— Advantages

Permanent bonds that hold even underwater

01

Waterproof protection

The heat shrink tubing completely seals the connection and reliably protects against moisture, splashing water, and corrosion — certified to IP67.

03

Extreme temperature resistance

Works reliably from -55 °C to +125 °C — even in engine compartments, outdoor areas, and marine environments with extreme temperature fluctuations.

02

Stable copper core

The dense copper core ensures optimal current flow without voltage drop and provides a mechanically robust, durable connection.

04

Simple processing

Insert the cable, heat it with a heat gun — the tubing shrinks and the solder flows, without tools or a soldering station.

These 4 strengths make the solder connectors a permanent solution

Whether cable repair in the engine compartment, retrofitting on the boat, or outdoor installation — the waterproof solder connectors impress with four specific advantages that conventional connection methods cannot offer.

1

No tools needed

A simple heat gun is enough — the tube shrinks, the solder flows, the connection is tight and done.

2

Permanently waterproof

The IP67 sealing reliably keeps out moisture, saltwater, and condensation, even with continuous outdoor exposure.

3

Safe current flow

The copper core ensures a low-resistance connection that does not cause voltage drop even under vibration and temperature fluctuations.

4

Sorted & within reach

The color-coded connectors in the clear plastic box are sorted by cross-section and ready to use immediately.

Areas of application

Versatile for use anywhere it gets wet

These solder connectors are the right choice wherever reliable, waterproof connections are crucial. Whether in the vehicle engine compartment, on the water, or in outdoor installations — the connectors withstand harsh conditions where ordinary terminal blocks or crimp connectors quickly reach their limits.

Automobile & Motor Vehicles

Automobile & Motor Vehicles

Perfect for cable repairs, retrofits, and electrical installations in the engine compartment, where heat and vibration require durable connections.

Marine & Boot

Marine & Boot

The waterproof IP67 seal reliably protects connections from saltwater, moisture, and harsh conditions on the water.

Outdoor & Garden

Outdoor & Garden

For outdoor lighting, pumps, or security systems, the connectors provide weatherproof protection that withstands wind and rain permanently.

Industry & Workshop

Industry & Workshop

In workshops and industrial use, the connectors enable quick, clean connections without a soldering station — even in tight spaces.

Applications

I used the connectors for wiring my trailer hitch and am very satisfied — after several rainy drives, no problems so far.

Done in seconds with the heat gun, no soldering needed. Just right for someone without much electrician experience.

The connections on my motorboat have now been sitting in saltwater for a whole summer without any corrosion — I'm impressed.

100 pieces are enough for many projects, the box is practical for sorting. The quality is good, but you need a proper heat gun for the best results.
