Made of silicone, its high elasticity and flexibility allow it to fit most holes. The silicone material offers remarkable resistance: it easily withstands high temperatures, resists acids, alkalis, and common chemicals, and does not harden or shrink, even after prolonged use. It features a non-slip surface and good wear resistance, compression resistance, and shock absorption.

The round silicone plug is an essential sealing and protective element.

Its versatility extends from the laboratory, where it effectively seals bottles, flasks, and test tubes, to everyday use in the kitchen, for plugging holes in sinks and pipes, and for protecting threads in furniture making. They also protect sensitive openings in precision instruments and meters, radio motors, and other electronic devices. Instructions: First, clean the mounting hole. Once dry, place the silicone plug into a correspondingly sized hole or sealed pipe to complete the installation. Note: Due to manual measurement, the actual product size may vary slightly by ±1 to 43 mm. Due to differences between production batches, raw material characteristics, and shooting/display equipment, the actual color may vary slightly. Please refer to the actual product received.
