Abstract
Expansion seal ring with an essentially torus shaped expansion seal (1) which is provided between two concentric positionable connection pieces (2, 3) to be sealed or the like, which include a sealing section (1a) which is pulled over the edge (3a) of one of the two connection pieces (3), and which includes an expandable section (1b), which is provided to be radially effective between the two connection pieces (2, 3), as well as a jacket (4) which essentially completely covers or envelopes the expansion seal (1) at least in the area of the expandable section (1b).

Expansion seal ring for sealing between two concentric positionable connectors (2, 3) each having a rim defining an opening (2a, 3a), said expansion seal ring comprising:
- an essentially torus shaped expansion seal (1) dimensioned for introduction between first and second concentric positionable connectors (2,3) to be sealed, said expansion seal (1) including an expansion seal radially outer sealing lip (1a) dimensioned and adapted to be drawn over and seated on said rim (3a) of said first connector (3), which said expansion seal (1) includes a radially expandable section (1b), and
- a jacket adapted to essentially completely envelope the expansion seal (1) at least in the area of the expansion seal radially expandable section (1b).
Expansion seal ring for sealing between two concentric positionable connectors (2, 3), said expansion seal ring comprising:
- an expansion seal (1) including
- (a) an essentially torus shaped radially expandable section, and
- (b) an expansion seal radially outer sealing lip (1a) defining a recess between said lip and said radially expandable section, and
- a jacket (4) covering at least the radially expandable section (1b) of the expansion seal (1).
Process providing an expansion seal capable of sealing between a first and a second concentric positionable connectors (2, 3) each of which having a rim defining an opening, and comprising:
- (a) obtaining an annular ring shaped jacket (4) having an outer edge and an inner edge;
- (b) tensioning the outer edge of the jacket (4) over the rim (3a) of said first connector (3),
- (c) obtaining an expansion seal (1) including an essentially torus shaped radially expandable section (1b) and an expansion seal radially outer sealing lip (1a), said expansion seal (1) having a recess defined between said lip and said radially expandable section, said recess dimensioned for engagement with said rim (3a) of said first connector (3),
- (d) seating said expansion seal (1) such that said tensioned outer edge of said jacket (4) and said rim (3a) of said first connector (3) are introduced into said expansion seal recess, and
- (e) drawing said inner edge (4b) of said jacket (4) outwardly over the expansion seal (1) and over the connector rim (3a) to essentially completely envelope the expansion seal (1) at least in the area of the radially expandable section (1b).
