Frequently Asked Questions
What standard does the 4SP hydraulic hose meet?
The hose meets DIN EN 856 4SP standard, which specifies a four-spiral-layer steel wire reinforcement construction for high-pressure hydraulic applications.
What is the maximum working pressure of the 4SP hose?
Working pressure ranges from 5,075 to 6,090 PSI (350–420 bar) depending on inner diameter. Burst pressure is a minimum 4× working pressure as per the standard.
How does 4SP differ from 2SN or 1SN hydraulic hose?
The 4SP uses four spiral layers of high-tensile steel wire, giving it a much higher pressure rating than 2SN (two braid layers) or 1SN (one braid layer). It is designed for severe-duty hydraulic systems where high pressure and impulse cycles are constant.
What applications require a 4SP hydraulic hose?
Typical applications include heavy construction equipment (excavators, cranes, rock breakers), mining machinery, offshore oil equipment, high-pressure hydraulic presses, and industrial robots.
What hydraulic fluids is it compatible with?
Compatible with petroleum-based hydraulic oils, water-glycol fluids, and many synthetic hydraulic fluids. The inner tube material is selected to match the intended fluid; please specify the fluid when ordering.
What is the bend radius compared to lower-pressure hoses?
The 4SP hose has a larger minimum bend radius than 1SN or 2SN hoses due to its stiffer four-spiral construction. This should be accounted for in routing and hose assembly design.
What is the minimum order quantity?
Standard MOQ is 1,000 meters. Custom lengths and pre-assembled hose assemblies are available with appropriate minimum quantities.
