Wurth SUPER RTV Silicone sealing compound, BLACK high temp 200ml

High-quality adhesive and sealing compound for use in industry and the automotive sector.


Excellent resistance to chemicals

  • Can also be used in critical areas in which the seal comes into contact with various liquids
  • Outstanding resistance to engine oil and transmission oil, refrigerant and anti-freeze agent

Non-acidic hardening system

  • Non-corrosive, therefore has no negative impact on electronic components and on lambda probes

Sealant in compressed-air can

  • Easy to dispense without additional aids
  • The fine beads allow the product to be applied uniformly

When sealing e.g. oil pans and gearboxes it is vital that no sealant gets into the interior. For this reason we recommend to apply the sealant on a joining part surface. Join both parts and then carefully press by hand and lightly slide against each other. Afterwards separate the parts again and then remove the sealant that has gone inside. Join the components again within a max. of 5 minutes and tighten firmly. Before commissioning, observe the hardening time (depending on the sealant thickness).


Optimum adhesion to dry, clean and dust-free surfaces. The old sealant must be removed in full from the surface.
