If your wiring runs outdoors or takes a beating on the factory floor, plastic connectors just don't hold up. The LP16 8-Pin Full Metal Waterproof Aviation Connector Solder from Cablein Technology is built for that reality. It uses a full metal shell around 8 solder pins, holding an IP68 rating while handling 5A at 250V. The seal fits 7 to 9 mm cables, so moisture stays out and your connections stay tight.

Full Metal Shell
Forget about a plastic shell with a thin metal ring. This housing is solid metal from top to bottom. That means it won't shatter when dropped, holds up to high heat, and naturally blocks EMI when it's sitting next to drives and inverters in a cabinet.
8-Pin Solder Termination
Eight pins give you room for mixed power and signal runs. We use solder joints because they offer lower contact resistance than screw terminals. It takes a few extra minutes to wire, but the connection won't shake loose when the machine is running.
IP68 Sealing for 7-9mm Cables
Thick cables often break the seal on cheaper connectors. We sized the silicone ring specifically to fit cables with a 7–9 mm outer diameter. Once you screw the coupling down tight, that ring crushes just enough to form a solid barrier—it won't leak even if the equipment gets hosed down or caught in a downpour.
Threaded Locking
Push-pull plugs have a bad habit of working themselves loose when machines start shaking. That's why we went with a threaded lock here—the plug and socket stay locked tight until someone actually twists them apart.

Real-World Applications You Can Count On
Industrial Control Cables
When running control lines between machine modules, the LP16 8-Pin Full Metal Waterproof Aviation Connector Solder is what you want in place. The metal shell and IP68 seal keep moisture and interference out on the factory floor.
Outdoor Lighting Arrays
Rain and temperature swings are just normal conditions for outdoor lighting. With a -40°C to +85°C operating range, this connector keeps power stable from freezing winters to scorching summers.
Food Processing Lines
Washdowns are unavoidable in food plants. Plastic plugs get brittle and crack over time. The metal housing on this LP16 handles cleaning chemicals and physical abuse much better.
Marine and Dockside
Salt spray destroys cheap connectors fast. The full metal body and sealed design give you solid protection against corrosion on dockside gear and marine electronics.
Automotive Test Rigs
Vibration and moisture are everywhere in vehicle testing. Solder joints and threaded locks make this connector a reliable choice for temporary test setups.
Before anything leaves our factory, it goes through strict ISO9001:2015 checks. We don't just test the electrical specs; we dunk the connectors in water to confirm the IP68 seal holds at the 7-9mm cable range. We also pull on the solder joints and check the threads. It means the LP16 8-Pin Full Metal Waterproof Aviation Connector Solder you get is ready to install without extra fuss.

Q: Can I get this connector with a different number of pins?
A: Yes, we make them in 2, 3, 4, 5, 7, 8, and 9 pin versions. Tell us what your application needs.
Q: Will my cable fit?
A: As long as your cable's outer diameter is between 7 mm and 9 mm, the standard sealing ring will work.
Q: Can I test one before placing a big order?
A: Absolutely. We recommend getting a sample first. You can check the fit and the seal on your actual cable before committing to a full run.
Q: Do I need to ground the metal housing?
A: If your equipment requires shielding or earth continuity, yes, you should ground the metal shell.
