LiquaTight waterproof electrical connectors for waterproof connections - Remke Blog

As the heat of summer in at its peak, it’s a great time to examine your submerged electrical connectors, or any connection that is exposed to water, high humidity or other elements that cause corrosion.

It’s the time of year when the weak links make their presence known. Don’t let your electrical connectors be the weakest link!

If you’re having problems with a liquid-tight fitting, and replacing or servicing them regularly, take a look at the materials and construction. There is likely a component of that connection that is failing. By selecting the right components, you’ll ensure long-lasting connectivity and reliability.


Waterproof Electrical Connector Materials

Tuff Seal Cord Grips and Connectors - Remke Blog304 Stainless Steel – tough and corrosion resistant, 304 SS is ideal for high-moisture applications and is the standard for waterproof electrical connections.

316 Stainless – heavy-duty corrosion resistance, 316 SS is made for superior protection from chemicals and acids, as well as moisture and a variety of abrasives.

Nickel-plated aluminum – the appearance of polished stainless steel without the cost. It protects against corrosion, wear, friction and contamination under severe conditions.

Nylon – lightweight, durable and corrosion resistant, Nylon connectors are ideal for damp environments.

Valox – suitable for FDA regulations, Valox provides superior corrosion resistance in applications that require washdowns.

If you deal with water and electricity, chances are you have other environmental concerns as well. Check out this infographic: Cable Strain Relief in Harsh Environments >
