The 8-pin waterproof aviation connector is a circular bulkhead connector with eight gold-plated contacts in a machined stainless steel shell. It passes power and signal cores through a pressure housing wall while keeping the sealed volume dry, and is supplied as a mated pair or as plug / receptacle separately.

Product Highlights
- 8 contacts in one penetration: eight gold-plated copper-alloy contacts carry power and signal circuits through a single housing wall.
- Stainless steel shell: machined corrosion-resistant shell with a threaded coupling nut for panel or bulkhead mounting.
- Double sealing: O-ring face seal plus potted wire exit keep the seawater side isolated from the electronics bay.
- Numbered pigtail: rear pigtail wires are sleeved and numbered, so the harness can be wired up without a continuity hunt.

Structure & Sealing
The receptacle threads through the pressure housing wall and is secured with a lock nut; the mating plug locks onto it with a threaded coupling. The face seal is an O-ring seated in the receptacle flange, and the rear of the contact block is potted so water cannot wick along the pigtail. Wire exits are individually sleeved and numbered for error-free hook-up.
