The hose coupling has precise effect resistance, and its material generally has a positive elasticity, that can soak up effect energy and step by step release it, efficiently reducing the impact on the hose coupling. In addition, the structural design of the hose coupling can also improve its effect resistance. The spring shape inside the joint and the metal jacket at the out of doors can provide additional protection for the joint, making it much less prone to damage under effect. It must be stated that hose couplings made of various materials and strategies have unique impact resistance. Therefore, in sensible use, it's far vital to pick out suitable hose couplings primarily based on specific working environments and necessities, and behavior regular inspections and protection to ensure their normal operation and lengthy-term use.
