Sikaplan/Sarnafil various

The S-Duoseal Universal Coupling is used with S-Drain PVC and Sarnafil T Drain. It provides an economic method of solving the problem of sealing a new S-Drain PVC or Sarnafil T Drain into an existing roof drain during a roof refurbishment.

Available in a range of sizes, these couplings are simple to install. The silicone lubricant supplied is applied to the Sarnafil G/S or TG/TS rainwater outlet spigot and the coupling slide over. The outside fins of the coupling are then lubricated with the silicone sealant and the outlet is inserted into the existing rainwater outlet. Once the outlet is secured to the substrate, the Sarnafil roof membrane is hot air welded onto the rainwater outlet flange.

• Ease of application
• Secure and durable backflow seal
• Each S-Duoseal Universal Coupling fits a wide range of sizes
• The Couplings work for most existing roof drains, without the need for a spigot and socket connection
