Automotive Connector Seals - Industrial
ARPL manufactures industrial automotive connector seals designed for harsh operating environments, including heavy-duty vehicles, construction equipment, mining machinery, agricultural equipment, and off-highway automotive applications. These connector seals are engineered to resist oil, grease, dust, vibration, temperature extremes, and continuous mechanical stress.
Available Connector Seal Materials
We manufacture connector seals, single wire seals, and cavity plugs in all materials including self-lubricating (oil bleeding) silicone and LSR connector seals, with custom hardness options tailored to your application requirements.
About ARPL Connector Seals (Single Wire Seals / SWS)
ARPL is a leading connector seal manufacturer and rubber seal manufacturer in India with over 30 years of experience in precision rubber moulding for automotive applications. As a trusted connector seal supplier and automotive seal exporter, our single wire seals (SWS), cavity seals, terminal seals, and interfacial seals are designed to provide reliable waterproof sealing for automotive wiring harness connectors, protecting electrical connections from water, dust, oil, and environmental contaminants.
Our wire seal connector products feature three-lip and multi-lip seal configurations for redundant sealing, with precise dimensional control ensuring perfect fit inside connector housings and reliable sealing around wires of various gauges. We manufacture connector seals, cavity plugs (dummy plugs/blind plugs), mat seals (family seals), interfacial seals, cable seals, and grommet seals in configurations from 2-pole to 36+ pole, supporting a wide range of automotive sealed connector systems used by major OEMs globally.
With advanced manufacturing capabilities including compression moulding, transfer moulding, and injection moulding for LSR connector seals, we produce connector seals with excellent flash control using cryogenic deflashing technology. Our connector seals meet international automotive standards including IP67/IP68/IP6K9K protection ratings and are compliant with USCAR-2, LV214, and OEM-specific requirements. Our harness automation ready seals are designed for high-speed automated wire insertion processes.
Single Wire Seal vs Cavity Plug (Dummy Plug) vs Mat Seal
Single wire seals (SWS) (also called connector seals, cavity seals or terminal seals) fit inside connector housings to seal around individual wires using three-lip configuration. Cavity plugs (also known as dummy plugs, dummy seals, or blind plugs) are solid plugs that seal unused connector cavities where no wire is present, acting as environmental seals and contaminant barriers. Mat seals (family seals/interfacial seals) are larger sealing components that seal multiple wires simultaneously at the connector interface. ARPL is a complete rubber seal supplier India manufacturing all types of wiring harness seal components including self-lubricating (oil bleeding) seals for enhanced wire insertion in sensor connector seals, ECU connector seals, headlight connector seals, and high voltage connector seals for EV applications.

Frequently Asked Questions
Find answers to common questions about connector seals for automotive applications
A connector seal (also called single wire seal, terminal seal, or cavity seal) is a precision-moulded rubber component that fits inside automotive connector housings to provide waterproof sealing around individual wires. Connector seals prevent water, dust, and contaminants from entering the connector cavity, achieving IP67/IP68 environmental protection for wiring harness applications.
Single wire seals (connector seals) seal around individual wires inside connector cavities. Cavity plugs (dummy seals) are solid rubber plugs that seal unused connector cavities where no wire is present. Mat seals (family seals) are larger sealing components that seal multiple wires simultaneously at the connector interface. ARPL manufactures all types as a complete wiring harness seal supplier.
ARPL manufactures connector seals from silicone (VMQ/HCR/LSR) for high temperature applications (-55°C to +200°C), NBR for oil and fuel resistance (-40°C to +120°C), EPDM for weather resistance, and FKM connector seals (Viton) for extreme chemical and temperature exposure. We also offer self-lubricating (oil bleeding seal) grades for enhanced wire insertion.
