The SWT and Duoflux are specifically designed soldersleeves to splice tin-plated or bare copper stranded wires rated. The insulation of these soldersleeves are made of polyolefin tubing with 2 thermoplastic, color coded, adhesive rings. The rings will melt and flow to seal and encapsulate the inner components, offering an environmental protection.

The biggest difference between the SWT and Duoflux is that the Duoflux has 2 solderrings. One ring is melting at a higher melting point then the other one. When the ring with the highest melting point is melting, you know that the low-temp ring is already flow perfectly and already secures a good connection. Hence, the dual ring structure ensures a quick and good installation.

Both soldersleeve types are available in 4 sizes.
