The part number **322C512-51/164-0-CS7168** identifies a specific high-performance heat-shrinkable molded part, typically manufactured by **TE Connectivity (Raychem)**. These components are used in aerospace, defense, and high-reliability industrial applications for cable harness strain relief and environmental sealing. --- ## Technical Specifications Breakdowns The alphanumeric string describes the shape, material, and specific modifications of the adapter boot. | Component Segment | Description | Details | | :--- | :--- | :--- | | **322C512** | **Basic Part Number** | Identifies the shape: L-shape (90-degree) transitional boot or lipped adapter. | | **-51** | **Material Code** | **EPB (Ethylene Propylene Blend)**: Chemically resistant, flame-retardant, and suitable for high temperatures. | | **/164** | **Adhesive/Coating** | Pre-coated with a specific high-performance epoxy or hot-melt adhesive for sealing. | | **-0** | **Color Code** | Standard **Black**. | | **-CS7168** | **Customer Special** | Indicates a custom modification or specific packaging requirement for a client. | --- ## Key Characteristics ### 1. Material Properties (-51) The **-51 material** is specifically designed for: * **Chemical Resistance:** High resistance to hydraulic fluids, aviation fuels, and lubricating oils. * **Temperature Range:** Typically operates from **-55°C to +150°C**. * **Durability:** Excellent mechanical strength and abrasion resistance. ### 2. Physical Design * **Lipped Boot:** The "C" in the prefix usually denotes a lipped design that locks into the groove of a circular connector adapter. * **Strain Relief:** Prevents cable breakage at the connector interface by distributing mechanical stress. * **Environmental Sealing:** When heated, the boot shrinks and the internal adhesive (/164) melts, creating a water-tight and dust-tight seal (IP67/68 rated). --- ## Typical Applications 1. **Military Ground Vehicles:** Protecting wiring harnesses in harsh terrains. 2. **Aerospace:** Used in engine compartments and avionics bays where fluid exposure is common. 3. **Marine:** Sealing connectors against salt spray and moisture ingress. ---
