Outdoor installations don't forgive connection failures. Cablein's T Splitter Waterproof Plug is built for that reality. The housing is impact-resistant PA66 thermoplastic, sealed with precision-cut silicone O-rings. Every unit hits IP67/IP68, with insulation resistance above 200MΩ.
We use a reduced trapezoidal junction design that spreads mechanical stress across the branch point. That improves pull-out strength and keeps the splitter working reliably from -40℃ to 150℃. The product is certified to ETL and CE standards under our ISO9001:2015 quality system. Wire gauge compatibility is customizable—main lines from 7–11mm, branch lines from 6–11mm. LED lighting, industrial automation, marine applications—anywhere moisture ingress means expensive downtime, these fit right in.

A T Splitter Waterproof Plug is a three-way electrical connector that splits one power or signal line into two outputs without compromising environmental protection.
Unlike traditional junction boxes, ours eliminates the capillary effect—where water creeps along cable jackets into electronics. The factory-molded design removes assembly errors. You get plug-and-play reliability in seconds.
Manual field joining falls flat quick outside. Tape debases. Heat-shrink tubing splits. Our overmolded arrangement stops dampness some time recently it comes to your circuits. That implies less benefit calls and lower lifetime costs.

1. Smart Urban Lighting Networks
LED street lamps,facade wall-washers, block after block. Parallel distribution handles thermal expansion as seasons change. Rain, snow, heat—lights stay on.
2. Industrial IoT & Factory Automation
Sensor signals on humid floors, chemical zones. Standard connectors corrode. Ours don't. Signal stays clean.
3. Marine & Aquaculture Installations
Offshore wind, underwater sensors. Salt spray, submersion pressure, constant. IP68 splitters keep transmitting, even fully underwater for long stretches.
