The Tiema Hose Protection Sleeve is the culmination of decades of experience in the Hydraulic Hose and hose fittings industry. Ourhydraulic hose protector are designed to meet the most stringent of international safety standards, whilst also actively preventing rubber hose damage and potential injury.during the construction process, the hydraulic pipe without the protective sleeve is hit and bursts or the pressure of the hose itself bursts due to excessive pressure. The hydraulic oil in the pipe may leak and cause the machine to be contaminated. On the one hand, the hydraulic hose sleeve can prevent the hose from being injured. And spiral guard can also prevent the hydraulic oil from splashing around after the hose itself bursts. Hydraulic Hose guard Key Feature: • High abrasion resistance • High flexibility • Resistant to water, oils, fuels and hydraulic fluids • Easy to install, no clamps needed • High ozone and external agents resistance.
