Question 2: What happens to the working pressure at a higher temperature?

Answer 2: As temperature goes up, hose/tube gets soften, leading to lower working pressure. Each product has technical data regarding “Relationship between Working Temperature and Maximum Working Pressure.” Please check this data for each product.

Question 3: How do we cut hose/tube?

Answer 3: You can cut a tube with a tube-cutter. For a hose, you can cut with a knife or a hose cutter. To cut a spring hose, make sure to cut the spring wire off neatly with a nipper.

Question 4: In what ways do we dispose of hose/tube?

Answer 4: In case of disposing, please follow the local governmental regulations.

Question 5: What is the difference between burst pressure and working pressure?

Answer 5: Burst pressure is the value of pressure when hose gets burst after adding pressure to the hose. Usually, a yarn-casting off or pinhole bursting occurs when hoses get burst. Burst pressure is usually as four times as working pressure. Also, depending on the temperature, working and burst pressure might change.

Question 6: Why does the hose change the color into white if the hot water is transferred to the transparent PVC hose?

Answer 6: By pouring the hot water into the hose, the part of water molecule goes into the PVC hose. This is called moisture absorption. The hose looks like white if the water molecule goes into the PVC resin hose due to the fact that a refraction angle changes. If the hose turns white, there …
