♠Description-Hydraulic PU material U2 Rod Seal | Rod Rings IDI UHS UN U2 Cup Seal
U2 Rod Seal is the result of further development. It has two sealing lips and a strong anti-extrusion retaining ring. This additional lubrication is maintained in the sealing gap due to the action of the two sealing lips. (This greatly reduces dry friction and wear, thus extending the life of the seal.)
Under certain conditions, satisfactory sealing performance can only be achieved by means of seals installed in their respective grooves one after the other. U2, a two-channel lip seal, can replace the expensive series device. Above all, U2 Rod Seal can be used in a variety of applications where the physical properties of ordinary rubber or fabric reinforced rubber are not met.
