Dirko Gray

The permanently elastic, temperature-resistant, silicon-based, universal sealing compound

Temperature stability: -50°C to +180°C.

This extremely versatile, high-strength sealing compound seals surfaces, gaps and cracks reliably, even where there is movement. Dirko’s viscosity and absolutely permanent elasticity rapidly stops leakage of oil, water and air. Even structural parts with hairline cracks are made functional again within minutes. Dirko is resistant to ozone, sunlight, extreme weather conditions, hot and cold water, seawater, greases, mineral oils (also additives), aliphatic hydrocarbons, detergents and numerous chemicals. These advantages make Dirko equally suitable for use on its own, as a sealant applied from the exterior between surfaces without disassembly, or in combination with flat gaskets.

Application:

Carefully remove any existing sealant residues using a plastic spatula. Clean and degrease the sealing surfaces. Apply Dirko. Skin formation time is appox. 5 – 10 minutes, so for “Wet-in-wet” assembly, i.e. the parts are joined immediately before a skin begins to form, be sure to adhere before that time.

At WR we use Dirko to seal the case halves and cylinder bases.
