Special Seal
To guarantee quick delivery in high quality, we have introduced several seal masters - CNC lathes with well-proven database that can offer more than 115 computerized standard profiles (non-standard profiles are also easy to produce) at your disposal. Our advanced technology allows us to manufacture most of engineered seal profiles in a timely and most precise manner. Seals are available from 1 to 2,500 mm in outside-diameter.
The combination of Seal master - CNC Lathes and moulded sealing materials allows us to offer wide range of hydraulic and pneumatic seals that could satisfy most of industrial customers in terms of high operational availability and low initial / maintenance cost.
