K 50
DESCRIPTION
Compact piston seal K 50 is recommended to be used in easy operating conditions at one- or more-part piston constructions according ISO standard. Type K 50 consists of rubber profile ring which is wear resistant. At the sides fo NBR ring are used two split back-up rings from nylon. In addition there are used the guiding rings on each side of the NBR ring. Guiding rings are also split and made from a modified nylon. The seal is providing very good sealing effect of elastic sealing ring, good extrusion resistance of high strength and plastic back-up rings. Guiding rings are not exposed to radial forces and this is very important for long lifetime. It leads to minimal friction, which also have positive effect the lifetime. _x000D_
