Black Silicone Wire Harness Seal

The Black Silicone Wire Harness Seal is a thin-wall sleeve, so it stays flexible and is easy to press onto the connector. The silicone grips the connector housing tightly, and once in place it seals out water, dust and vibration. In a vehicle, it does its job in several places at once: it protects the harness connectors in the engine bay, keeps moisture out of the electrical system, and helps connectors last longer.

Product Parameter (Specification)

Application Scenarios The Black Silicone Wire Harness Seal is widely used in automotive wiring harness systems — engine compartment connectors, sensor connectors, ABS and ECU connectors, and headlamp /taillight harness joints. It keeps water, dust and oil away from terminals, reducing the risk of poor contact and short circuit caused by corrosion.

Quality Control Every batch of seals is produced under the IATF16949 quality management system. Raw material incoming inspection, dimensional measurement, hardness test and 100% visual inspection are carried out before packing, ensuring stable consistency for mass production.

Packaging and Delivery Each seal goes into an inner bag first, then into export cartons — so it arrives clean and undamaged. For large orders, bulk packing is also available to keep your handling cost down.Rolling stock keeps lead time short — we can schedule production according to your monthly demand forecast.
