Connector Seals

Terminal seals are rubber components that seal individual wires entering a connector. They work along with the main connector seal to ensure a complete waterproof multi-pin connector system.

Cavity plugs (sealing plugs) are used to close unused pin positions in a multi-pin connector. This ensures the connector remains fully waterproof even when not all pins are populated.

Yes, custom connector seals, terminal seals, and rubber cavity plugs can be made based on OEM drawings, pin configuration, materials needed, and application environment.

Terminal seals are available for 2P–34P multi-pin connectors, including automotive, EV, and industrial connector systems.

Terminal seals are commonly made from EPDM, HNBR, silicone (VMQ), and FKM, depending on resistance needed against oils, heat, and environmental exposure.

They are used in both automotive and industrial applications such as:

• Control module connectors
• Industrial machine connectors
• Robotics wiring
• EV battery and motor connectors
• Lighting and sensor systems
