Self-Centring Bonded Washers
Bonded washers are used in various join types and provide a high pressure seal.  The interior of the washer features a bonded material (normally a rubber compound) that compresses under tension from a bolt as it is tightened.  They are used in various hydraulic applications and effectively seal bolt joints while also preventing leaks.

Self-centring bonded washers feature an internal flange that avoids offset positioning and simplifies installation.
