ASTON OR O-RING

    OR O-Rings
    O-Rings were developed for use as a seal static (preferably) or dynamic in locations rectangular. They are energized by pressure and they can work as a simple seal or double effect. The radial loads, which guarantee a good seal, increase with pressure. Thanks to their elasticity, they can be installed easily and in a short time without the use of special accessories. The material used is a nitrile rubber a low permanent deformation with hardness 70 °, particularly used in production of hydraulic seals.
