Silicone rubber plugs

Silicone rubber plugs and tapered plugs are able to resist high temperatures and exposure to aggressive conditions over longer periods due to their perfect thermal resistance and electrical insulation. Silicone rubber plugs are used to cover powder coating, E-coating, wet painting, plating, and anodizing. Silicone rubber plugs may be produced by compression molding or injection molding. Usually, the plug that is impermeable to water is produced of silicone or rubber. One of the benefits is that the product is affordable. Then the second is that the silicone rubber plug has an excellent shaping ability when compared to other materials during the process of closing the hole. In the third place, their resistance to outdoor elements as well as their resistance to durability features compared to plastic have better results. When the surrounding environment is specific, no matter if it is oil or chemicals you should select rubber for making silicone plugs. Silicone rubber plugs can be found in a diverse range of applications.

These silicone rubber plugs work extremely well when filling holes in numerous objects. Most commonly, the silicone rubber plugs come in use to seal components, particularly the ones that contain aggressive chemicals and high temperatures. As a result, the rubber caps and silicone rubber plugs have been designed for applications, which require heat and chemical resistance. In addition, they are widely offered in different forms and dimensions, as well as rubber hole plugs can also be made according to your dimensions in order to fit where they are required. These rubber plugs are perfect for masking or sealing components involved in high-temperature powder coating processes, plus in medical applications that require sterilization. Silicone rubber plugs are manufactured using various types of rubber. Most commonly, several types of synthetic rubber including silicone and vinyl are used in the production of these rubber caps.

Stopper & Plug Size Catalog

Compare four stopper profiles and check the selected part dimensions against your opening and available depth. Each profile has its own drawing and dimension meanings.

Custom colors are available to your Pantone color code. Include the code in your inquiry.
