Single Wire Seals

For Yellow Silicone Connector Seals Guoming Rubber makes one thing: silicone connector seals. Wire seals, cavity plugs, gaskets, protective boots — all molded in-house, on our own tooling, no third parties. Lip tweaks, color changes go straight to production — no approvals, no handoffs. Standard stock ships within 48 hours. Every seal passes automated optical inspection; tensile, compression set, and heat aging tests run in our on-site lab, right next to the line. RoHS compliant across the board. Let's talk.

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.
