2 Pole Blue Silicone Connector Seal – Automotive Connector Cavity Seal Manufacturer in India
ARPL manufactures high-quality 2 pole blue silicone connector seals for automotive wiring harness applications requiring high-temperature performance. As a leading automotive connector seal manufacturer in India, we supply connector cavity seals to OEM and Tier-1 wiring harness manufacturers serving global automotive programs. This silicone rubber connector seal provides essential environmental protection for sensitive electrical connections in extreme temperature environments.
The 2 pin silicone connector cavity seal is installed inside female connector housings where it seals around individual wires entering the connector. This design prevents ingress of water, dust, and environmental contaminants that could cause electrical failures. Applications include exhaust gas temperature (EGT) sensor connectors, turbocharger actuator connectors, EGR valve connectors, DPF/SCR sensor connectors, EV battery management systems, motor controllers, and any application where temperatures exceed 120°C.
Silicone Material Properties
This connector seal is manufactured from Silicone Rubber (VMQ), selected specifically for its exceptional temperature resistance and long-term stability. Silicone connector seals are the preferred choice for high-temperature applications where NBR and EPDM materials cannot perform.
- Extreme Temperature Range: Silicone operates continuously from -55°C to +200°C, with intermittent capability to +230°C
- UV and Ozone Resistance: Excellent weathering resistance for exterior and exposed connector applications
- Low Compression Set: Silicone maintains sealing force over extended periods, even under thermal cycling
- Electrical Insulation: Good dielectric properties suitable for high-voltage EV connector applications
- Chemical Resistance: Resistant to water, alcohols, dilute acids, and bases (limited oil resistance)
ARPL also offers alternative materials: NBR for oil/fuel resistance (-40°C to +120°C), EPDM for weather/ozone resistance, HNBR for combined oil resistance and higher temperature, and FKM (Viton) for extreme chemical and temperature resistance.

Frequently Asked Questions
Find answers to common questions about silicone connector seals for high-temperature automotive applications
A 2 pole blue silicone connector seal is a rubber connector cavity seal that fits inside female automotive connector housings to seal around individual wires. Silicone connector seals are specifically chosen for high-temperature applications (-55°C to +200°C) including exhaust gas temperature (EGT) sensors, turbocharger connectors, EGR valve connectors, DPF/SCR sensor connectors, and EV battery/motor connectors where temperatures exceed 120°C.
Silicone connector seals offer wider temperature range (-55°C to +200°C), excellent UV/ozone resistance, and superior low-temperature flexibility—ideal for exhaust systems, EV applications, and exterior connectors. NBR connector seals provide excellent oil and fuel resistance (-40°C to +120°C)—preferred for engine compartment applications with hydrocarbon exposure. ARPL can recommend the optimal material based on your specific environment.
When used in a properly designed connector system with correct wire diameter matching and appropriate connector housing, silicone connector seals can achieve IP67 (dust-tight, protected against temporary immersion) or IP68 (dust-tight, protected against continuous immersion) protection ratings.
Silicone connector seals operate continuously from -55°C to +200°C, with intermittent capability to +230°C. They excel in exhaust system applications (EGT sensors, turbochargers, EGR valves, DPF/SCR systems), EV high-voltage connectors, and exterior applications requiring UV/ozone resistance. Note that silicone has limited oil resistance—for oil-exposed applications, NBR or HNBR is recommended.
Yes, ARPL offers complete custom development capability for silicone connector cavity seals. We can work from customer drawings, reverse-engineer samples, or develop new designs for specific connector families. Our engineering team supports different pole configurations, colours, silicone grades (HCR Silicone, LSR), and hardness options to meet your specific high-temperature sealing requirements.
