The 2 Pole Blue Silicone Connector Seal is a precision-moulded connector cavity seal designed to sit inside female automotive connector housings. This terminal seal creates a reliable environmental barrier around each wire entry point, preventing water, dust, and other contaminants from entering the electrical system. When properly installed in a compatible connector housing, it supports IP67 and IP68 waterproof performance for demanding high-temperature automotive applications.
Manufactured from premium Silicone Rubber (VMQ), this connector seal offers an exceptional operating temperature range from -55°C to +200°C—making it the ideal choice for exhaust system sensors, turbocharger connectors, EGR valve connectors, and EV battery/motor applications where extreme temperatures are encountered. The excellent compression set resistance ensures long-term sealing performance even under thermal cycling conditions.
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.
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.
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.
With over 30 years of rubber moulding experience, ARPL delivers manufacturing excellence in precision sealing components including high-precision tooling, flash control with cryogenic deflashing, zero-defect quality systems, and full PPAP support. ISO 9001:2015 and IATF 16949:2016 certified, we support customers in Germany, USA, Mexico, Turkey, Brazil, UK, UAE, Thailand, Vietnam, Poland, Czech Republic, and Hungary.

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.
