📌 Product Overview

The Corrosion-Proof Connection Solution.

Metal connectors eventually corrode, but plastic lasts. Victory Technology’s Plastic 7-Pin Plug & Socket Set is the lightweight, rust-proof alternative for trucks and trailers operating in harsh environments.

Engineered to ISO 1185 (N-Type) and ISO 3731 (S-Type) standards, this set ensures a reliable link for your taillights, brake lights, and turn signals. Manufactured in our Zhuji Aoke facility from Reinforced Automotive-Grade Plastic, the housing is impervious to road salt, moisture, and mild chemicals, making it the ideal choice for coastal fleets and winter operations.

🔹 Why Choose Victory Plastic Connectors?

  • ✅ 100% Rust-Proof & Corrosion Free:The biggest advantage of plastic. Unlike zinc alloy, this high-strength plastic housing will never oxidize or seize up. It is the preferred choice for boat trailers, agricultural sprayers, and trucks running on salted roads.
  • ✅ ISO Standard Compatibility:Universal fit. Whether you are replacing a damaged plug on a farm tractor or a semi-trailer, our connectors follow standard 7-pin wiring configurations (12V/24V), ensuring compatibility with existing systems.
  • ✅ High-Conductivity Brass Terminals:Plastic body, premium internals. We use solid Brass Pins and Terminals to ensure low electrical resistance and stable signal transmission for your lighting circuits.
  • ✅ Weather-Resistant Design:The socket features a Spring-Loaded Flap that snaps shut to seal out dirt and water when uncoupled. The plug includes a secure Cable Clamp to prevent wire strain and water ingress.
