Single Wire Seals

Single wire seals are a very common seal for automotive connectors and are available in two types: single wire seals and cavity plugs.

People often ask,What is the difference between Single wire seals and cavity plug?

Single Wire Seals

Single wire seals allow cables to pass through and surround the cable, providing waterproof and dustproof protection at critical interfaces. Cavity plugs block the cavity, preventing water, dust, and oil from entering the automotive connector.

Gray Single Wire Seal

Zhejiang Guoming Rubber Technology Co., Ltd. has spent years deep in the rubber sealing field, and we've learned one thing the hard way: automotive connector failures aren't caused by big problems — a single grain of dust, a drop of moisture is enough to interrupt the signal. That's exactly why we refined the 7165-1648 Gray Single Wire Seal. It may be small, but it's the last line of defense for wiring harness waterproofing and dust protection. From the engine bay to chassis routing, it works where you can't see it, making sure every signal transmits clean through. It's the ideal partner for automotive wiring harnesses and connectors — and many customers have given us great feedback after putting it to use.

Brown Silicone Seal Plug

Zhejiang Guoming Rubber Technology Co., Ltd. has spent years in the connector sealing space, and one thing hasn't changed: unused cavities on a connector housing are the easiest entry points for water — and the easiest to overlook. You can design the best waterproof connector in the world, but one unsealed cavity, and the whole harness loses its IP rating. The 7161-9787 Brown Silicone Seal Plug does exactly one job — plugs the holes that don't need a wire, and gives water nowhere to go.

Green Silicone Connector Seals

Green Silicone Connector Seals:A connector housing can pack twenty cavities — but one wire seal fails, and the whole harness is suspect. That's exactly why we sweat the details on the 967067-1. Triple-lip seal geometry, high-tear silicone. It holds its shape through hot-cold cycles without deforming, fits the cavity tight enough to waterproof yet slips in smooth — no jamming, no wrestling. That's the standard we hold every Green Silicone Connector Seal to. Cut and manufactured at Guoming Rubber.
