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

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
