A hydraulic hose consists of an inner tube through which the fluid is conveyed and comes into direct contact with the hydraulic fluid. The rubber or other synthetic material used for this needs to be compatible and able to withstand the range of working temperature without losing its chemical and physical stability.
The hydraulic hoses can be made using a variety of materials, depending
on the factors of oil compatibility, abrasion resistance etc. These
Plastic - The plastic materials comprise of:
Nylon, Braided nylon hose , Polyvinyl chloride, Textile braided
hoses, Thermoplasts, Teflon, Chloro sulfonated polyethylene (Hypalon),
Ethylene propylene diene (EPDM), Chlorinated polyethylene etc.
Homogeneous Synthetic Rubber - This category
includes hose materials like: Buna N, Neoprene, Natural rubber, Butyl
The hydraulic hose is an important element in the system that needs to
be checked for its reliability and durability during the manufacture
process. In many hydraulic systems, it is necessary to move the drive
unit along with the oil lines. Here, synthetic-rubber is suited as the
material for the hydraulic hoses. Plastic tubings are also used in
hydraulic systems to convey the fluid.
