Abstract
A coupling including a first member having a first body portion with threads tapered at a less than standard taper rate extending along an exterior surface thereof and a first flange portion extending therefrom. A first recess extends axially into the first flange portion and a first seal is located within the first recess. A body flange portion extends from the first body portion and axially spaced apart therefrom. A second recess extends axially into the first body flange portion and a second sealing ring is located within the second recess. The second seal is identical in size and shape with the first seal and is interchangeable therewith.
Claims19
A coupling comprising:
- a first tubular member having a first body portion with threads tapered at a taper rate of less than 1 inch of diameter in 16 inches of length extending at least partially along an exterior surface portion thereof;
- a first flange end portion extending radially outwardly from the first body portion;
- a first recess extending axially into the first flange end portion parallel relative a longitudinal axis of the first tubular member and toward the first body portion;
- a first sealing ring within the first recess;
- a first body flange portion extending radially outwardly from the first body portion and axially spaced apart from the first flange end portion;
- a second recess extending axially into the first body flange portion parallel relative the longitudinal axis of the first tubular member and toward the first flange end portion;
- and,
- a second sealing ring within the second recess;
- wherein the second sealing ring is identical in size and shape with the first sealing ring and is interchangeable with the first sealing ring.
