Keep Your Electrical Connections Dry

Written by Kimball Midwest | April 10, 2025

We’ve all heard the saying: April showers bring May flowers. Even though April has just begun, many areas of the country have seen significant rain. Regardless of if you have seen heavy rains or if it’s been dry, one thing remains the same: water has no place messing with your equipment or business.

 

One place you don’t want water is in your electrical connections. Did you know that most unplanned maintenance is due to electrical failure? Water and moisture in connections can lead to failure, which can be a costly fix. That means keeping electrical connections dry is non-negotiable.

 

To preserve the electrical connections in your shop, you’ll want to protect them with top-of-the-line waterproof products. We’ve gathered a few Kimball Midwest products that will help you keep unwanted water and moisture out.

 

Heat-Shrink Tubing and Terminals

 

To protect your electrical connections from environmental factors like rain, look no further than heat-shrink tubing and terminals.

 

Kimball Midwest is proud to offer a variety of terminals that will lock out moisture, like our Pro-Tech™ Nytrex terminals. These heat-shrink terminals are ideal for secure, sealed wire connections and can be sealed easily with a lighter, heat gun, etc. The Therma-Flow sealant locks out moisture, preventing corrosion, and provides strain relief to prevent wire pull-out. It also features transparent tubing that allows for visual inspection of the wire and terminal connection.

 

We also offer heat-shrink tubing for all your electrical needs. Designed to shrink and seal around wires, the tubing creates a tight, protective barrier that stands up to not only water but also dust, chemicals and mechanical strain.

 

While there are three grades of heat-shrink tubing (single wall, dual wall and heavy dual wall), for optimal protection from water and a weathertight seal, dual wall and heavy dual wall tubing are your best choice.

 

Both our dual wall and heavy dual wall tubing feature a Therma-Flow liner as well as a 3:1 shrink rate. While dual wall tubing is perfect for general applications, heavy dual wall tubing is ideal for heavy-duty equipment like agricultural equipment.

 

Electro-Seal Sealing Compound

 

This is a great tool that permanently seals, waterproofs and insulates connections. Its 100% mastic insulating compound will easily conform to any shape or contour. It adheres to itself, all cable insulations and metals to form a positive, water-tight seal.

 

Electro-Guard Moisture & Corrosion Barrier

 

This handy product provides a penetrating molecular film that seals and protects electrical systems, helping prevent premature electrical failure. It forms a moisture barrier that locks out water and moisture. It also displaces water from wet electrical systems to restore operation.

 

Electro-Maxx™ Dielectric Grease

 

This dielectric grease insulates and protects vital electrical connections from moisture and corrosion. It features high dielectric strength, but it also seals high energy electrical systems.

 

Additionally, it sprays out thin and quickly sets up into a gelled grease making, it ideal for hard-to-reach areas where product penetration is essential.
