Advanced technology - yet easy to use
SLIPSIL is the newest generation sealing plugs of Beele Engineering. A plug that is easy to install - lubricate and push and the plug slides in! SLIPSIL plugs offer a substantial technical improvement with regard to sealing capacity and tolerances.
The new SLIPSIL plugs have an aesthetic and well recognizable outlook with a redesigned profiling. The design of profiling and the use of a rubber grade with a proper flexibility, hardness and compression set offer excellent long term behaviour.

The leveled outside profiles of the plug secure a proper surface contact inside the conduit and finally the inner ribs have a "sliding" design, not only for ease of installation, but also to create sufficient grip.

SLIPSIL sealing plugs are clearly marked with the CSD logo and the SLIPSIL mark on the flange. Extra feature for recognition is the shape of the flange. The specific terracotta colour of the SLIPSIL plugs is unique for this product line. Due to the new design the SLIPSIL plugs can be exposed to fairly high pressure loads directly after installation.

NOFIRNO - advanced rubber grade
SLIPSIL sealing plugs are made of the advanced rubber grade NOFIRNO. This rubber is halogen free, does not harden during service life, has outstanding weathering properties, does not shrink during fire exposure, has an oxygen index of 55% (>30 is flame retardant) and a low smoke index.

NOFIRNO rubber can be used in a very wide temperature range from -50° C up to 
+180° C. That means that with one rubber grade almost all sealing conditions can be covered now.

Numerous fire tests have shown that the rubber NOFIRNO plugs withstand fire and thermal loads without showing dramatic colour change or carbonization at the unexposed side. At the exposed side the rubber will NOT be consumed by the fire due to the protective layer and char formed. This means that the plug stays in place there.

NOFIRNO rubber is traceable to prevent counterfeiting and to guarantee users that they get the CSD quality they expect.

NOFIRNO - Optimum fire safety guaranteed.
