The basic hydraulic hose construction involves three layers. These layers help maintain a consistent and reliable flow of liquid while protecting the overall assembly from breaking down as a result of wear or abrasion.
Inner tube: The inner tube is designed to be compatible with the liquid it carries, allowing both free-flowing elasticity and pressure-resistant stress bearing. This tube is often made from PDFE (PTFE), thermoplastic, or synthetic rubbers.
Reinforcement layer: This layer surrounds the inner tube and is composed of a coiled or braided wire. This set up supports the tubing while protecting against tears.
Outer layer: This layer is made of rigid materials and is designed to protect the innards of the hose.
