Because of the high pressure in the sales market Sandblasting hose The raw materials of spare parts are different, and the quality is good and bad. It is difficult for customers to distinguish the quality of spare parts from their appearance. So how to distinguish the advantages and disadvantages of high-pressure sand blasting hose connector?

1. The application of maintenance cannot be ignored

The long-term application of high-pressure sand blasting hose connectors at home is generally not easy to cause concern, but too much application and poor maintenance also buried the potential safety hazard of connector cracking to a certain extent. According to statistics, the service life of connector is 200000 times generally, and it should be replaced after long-term application. When applying the side, you should turn it off and on as gently as possible without turning it repeatedly Plastic hose The knob of the RF connector.

2. Distinguished quality can be collected according to the direct evidence of specifications.

According to statistics, it is still difficult to determine the cause of the crack at the joint. At this stage, the Bureau of Technical and Quality Supervision has released the strongly recommended standards for sealed faucets and the standards for plastic hoses. These two specifications and models adjust the overall objectives of the quality specifications and models of connectors and plastic hoses. Customers can go to the quality inspection department to check the torsional compressive strength of the connecting plastic hose, the tightness of the connecting valve core and the compressive strength of the connecting raw materials. If the content of specifications and standards cannot be achieved, it will be attributed to product quality problems, which can serve as a powerful basis for description.

3. The appearance of plastic hose RF connector is difficult to distinguish between advantages and disadvantages.

Even in pursuit of profitability and cost control, many manufacturers currently choose preferred pig iron (easy to rust) and zinc alloy materials (non corrosion resistant) as raw materials to manufacture high-pressure sand blasting hose connectors, which leads to product quality problems.
