The hydraulic hose standard is a gauge on which parties to the transaction make deals based, and hydraulic hose specifications are stipulated on the standards, so dealers can confirm what hydraulic hoses they are ready to transact. EN standard hydraulic hose is one of the main types.
EN standard hydraulic hose
EN is the abbreviation of European Norm, the EN standard hydraulic hose originates from DIN (Germany Standard), hydraulic hoses which conform to EN standards are printed with the standards code on the outer surface as a part of the brand lay line.
Like SAE hydraulic hoses, EN hydraulic hoses have the same fundamental construction with three plies from the perspective of the section, besides, they have similar or identical requirements to their members.
EN 853 1SN, EN853 2SN, EN 857 1SC, EN 857 2SC, EN 856 4SP, and EN 856 4SH hydraulic hoses are typical instances to prove the description above.
EN 853 1SN hydraulic hose
EN 853 1SN hydraulic hoses are single steel wire braided reinforced hydraulic hoses, they have the same requirement as SAE 100R1 hydraulic hose, the maximum working pressure is 3625psi with the inner diameter of 3/16″ and the minimum working pressure is 580psi with the inner diameter of 2″, the working pressure range from 580psi to 3625psi in accordance with the inner diameter range from 3/16″ to 2″, but in adverse proportion.
EN 853 2SN hydraulic hose
EN 853 2SN hydraulic hoses are double steel wire braided reinforced hydraulic hoses, and they have the same requirement as SAE 100R2 hydraulic hoses, identically, the maximum working pressure is 6018psi with the inner diameter of 3/16″, and the minimum working pressure is 1160psi with the inner diameter of 2″, the working pressure spectrum range from 1000psi to 6000psi approximately.
EN 857 1SC hydraulic hose
EN 857 1SC hydraulic hoses are the compact counterparts of EN 853 1SN hydraulic hoses, compact hydraulic hose means they have a smaller outer diameter and bend radius, when they are laid out at some bend, they save length. but when comparing the EN 853 1SN, EN 857 1SC hydraulic hoses have narrow spectrum for option.
EN 857 2SC hydraulic hose
EN 857 2SC hydraulic hoses are the compact counterparts of EN 853 2SN hydraulic hoses, the former ones have a smaller outer diameter and bend radius than the latter ones. The working pressure range from 2400 psi to 5800 psi in the inner diameter spectrum between 1/4″ to 1″ but in adverse proportion.
EN 856 4SP hydraulic hose
EN 856 4SP hydraulic hoses are four plies of spiral wound steel wire hydraulic hoses, and they also conform to ISO 3682 4SP criteria. Spiral wound steel wire construction increases the pressure resistance for hydraulic hoses, they are much stiffer and less flexible than the braided ones, but they are suitable for high-impulse and heavy-duty applications thus the braided ones are not competent.
EN 856 4SH hydraulic hose
EN 856 4SH hydraulic hoses are also four plies of spiral wound steel wire hydraulic hoses, and they also adhere to ISO 3682 4SH criteria. The construction is identical to EN 856 4SP, but they have fewer options in their diameter range. however, each spec hydraulic hose has more W.P. than EN 856 4SP counterpart.
In European Norms, commonly used hydraulic hoses are stipulated with the corresponding number, such as 853, 856, or 857, these standards extremely facilitate communication between buyers and sellers, when you order the hydraulic hoses, look up the hydraulic hose specification chart above to find the right one, if you have special requirement, we can find the corresponding number in the EN which above your requirements, thus, EN criteria has become our mutual gauge based on, especially in European countries.
EN 853 and EN857 hydraulic hoses are braided hydraulic hoses, they are widely used in low- or medium-pressure applications, such as pressure washer machines, agriculture machines, and mine stationary support systems, etc.
EN 856 4SP and 4SH hydraulic hoses are spiral wound hydraulic hoses, they often find their applications in heavy-duty and high-impulse machines such as earth movers, dump trucks, excavators, loaders, and so on.
