-pressure hydraulic hose with four-wire spiral reinforcement designed to handle extreme conditions and provide reliable performance in heavy machinery applications.

The inner layer of the EN 856 4SP hose is made of oil-resistant synthetic rubber, and four layers of high-strength steel wire are wrapped around the inner layer, with a protective layer of oil-resistant, weather-resistant, and abrasion.

The outer cover of the EN 856 4SP hose is made of oil, weather, and abrasion-resistant synthetic rubber, which protects the hose from external damage and maintains its flexibility in extreme conditions. This hose is capable of handling working pressures of up to 6000 psi (or 400 bar) and a temperature range of -40°C to +100°C (-40°F to +212°F).

EN 856 4SP hoses are typically used in high-pressure hydraulic systems of heavy machinery, such as construction equipment, mining equipment, and industrial machinery.
