ASTON SGA ROD SEAL

    SGA ROD SEAL
    – A sealing element in nitrile rubber with low permanent deformation which ensures excellent sealing capacity. Multiple sealing lips ensure a perfect fluid control and concentrate the load against the dynamic surface. The cavity between the sealing lips hold a small amount of fluid that reduces friction and wear.
    – A support ring that fits the shape of the sealing element. The special “V” shape guarantees its energization when it is subjected to heavy loads of pressure. – An anti-extrusion ring that protects the gasket when subjected to high pressures.
