QRN
Design
    • Quad Shaped Orings are useful in applications where a traditional Oring profile has failed due to spiralling. The Quad shaped profile helps to stabilise the Oring and prevent the oring from spiralling in its groove.
    • Can be combined with a backup ring to increase the pressure tolerance and assist in resisting extrusion.
    • Available in a wide variety of materials in a wide variety of sizes.
Material
    • Nitrile 70A Duro - Precision Moulded.
Application
    • Orings can be used in a wide variety of hydraulic, pneumatic and general purpose applications.
    • Whilst in certain applications an Oring can be used in a dynamic environment, it is recommended that Orings be used in a static applications only.
Fluids
    • Hydraulic fluids, petroleum fuels and oils
