In mechanical engineering, a bonded seal is a type of washer used to provide a seal around a screw or bolt. Originally made by Dowty Group, they are also known as Dowty seals or Dowty washers. [ 1 ] Now widely manufactured, they are available in a range of standard sizes and materials [ 2 ] [ 3 ] [ 4 ]
The sealing of the Parflange F37 retaining ring connection is done by a bonded seal on the face side of the pipe end or alternatively by a pipe seal carrier ("PSC"). The pipe seal carrier has soft seales (o-rings or F37-Seals) on both sides. On one side, the pipe seal carrier has a centering aid to improve assembly.
Category 2 seal are intended for API-610 This category is applicable for temperatures between –40 °F and 750 °F (-40 °C and 400 °C) and pressures to 615 PSI (42 bar). Category 3 seals are essentially the original seals of 1st Edition and are also intended for API-610 pumps. Category 3 seals are intended for the most demanding applications.
A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .

Compared to glass frit bonding, the advantage sticks out that the reduction of seal ring geometries, an increase of the hermeticity levels and a shrinking of device size is possible. The geometry of eutectic seals is characterized by a thickness of 1 - 5 μm and a wideness of > 50 μm.
