Whether a protective cover is needed when using food grade silicone tubing outdoors depends on the specific usage scenario. Food grade silicone tubing itself has the advantages of high temperature resistance, corrosion resistance, softness, and easy cleaning, making it suitable for transporting liquids that meet food hygiene requirements. But the outdoor environment is complex and may face challenges such as long-term exposure to ultraviolet radiation, temperature changes, physical wear or chemical corrosion, which may accelerate the aging, cracking or damage of silicone tubes. A protective outer cover can provide a physical barrier to reduce the effects of ultraviolet radiation, wear, or corrosion, while also preventing small animals from biting or accidentally damaging it. In scenarios such as agricultural irrigation and outdoor parts of food processing equipment, the use of an outer cover can significantly extend the lifespan of silicone tubing and reduce maintenance costs. If the outdoor environment is relatively mild, such as short-term temporary use or controllable environment, there may be no need for a cover; But in long-term exposure to harsh conditions, it is recommended to use a cover to improve safety and durability.
