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

• Temperature Range: -55°C to +200°C continuous operation
• Material Compliance: RoHS compliant, REACH compliant, ELV compliant
• Quality Certification: Manufactured under ISO 9001:2015 and IATF 16949:2016 quality management systems
• Automotive Testing: Tested per OEM specifications for compression set, thermal aging, and weathering
• PPAP Support: Full Production Part Approval Process documentation available

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
