Waterproof Single Wire Seal Blue GM681372 is used for sealing wiring holes: the wire goes through the middle, and multiple circular sealing ribs on the product body press against the connector holes to keep out water and dust. Guoming Rubber & Plastic has been specializing in rubber and plastic seals for nearly twenty years. We can produce both through holes and blind plugs, and we also support custom designs according to drawings. If you're unsure about the working conditions, sending a sample for testing is the most straightforward way.
