Custom NBR Connector Seal

Custom NBR Connector Seal Manufacturer – Oil Resistant Automotive Connector Seal

ARPL manufactures high-quality custom NBR connector seal products for automotive wiring harness applications. As a leading NBR connector seal manufacturer in India, we supply custom nitrile rubber connector seal and oil resistant connector seal products to OEM and Tier-1 manufacturers globally. This custom NBR connector seal provides essential IP67 IP68 waterproof protection.

The custom NBR connector seal is installed inside connector housings where it seals around individual wires. This waterproof NBR connector seal prevents ingress of water, oil, fuel, and contaminants. Applications include engine bay connector seal, fuel injector connector seal, transmission connector seal, oil pressure sensor connectors, fuel pump connectors, and any application where connectors are exposed to hydrocarbons.

NBR Material Properties – Oil & Fuel Resistance

This custom NBR connector seal is manufactured from nitrile butadiene rubber for superior oil and fuel resistance.

• Oil Resistant Connector Seal: Excellent resistance to petroleum-based oils, fuels, and greases
• Fuel Resistant Connector Seal: Withstands gasoline, diesel, and biodiesel exposure
• Temperature Range -40°C to +120°C: Suitable for engine bay and underhood applications
• Hydrocarbon Resistance: Ideal for fuel system and transmission connector applications
• Low Compression Set: Maintains sealing force under operating conditions

All custom NBR connector seal products meet RoHS and REACH compliance requirements for automotive 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

• 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
