High-pressure hose GOST 6286-73 is an analogue of foreign hoses according to specifications EN 853 1ST (SAE 100 R1A, ISO 1436-1, 1ST/R1A) and EN 853 2ST (SAE 100 R2A, ISO 1436-1, 2ST/R2A).
Hoses manufactured in accordance with GOST 6286-73 or DIN EN 853 standard are used as flexible pipelines in hydraulic systems of agricultural machines, hydraulic drives of construction, road and municipal machines for high-pressure supply of hydraulic fluids according to ISO 6743, gasoline, kerosene, oil-based oils, oil and water emulsions, emulsion, soluble and mineral oils in the temperature range from -40°C to +100°C; liquids containing water in the temperature range from -40°C to +70°C; +70°C.
Hose groups: A, B, V, Z.
A group - with the use of a wire with a breaking force not less than 15,0 kg.
B group – with the use of wire with a breaking force not less than 17.5 kg.
Z, V groups – wire brass plated surface with a breaking force not less than 20.0 kg.
Safety margin of tensile strength by hydraulic pressure: 3Р – for hoses of groups А and B ;4Р – for hoses of group Z.
