Hydraulic hoses are an essential component in many industrial applications that require the transfer of fluids or gases. High pressure hydraulic hoses are used to transport high-pressure fluids such as water, oil, or hydraulic fluid. One of the most common types of high pressure hydraulic hoses is the Hydraulic hose 4SH.
The Hydraulic hose 4SH is a high-pressure hydraulic hose that is designed to operate in extreme temperatures and harsh environments. The 4SH stands for four layers of reinforcement, which give the hose its strength and durability. The innermost layer of the hose is made of synthetic rubber, which provides a smooth surface for the fluid to flow through. The second layer is made of steel wire, which provides the hose with its strength and flexibility. The third layer is also made of steel wire, but it is wound in the opposite direction to the second layer, which provides additional strength and resistance to deformation. The fourth and final layer is an outer layer of synthetic rubber that protects the hose from external damage and corrosion.
The Hydraulic hose 4SH has a working pressure of up to 6,095 psi and a temperature range of -40°C to +121°C (-40°F to +250°F). It is compatible with a wide range of hydraulic fluids, including mineral oil, synthetic oil, and biodegradable hydraulic fluids. The hose is available in a range of sizes, from 3/8″ to 2″, and is designed to be used with a variety of hydraulic fittings and connectors.
The term “4SH” refers to a specific type of hydraulic spiral hose. In the context of hydraulic hoses, “4SH” stands for a four-spiral wire reinforcement design, providing enhanced strength and resistance to high-pressure conditions. Let’s explore the characteristics, construction, applications, and advantages of hydraulic spiral hoses with a 4SH designation
Characteristics of Hydraulic Hose - 4SH
