The 357-series part numbers are associated with VW Group electrical components from the Golf Mk3\/Mk4, Passat B4\/B5, and Audi A4\/A6 generations. Wire seals are the primary IP67 sealing element in waterproof automotive connectors — each conductor passes through its own wire seal, which compresses around the wire jacket to prevent water ingress. Wire seals must be replaced whenever a terminal is replaced.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVW\/Audi Part Number:\u003c\/strong\u003e 357972842\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Individual wire seal \/ plug seal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Silicone rubber (heat and chemical resistant)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e IP67 sealing around individual conductors at housing rear entry\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e VW Group waterproof connector assemblies (Golf Mk3\/Mk4, Passat B4\/B5, Audi A4\/A6)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Range:\u003c\/strong\u003e Specific wire OD range (verify against VW parts catalog)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eVW\/Audi Wire Seal Part Numbers\u003c\/h3\u003e\n\u003cp\u003eVW Group uses multiple wire seal part numbers for different wire OD ranges and connector series:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e357972841:\u003c\/strong\u003e For smaller wire OD (0.35–0.5mm² \/ 22–20AWG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e357972842 (this product):\u003c\/strong\u003e For medium wire OD (0.5–1.0mm² \/ 20–18AWG)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e357972843:\u003c\/strong\u003e For larger wire OD (1.0–1.5mm² \/ 18–16AWG)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eSelect the wire seal that matches the wire jacket OD.

Slide the wire seal onto the wire before stripping and crimping. 2. Position the seal at the correct distance from the wire end (per the VW connector assembly instructions). 3. Strip the wire and crimp the terminal. 4. Insert the terminal into the housing — the wire seal enters the housing cavity with the terminal. 5. Install the back cover to compress the wire seal. The seal must be on the wire before crimping — it cannot be installed after the terminal is crimped.\u003c\/p\u003e\n\n\u003ch4\u003eWhich VW\/Audi connectors use 357972842 wire seals?\u003c\/h4\u003e\n\u003cp\u003e357972842 wire seals are used in VW Group waterproof connectors throughout the Golf Mk3\/Mk4, Passat B4\/B5, Audi A4 B5\/B6, and related platforms. Common applications: engine bay sensor connectors, underbody connectors, door connectors (lower section), and exterior lighting connectors. Cross-reference the connector housing part number in the VW parts catalog to verify the correct wire seal part number.\u003c\/p\u003e\n\n\u003ch4\u003eCan I use 357972842 in non-VW connectors?\u003c\/h4\u003e\n\u003cp\u003eOnly if the wire seal dimensions match the connector housing cavity geometry. Wire seals are sized for specific connector housing cavities — a VW wire seal may not fit correctly in a non-VW connector housing.
