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 through the rear of the housing. Wire seals are consumable items — they must be replaced whenever a terminal is replaced, as removing a terminal from the housing typically damages or displaces the wire seal.\u003c\/p\u003e\n\n\u003ch3\u003eKey Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 1544316-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer:\u003c\/strong\u003e TE Connectivity\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\u003eWire Range:\u003c\/strong\u003e Specific wire OD range (verify against datasheet)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWire Seal Function in Waterproof Connectors\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary sealing element:\u003c\/strong\u003e The wire seal compresses around the wire jacket when the terminal is inserted into the housing cavity.

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 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 and seats in the cavity’s seal groove. 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 onto the wire.\u003c\/p\u003e\n\n\u003ch4\u003eWhat happens if I reuse an old wire seal?\u003c\/h4\u003e\n\u003cp\u003eWire seals degrade over time from heat cycling, chemical exposure, and compression set. A reused wire seal may not compress correctly around the wire jacket, allowing water ingress. Always use new wire seals when replacing terminals. Wire seals are low-cost consumables — the cost of a new seal is negligible compared to the cost of connector failure from water ingress.\u003c\/p\u003e\n\n\u003ch4\u003eHow do I select the correct wire seal size?\u003c\/h4\u003e\n\u003cp\u003eWire seals are sized for a specific wire OD range (e.g., 1.0–1.5mm OD, 1.5–2.0mm OD). Measure the wire jacket OD with a caliper and select the seal sized for that OD range. Using the wrong size will not achieve IP67. Cross-reference 1544316-2 in the TE Connectivity catalog to verify the wire OD range and compatible connector housings.\u003c\/p\u003e\n\n\u003ch3\u003eTypical Applications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal replacement:\u003c\/strong\u003e New wire seals required whenever terminals are replaced in waterproof connectors\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHarness manufacturing:\u003c\/strong\u003e Wire seals for new waterproof connector assemblies\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCommercial vehicles:\u003c\/strong\u003e Wire seal replacement during connector repair on trucks and buses\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomotive workshops:\u003c\/strong\u003e Workshop stock for TE Connectivity connector wire seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePackage Contents\u003c\/h3\u003e\n\u003cp\u003eAutomotive connector wire seals, 1544316-2 (quantity as selected).
