GDKK Combination Seal

The GDKK Combination Seal consists of a sealing ring, two guide rings, two retaining rings, and an elastic rubber ring. The guide rings provide positioning and guidance, the retaining rings offer support and positioning, and the elastic rubber ring provides pre-compression while compensating for wear on the sealing ring. The sealing ring forms a seal with the cylinder bore to create a sealing effect. The GDKK seal offers bidirectional sealing.
