Automotive Connector Back Cover – 1418985-2, Waterproof Housing Rear Seal for Female Socket Cable Plug

Part number 1418985-2 is a TE Connectivity automotive connector back cover — the rear seal and secondary lock component for a specific TE Connectivity female socket connector housing. The TE Connectivity part number format (XXXXXXX-X) identifies this as a TE-manufactured accessory. This back cover is used in heavy-duty commercial vehicle and industrial wiring harness applications, consistent with the TE Connectivity connector families used in truck, agricultural, and construction equipment.

Key Specifications

• Part Number: 1418985-2
• Manufacturer: TE Connectivity
• Component Type: Connector back cover / rear seal / secondary lock
• Material: PA66 nylon, flame retardant
• Function: IP67 rear seal + secondary terminal retention
• Application: Specific TE Connectivity female socket connector housing in commercial vehicle wiring

Back Cover Critical Functions

• IP67 rear sealing: Compresses individual wire seals against the housing rear face. Without the back cover, wire seals are not compressed and water enters through the rear — the connector will not achieve IP67 regardless of mating face sealing.
• Secondary terminal retention: Locks over terminal lancing lances, preventing push-back under cable pull forces. Critical in commercial vehicle applications where cable bundles are heavy and subject to vibration.
• OEM compliance: Required for the connector to meet TE Connectivity’s IP67 specification and the vehicle manufacturer’s electrical system requirements.

Frequently Asked Questions

How do I verify 1418985-2 is compatible with my connector housing?

Cross-reference 1418985-2 in the TE Connectivity catalog (te.com) to identify the compatible connector housing part numbers. The TE catalog lists back covers as accessories to specific connector housings. Verify the housing part number on the original connector before ordering. If the original back cover is lost or damaged, identify the connector housing part number and cross-reference to find the correct back cover.

What TE Connectivity connector series uses 1418985-2?

The 1418985-2 part number is consistent with TE Connectivity’s heavy-duty connector accessory range, likely associated with the HDP20 or similar heavy-duty series used in commercial vehicle applications. Cross-reference in the TE catalog to identify the specific connector series and compatible housing part numbers.

Can I use a different back cover if 1418985-2 is unavailable?

No. Back covers are specific to individual connector housings — a different back cover will not fit correctly or will not compress the wire seals properly. If 1418985-2 is unavailable, contact TE Connectivity for the current replacement part number — TE occasionally updates part numbers while maintaining backward compatibility. Do not use a back cover from a different connector housing as a substitute.

Typical Applications

• Commercial trucks: Back cover replacement during connector repair on heavy-duty truck wiring
• Agricultural equipment: Connector assembly completion for harness repair
• Construction equipment: Back cover replacement on heavy machinery wiring harnesses
• Automotive workshops: Workshop stock for TE Connectivity heavy-duty connector accessories
