The back cover serves two functions: (1) it provides the primary rear seal, compressing the individual wire seals around each conductor to achieve IP67 waterproofing; (2) it provides secondary terminal retention, preventing terminals from backing out of the housing under vibration and cable pull forces. Back covers are a critical component of waterproof connector assemblies — a connector without its back cover will not achieve IP67 sealing and may experience terminal push-back.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 13719691\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\u003eApplication:\u003c\/strong\u003e Female socket connector housing (specific housing as per part number)\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 Truck, agricultural, and industrial vehicle OEM wiring harnesses\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBack Cover Functions in Waterproof Connectors\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP67 rear sealing:\u003c\/strong\u003e The back cover compresses the wire seals (individual rubber seals around each conductor) against the housing rear face.

Without the back cover: (1) the connector will not achieve IP67 sealing — water can enter through the rear; (2) terminals may push back under cable pull forces, causing intermittent connections; (3) the connector may not meet OEM specifications for the application. Always install the back cover before mating the connector. If the original back cover is lost or damaged, order a replacement before returning the connector to service.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I install a connector back cover?\u003c\/h4\u003e\n\u003cp\u003eAfter loading all terminals into the housing and verifying each terminal is fully seated (pull-test each wire): align the back cover with the housing rear face, ensuring the wire seals are correctly positioned in their cavities. 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.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I identify the correct back cover for my connector?\u003c\/h4\u003e\n\u003cp\u003eThe back cover part number (13719691) is specific to a particular connector housing. Cross-reference with the vehicle’s parts catalog or the connector housing’s part number to verify compatibility. Back covers are not interchangeable between different connector housings — even connectors with the same pin count may use different back cover designs.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial trucks:\u003c\/strong\u003e Replacement back covers for damaged or missing connector rear seals\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAgricultural equipment:\u003c\/strong\u003e Connector assembly completion for harness repair\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive workshops:\u003c\/strong\u003e Workshop stock for common connector back cover replacements\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHarness manufacturing:\u003c\/strong\u003e Back covers for new connector assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003e1 piece — automotive connector back cover 13719691.
