7222-2418-30 / QLW-A-1M / QLW-A-1F Automotive Waterproof Wiring Connector — Male & Female Set
The 7222-2418-30 (housing assembly) with QLW-A-1M (male terminal) and QLW-A-1F (female terminal) is a sealed waterproof automotive connector set designed for moisture-sensitive wiring harness applications. The sealed housing with individual wire seals provides reliable ingress protection for underbody, wheel well, and exterior lighting circuits where direct water exposure is expected. Manufactured to OEM mating dimensions for direct replacement compatibility across multiple vehicle platforms.

Sealed Connector Design — Key Features
- Individual wire seals (QLW-A) — rubber wire seals on each terminal provide IP67-equivalent moisture protection at the wire entry point, preventing water wicking along the wire into the connector
- Sealed mating face — connector body seal at the mating interface prevents water ingress when the connector is fully engaged
- Positive latch retention — audible click confirms full engagement; resists pull-out under vibration and thermal cycling in underbody applications
- OEM part number compatibility — 7222-2418-30 / QLW-A terminals are manufactured to OEM mating dimensions for direct replacement

Frequently Asked Questions
Q: How do I install the wire seal correctly?
Thread the wire seal (QLW-A) onto the wire before stripping the insulation and crimping the terminal. After crimping, slide the wire seal up to the terminal’s insulation barrel. When the terminal is inserted into the housing, the wire seal seats in the housing entry hole, creating the waterproof seal. If the wire seal is installed after crimping, it cannot pass over the terminal and the connector will not seal properly.
Q: What IP rating does this connector achieve?
With correctly installed wire seals and a fully engaged connector body seal, the 7222-2418-30 / QLW-A connector achieves IP67 (dust-tight, protected against temporary immersion in water up to 1m for 30 minutes). This is the standard requirement for underbody and wheel well automotive connectors.
Q: Can I reuse the wire seals after disconnecting the connector?
Wire seals can typically be reused if they are undamaged and have not been over-compressed. Inspect the seal for tears, deformation, or hardening before reuse. If in doubt, replace with new wire seals — a failed wire seal is the most common cause of waterproof connector failure in service.
