KBT-B type seals are intended exclusively for external sealing (piston sealing) in double-acting hydraulic cylinders. This seal types are designed of four parts, of which central is sealing element comprising of smaller inner rubber ring, and outer cotton fabric reinforced rubber ring. At each side of the centerline sealing element are polyacetal rings that protect the sealing rings from sudden pressure changes, and have guiding role for the piston.
Compact design of these seal type allow designers to construct very compact pistons. KBT-B type seals shows very high durability and allows the application in more demanding conditions than KBT-A type seals.
