DUBO Retaining Ring

  Multiple locking and sealing because DUBO Retaining Rings:

• flow into the threads of the bolt and the nut;
• create a particularly effective frictional resistance with the bolt and thereby;
• prevent rotation of the retaining ring around the bolt;
• wrapround the flats on the nut and thereby effectively prevent the nut from loosening;
• by filling all free spaces, seal against leakage.

  Sound-deadening properties and durability because DUBO Retaining Rings:

• absorb vibrations arising in any bolt assembly;
• have plastic-flexible characteristics;
• neither deteriorate nor wear, and therefore can always be re-used again and again without loss of the above-mentioned advantages.

• are chemically resistant to Alkalis, to solutions of neutral inorganic salts, to oils, fats, petrol, benzine, alcohol, acetone, diluted acids, and sea water;
• prevent electrolytic corrosion between two different metal surfaces;
• prevent fatigue in the bolt material.
