4 SP - HYDRAULIC SPIRAL HOSE WITH FOUR COILS
| 4 SP
|
Four-coiled (spiral) sleeve, corresponds DIN EN856, designed for hydraulic systems using hydraulic fluids based on mineral and synthetic oils(HL, HLP, HLPD, HVLP),
emulsions based on mineral oils (HFAE, HFAS, HFB), liquids based on glycols (HFC), lubricants based on vegetable and mineral oils, cooling water and compressed air
Not suitable for hydraulic fluids based on phosphate ester (HFD)
Conditionally suitable for biodegradable hydraulic fluids (HETG, HEPG, HEES).
In case of use of the sleeve for other purposes, it is necessary to consult with the manufacturer
