Hose assembly parts, during operation, can reduce the impact of various internal and external operating conditions on rubber hoses, including preventing the rubber hose from whipping when working under high pressure, mitigating hose abrasion in construction sites, mines or quarries and hose corrosion caused by seawater during ship traveling on the sea. Hose assembly parts help to limit the movement range of the hose and extend the lifespan of the hose.
