Vacuum Glass Suction Cup Key Features to Consider
When choosing a vacuum suction cup, pay attention to these features to ensure safety and suitability for your task:
Load Capacity: Always check the safe working load, which is often specified differently for horizontal and vertical lifts . Never exceed this limit.
Safety Indicators: A "red warning line" on the pump is a crucial safety feature. The line disappearing indicates a secure vacuum is formed. If it reappears during use, it signals a loss of suction, and you should immediately lower the load .
Handle Design: Handles made of ABS plastic, aluminum, or steel provide a comfortable and non-slip grip for better control during lifting .
Material and Seal: The suction cup is typically made of durable rubber like NBR. Features like a triple-seal rim or a ripple pad improve the seal and grip on the surface .
Portability: Many models come with a protective carrying case to store and transport the tool safely, protecting the rubber seal from damage
