When you are dealing with field wiring that faces moisture and constant movement, cheap plastic connectors often give out. The LP16 8-Pin Metal+Plastic Waterproof Aviation Connector Solder from Cablein Technology is designed to solve this. It uses a hybrid metal and plastic housing, paired with 8 solder pins. Rated IP68, it handles 5A at 250V and seals cables from 7 to 9 mm. This keeps your power and signal lines safe from the elements.

Metal and Plastic Housing
We didn't go with a full metal shell because it makes the cable too heavy. Instead, this hybrid design gives you the impact resistance of metal where it matters, while the plastic keeps it lightweight. It also provides decent shielding against electrical interference in crowded cabinets.
8-Pin Solder Setup
Eight pins give you plenty of room for running both power and signal wires in one cable. We chose a solder design because it provides lower contact resistance than screw terminals. It takes a bit more time to wire up, but the joint stays solid even when machines are vibrating all day.
IP68 Sealing for 7-9mm Cables
A lot of connectors leak as soon as you use a thicker wire. Our silicone ring is specifically sized for 7 to 9 mm outer diameters. When you tighten the threaded coupling, it compresses properly. This maintains the IP68 protection even if the cable gets pulled or hosed down.
Threaded Locking
Push-pull connectors can easily disconnect on moving machinery. This model uses a threaded coupling to keep the male and female halves locked together. They stay securely mated until you intentionally unscrew them.

Industrial Control Cables
When running control lines between machine modules, the LP16 8-Pin Metal+Plastic Waterproof Aviation Connector Solder does the job well. The IP68 seal keeps damp air from ruining your electronics on the factory floor.
Outdoor Lighting Arrays
Rain and temperature swings are just everyday reality for outdoor lighting. With a -40°C to +85°C operating range, this connector keeps the power flowing from freezing winters to hot summers.
Food Processing Lines
Washdowns are unavoidable in food plants. Standard plastic plugs get brittle and crack. The hybrid housing on this LP16 handles cleaning chemicals much better, giving you a longer service life.
Marine and Dockside
Salt spray eats away at cheap connectors fast. The sealed design and threaded lock give you solid protection against corrosion on dockside gear.
Automotive Test Rigs
When testing vehicles, you have vibration and moisture everywhere. 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 actually dunk the connectors in water to confirm the IP68 seal holds up at the 7-9mm cable range. We also pull on the solder joints and check the threads. It means the LP16 8-Pin Metal+Plastic Waterproof Aviation Connector Solder you get is ready to be installed 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. Let us know 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 perfectly.
Q: Can I test one before placing a big order?
A: Absolutely. We highly 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 parts?
A: If your equipment requires shielding or earth continuity, yes, you should ground the metal components.
