My Buying Guide on ‘7 Flat Trailer Plug’

As someone who has owned and operated several trailers over the years, I have learned the importance of having a reliable and efficient trailer plug. One of the most commonly used trailer plugs is the 7 flat trailer plug, also known as the RV blade or NEMA connector. In this buying guide, I will share my personal experience and knowledge to help you make an informed decision when purchasing a 7 flat trailer plug.

What is a 7 Flat Trailer Plug?

A 7 flat trailer plug is a type of electrical connector that is used to connect the lighting and braking system of a trailer to the towing vehicle. It consists of seven pins which are color-coded for easy identification and connection. The design of this plug allows for a secure connection and efficient transfer of power between the trailer and towing vehicle.

Factors to Consider

When shopping for a 7 flat trailer plug, there are several factors that you should consider in order to make the right choice.

1. Quality

The quality of a 7 flat trailer plug is crucial as it directly affects its durability and reliability. Look for plugs that are made from high-quality materials such as copper or brass, which can withstand harsh weather conditions and resist corrosion.

2. Compatibility

Make sure to check if the plug is compatible with your towing vehicle’s wiring system. Some plugs may require adapters or modifications in order to fit properly, so it’s important to double-check before making your purchase.

3. Number of Pins

Although most 7 flat trailer plugs have seven pins, some may have additional pins for different functions such as electric brakes or reverse lights. Consider your specific needs before choosing a plug with more or less than seven pins.

4. Waterproofing

Since trailers are often exposed to various weather conditions, it’s essential to choose a waterproof 7 flat trailer plug. This will ensure that your electrical connection stays intact even in wet conditions.

Tips for Maintenance

To ensure the longevity and efficiency of your 7 flat trailer plug, here are some maintenance tips that I have learned over the years:

– Regularly clean any dirt or debris from both ends of the plug using contact cleaner.
– Apply dielectric grease on all connections to prevent corrosion.
– Check for any loose connections or damaged wires before each use.
– Replace worn out plugs immediately to avoid any potential hazards.

In Conclusion

Choosing the right 7 flat trailer plug can greatly impact your towing experience by providing a safe and reliable electrical connection between your vehicle and trailer. By considering factors such as quality, compatibility, number of pins, and waterproofing, you can make an informed decision when purchasing this essential piece of equipment for your trailer.
