Molex part numbers in the XXXXX-XXXX format identify Molex-manufactured connector accessories. Back covers are critical for achieving IP67 sealing and secondary terminal retention in waterproof automotive connectors used in engine bay, underbody, and exterior applications.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 34951-1210\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e Molex\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComponent Type:\u003c\/strong\u003e Connector back cover \/ rear seal \/ secondary lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e PA66 nylon, flame retardant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e IP67 rear seal + secondary terminal retention\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Specific Molex female socket connector housing (verify compatibility)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMolex Connector Back Covers — Identification\u003c\/h3\u003e\n\u003cp\u003eMolex back covers are specific to individual connector housing part numbers.

Press the back cover firmly onto the housing until it clicks into the locked position. Verify the back cover is fully seated — a partially installed back cover will not compress the wire seals correctly and will not achieve IP67. For Molex connectors with a lever-type back cover, engage the lever after pressing the cover onto the housing.\u003c\/p\u003e\n\n\u003ch4\u003eWhat happens if the back cover is missing or damaged?\u003c\/h4\u003e\n\u003cp\u003eWithout the back cover: (1) the connector will not achieve IP67 sealing — water enters through the rear; (2) terminals may push back under cable pull forces; (3) the connector does not meet OEM specifications. Always replace a missing or damaged back cover before returning the connector to service. Operating a waterproof connector without its back cover in an outdoor or underbody location will cause terminal corrosion and connector failure within months.\u003c\/p\u003e\n\n\u003ch4\u003eCan I reuse a Molex back cover after removal?\u003c\/h4\u003e\n\u003cp\u003eYes, if undamaged. Inspect for cracks, deformed locking tabs, and damaged sealing surfaces. A back cover that no longer clicks firmly into the locked position should be replaced. Molex back covers are designed for multiple installation cycles but have a finite locking tab life — replace if retention force is reduced.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive repair:\u003c\/strong\u003e Replacing missing or damaged back covers on Molex waterproof connectors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHarness manufacturing:\u003c\/strong\u003e Back covers for new Molex connector assemblies\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial vehicles:\u003c\/strong\u003e Back cover replacement during connector repair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive workshops:\u003c\/strong\u003e Workshop stock for Molex connector accessories\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e1 piece — automotive connector back cover 34951-1210 (Molex).
