Rubber suction nozzle silicone colorful suction cup

A Rubber suction nozzle combines a contact lip with a passage connected to the suction arrangement. The lip needs to meet the target surface, while the passage must remain clear for the intended airflow. A correctly shaped contact face can still perform poorly if the nozzle is distorted at its connection or obstructed internally.

ETOL can customize the rubber geometry, dimensions and color for the mating connection and handled surface. Compare the target area's curvature and finish with the lip profile. Include the approach angle, since a nozzle presented at an angle may contact on one side before the remainder of the lip can seat.

Fit the connection without collapsing the passage or twisting the body. Inspect the lip for residue and small cuts before evaluating the nozzle in the complete system. Suction performance depends on the available vacuum, leakage, surface condition and operating motion; cup color and size do not establish a handling capacity. During cleaning, clear deposits using a compatible method that does not score the lip or push debris farther into the passage.
