BONDED SEAL was originally designed to withstand high pressures, and it
Is being substituted for copper type washers in higher pressure system. The XLONG Bonded
Seal comprises a metal washer and an elastomeric ring bonded inside the diameter. The metal
Washer prevents over-compression and limits deformation of the elastomeric ring; The elastomer
Prevents lubricant leakage internally and avoids water or the pollutant invasion from outside
Environment.
