Abstract
A gasket is provided that forms a sealing connection between a pair of tubular members. The gasket comprises a first section shaped to fit within a recess of one of a pair of tubular members. The first section includes an anchor portion comprising first and second sides. The gasket further comprises a second section extending from the first section and is configured to make a sealing contact with the other of the tubular members. The gasket also includes at least one self-locating arm in a sealing contact within the recess and extending from one of the first or second sides of the anchor portion of the first section. The self-locating arm biases the first section such that the other of the first or second sides is in contact with the recess to form a sealing connection.
Claims28
A gasket for forming a tubular connection between a pair of tubular members comprising:
- a first section having an anchor member comprising a continuous convex surface of a wall, at least one curvilinear self-locating arm, and a continuous concave surface of a wall, the continuous convex surface having first and second distal ends, the continuous concave surface having first and second distal ends, the first distal end of the continuous convex surface connected to the first distal end of the continuous concave surface, the at least one curvilinear self-locating arm being located between first distal ends of said continuous convex surface and said continuous concave surface, the first section being formed from a first material having a first durometer, the at least one curvilinear self-locating arm adapted to be in contact with a recess of a tubular member during use;
- a second section extending from said first section and adapted to make sealing contact between tubular members during use, the second section being formed from a second material having a second durometer, wherein said first material has a higher durometer than the second material;
- the second section comprising a sealing portion and a shoulder portion extending from the first section adapted to be outside of a recess of a tubular member during use to provide support to said second section;
- and
- the at least one curvilinear self-locating arm and the shoulder portion extend in opposite axial direction.
