RRR 221

PRODUCT DESCRIPTION

The PRR221 profile ring is used as static seal, often as an alternative to an O-ring/backup ring combination. Furthermore, problems relating to the torsion of the sealing element are eliminated. In addition, the PRR221 is not susceptible to gap extrusion, pressure

 

PRODUCT ADVANTAGES

  • Low mechanical deformation of the cross-section under pressure loads
  • No torsion of the seals in the groove
  • Easy handling during installation
  • Low susceptibility to gap extrusion
  • No relative movement in the grove during pressure pulsation
  • Low leakage even with low viscosity media
  • Minimal cross-section deformation
  • One seal replaces O-Ring/backup ring
