BGM PRO silicone single seals consist of a 0.5mm thick, high-quality sealing paper. They have an already applied layer of silicone sealing compound. This provides for an increased surface pressure of the seal. In addition, the silicone sealant also seals the cold engine much better due to the permanently flexible sealing compound. Thus the engine always remains tight and the oil where it belongs and where it is useful.

This is especially good if your gasket faces are a bit dodgy!
