967067-2

The 967067-2 is a Single Wire Seal (SWS) from TE Connectivity’s MQS (Micro Quadlock System) automotive connector series. Designed to provide environmental sealing at the wire entry point of sealed automotive connectors, this elastomeric seal fits around the wire insulation and seats in the seal cavity of the connector housing, preventing moisture, dust, and other contaminants from traveling along the wire and into the connector interior. The 967067-2 is specified for wire cross-sections of 0.50-0.75mm² and fits into connector cavities with a 3.45mm diameter seal cavity. The -2 suffix indicates yellow color, which serves as visual identification of the seal size/wire range. Made from high-quality elastomeric rubber compound that meets SAE J200 automotive standards, these seals maintain their sealing properties across the full -40°C to +130°C operating temperature range. The seals are installed by sliding them onto the wire insulation before the terminal contact is crimped on, and they seat into the rear cavity of the connector housing when the terminal is inserted. Single wire seals are critical components in sealed connector systems, working together with the interface seal (between mating connector halves) to provide a complete environmental seal and maintain high insulation resistance throughout the connector lifetime. TE’s MQS connector system is one of the most widely used automotive connector platforms globally, deployed in body electronics, door modules, instrument panels, and other automotive systems.

Single wire seals (SWS) work on the principle of elastomeric compression sealing. The seal is a small rubber grommet with a central hole sized to fit snugly around the wire insulation, and an outer diameter sized to create an interference fit with the seal cavity in the connector housing. When installed, the seal is compressed both radially (between the wire insulation and the cavity wall) and axially (between housing features), creating a multi-lip seal that prevents moisture, dust, and contaminants from passing through the wire entry point. The elastomeric material (typically silicone or EPDM rubber compound) is chosen for its ability to maintain elasticity and sealing force over a wide temperature range, its resistance to automotive fluids, and its long-term durability. The multi-lip design provides redundant sealing surfaces, ensuring reliable sealing even if one seal lip is compromised. Color coding (yellow in this case) helps identify the wire size range the seal is designed for, preventing assembly errors. When combined with the interface seal between mating connector halves, the single wire seals create a fully sealed connector system that can achieve IP67, IP68, or higher ingress protection ratings. This is essential for automotive connectors used in locations exposed to moisture, such as door modules, exterior lighting, under-hood sensors, and under-chassis components.

The 967067-2 is a single wire seal (grommet), not a connector with pins. Its physical characteristics:

• Type: Single Wire Seal (SWS) — cylindrical elastomeric grommet
• Wire Hole: Central bore sized for 0.50-0.75mm² wire insulation diameter
• Outer Diameter: Sized for 3.45mm seal cavity in MQS connector housings
• Seal Lips: Multiple outer sealing lips for cavity wall sealing
• Inner Seal: Inner sealing surface for wire insulation contact
• Color: Yellow (identifies wire size range)
• Material: Elastomer (rubber compound, SAE J200)

Installation: The seal is threaded onto the wire before the terminal contact is crimped. Once the terminal is crimped and inserted into the connector housing, the seal seats in the rear seal cavity of the housing, providing the wire entry seal.

• Sealed MQS Connector Systems: The primary application — used in all sealed MQS automotive connectors to provide wire entry sealing against moisture and contaminants
• Door Module Connectors: Critical for door wiring connectors where the connector passes through the door sheet metal and is exposed to water splash, humidity, and road spray
• Exterior Lighting Connectors: Used in headlight, taillight, and fog light connectors to prevent moisture ingress that could cause corrosion and electrical failures
• Under-Hood Sensor Connectors: Deployed in engine compartment sensor connectors where temperature cycling, humidity, and chemical exposure require robust sealing
• HVAC Actuator Connections: Used in heating/AC system connectors near the firewall and evaporator housing where condensation may occur
• Seat Module Wiring: Provides sealing for seat wiring harness connectors that may be exposed to moisture from footwell areas and window water runoff
• Chassis Sensor Connections: Used for under-vehicle sensor connectors (ABS wheel speed, brake wear, etc.) exposed to road splash, salt, and debris
• Convertible/Open-Top Vehicle Wiring: Essential for connectors in convertible and open-top vehicles where interior wiring may be exposed to rain and moisture
