What This Part Is and Where It Goes
The TE Connectivity 1587530-1 is a cable seal for HVA size A-B circular connectors. It is an accessory, not a connector body or terminal — it seals the cable entry point on the back of the connector housing, keeping moisture and debris out of the contact cavity. The yellow silicon material provides flexibility for wire routing and holds up to the temperature range typical of underhood and industrial circular connector applications. This seal is designed specifically for TE's HVA (High Voltage Automotive) circular connector family, size A-B. The HVA series is used in hybrid and electric vehicle powertrain interconnects, battery pack connections, and high-voltage industrial equipment where a sealed, circular interface is required. The 1587530-1 fits the cable-entry side of the connector assembly, mating with the corresponding HVA plug or receptacle housing.
Material and Build Notes
The seal is molded from silicon, a material chosen for its wide operating temperature range, chemical resistance to oils and coolants, and compression set resistance that maintains sealing force over years of service. Packaged in bulk, so it feeds into manual or semi-automated assembly lines without reel or tape requirements. For high-volume automated seal insertion, verify that your pick-and-place or bowl-feeder tooling is compatible with bulk-fed silicon seals — the material's compliance can cause feeding issues if the tooling is set up for rigid plastic parts.
