Grafi-sil valve balls are made of a special silicone rubber. The valve balls ensure 100% tightness in steam model construction with their check valves, feed water pumps and injectors, even when the ball sockets are removed or dirty. They can be used in steam, water and oil pipes and are absolutely noise-free. The following valve ball diameters are available: 4mm Grafi-sil valve balls 5mm Grafi-sil valve balls 6mm Grafi-sil valve balls 8mm Grafi-sil valve balls 10mm Grafi-sil valve balls 12.7mm Grafi-sil valve balls 15,2mm Grafi-sil valve balls You can of course also retrofit the Grafi-sil balls into your existing components. The maximum ball diameter must always be selected. Sufficient is already 0.3mm distance between ball and armature diameter. The graphi-sil spheres can be used up to a temperature of 400 ° C. We use the Grafi-sil spheres, among other things, as outlet valve balls for our flame eaters. We offer you a sample set with 2 balls of each size - with a price advantage of 20% !!! 2x4mm / 2x5mm / 2x6mm / 2x8mm Whoever has used Grafi-sil balls does not take anything else! !!! Grafi-sil valve balls are also used in machine and plant construction !!!

The Abil N sealing material of Elring is a cellulose-based sealing paper with an NBR binder. It is suitable for sealing cylinder heads in combustion engines or cylinder covers in steam engines or Stirling engines. Abil can be used to seal against cooling water, oils, fuels and steam. If you want to use the sealing paper to seal steam or air, oil the finished seal well. With this material you can make your own seal. The 0.5mm thick sealing material can be cut perfectly with scissors, perforated iron or knife.
