Battery Seal Red Silicone Connector Seal

Battery Connector Seal Manufacturer – EV Battery Silicone Connector Seal

ARPL manufactures high-quality battery connector seal and EV battery connector seal products for electric vehicle applications. As a leading battery connector seal manufacturer in India, we supply EV connector seal and high voltage connector seal products to OEM and Tier-1 manufacturers globally. This silicone battery seal provides essential IP67 IP68 waterproof protection for electric vehicle battery systems.

The battery connector seal is installed inside EV battery connector housings where it seals around individual high voltage cables. This waterproof battery connector seal prevents ingress of water, dust, and contaminants critical for battery pack integrity. Applications include EV battery pack connectors, high voltage distribution unit connectors, motor controller connector seal, DC-DC converter connectors, onboard charger connectors, and any high voltage connector seal application.

Silicone Material Options for EV Applications

This EV battery connector seal is available in multiple silicone formulations optimized for high voltage and electric vehicle requirements.

• VMQ Silicone Battery Seal: General purpose silicone, -55°C to +200°C with excellent dielectric properties
• HCR Silicone Battery Seal: High Consistency Rubber for compression/transfer moulding
• LSR Battery Connector Seal: Liquid Silicone Rubber for injection moulding, ideal for high-volume EV production
• Excellent Dielectric Properties: High electrical insulation for high voltage connector applications
• Low Compression Set: Maintains sealing force under thermal cycling in battery environments

All battery connector seal products meet RoHS and REACH compliance requirements for EV applications.

Vehicle Segment Applications

ARPL supplies silicone connector seals to OEMs and Tier-1 wiring harness manufacturers serving diverse vehicle segments with high-temperature requirements:

• Passenger Cars: Exhaust sensors, turbocharger connectors, and underhood high-temperature applications
• Commercial Vehicles: DPF/SCR sensor connectors, exhaust aftertreatment system connectors for trucks and buses
• Electric Vehicles (EV): Battery management system (BMS), motor controller, inverter, and DC fast charging connectors
• Hybrid Electric Vehicles (HEV/PHEV): High-voltage connectors, regenerative braking sensors, and thermal management systems
• Motorcycles: Exhaust sensor connectors, exposed wiring harness applications requiring UV resistance
• Off-Highway Vehicles: Construction and agricultural equipment with high-temperature engine and exhaust applications

High-Temperature Operating Environments

Silicone connector seals excel in environments where extreme temperatures are encountered:

• Exhaust Gas Temperature (EGT) Sensors: Operating at +200°C continuous near exhaust manifold and turbocharger
• Turbocharger Actuator Connectors: Exposed to radiant heat from turbo housing (150°C to 200°C)
• EGR Valve & Cooler Connectors: High exhaust gas temperatures in emissions control systems
• Diesel Particulate Filter (DPF) Sensors: Temperature and pressure sensors in exhaust aftertreatment
• SCR System Connectors: AdBlue/DEF dosing unit and NOx sensor connectors
• Lambda/Oxygen Sensors: Pre-cat and post-cat O2 sensor connectors near exhaust
• EV Motor Controllers: High-voltage connectors in thermally demanding motor and inverter applications
• Exterior Connectors: UV-exposed lighting, antenna, and sensor connectors requiring weathering resistance

Why Choose Silicone Material for Connector Seals?

Silicone Rubber (VMQ) is the preferred elastomer for high-temperature automotive connector seals due to its unique combination of properties:

• Extreme Temperature Range: Operates from -55°C to +200°C continuous, with intermittent capability to +230°C
• UV and Ozone Resistance: Excellent weathering resistance for exterior and exposed applications
• Low Compression Set: Maintains sealing force over extended periods even under thermal cycling
• Excellent Low-Temperature Flexibility: Remains flexible in extreme cold where other materials become brittle
• Electrical Insulation: Good dielectric properties for high-voltage EV applications
• Long Service Life: Resistant to aging, oxidation, and degradation over time
