Pipe fitting with draw mechanism

A fitting, comprising:

• a hollow main body having a distal end;
• a gasket positioned on an interior surface of the hollow main body, the gasket having a length aligned with a central longitudinal axis of the hollow main body and a cross-sectional shape configured such that the gasket engages with the interior surface of the hollow main body along a distance less than the length of the gasket, wherein the cross-sectional shape of the gasket includes:
• a first, radially inner-most side that extends parallel to the central longitudinal axis of the hollow main body;
• a second, longitudinally-outward facing side that extends perpendicular to the first side;
• a third, longitudinally-inward facing side that extends perpendicular to the first side;
• a fourth side that extends from the second side to a location midway between a plane of the second side and a plane of the third side, wherein a first angle between the fourth side and the second side is greater than ninety degrees;
• and
• a fifth side that extends from the third side to meet the fourth side at the location midway between the plane of the second side and the plane of the third side, wherein a second angle between the fifth side and the third side is greater than ninety degrees;
• and
• an actuation mechanism coupled to the gasket such that actuation of the actuation mechanism draws the gasket axially toward the distal end of the hollow main body with respect to the central longitudinal axis of the hollow main body and radially inward with respect to the central longitudinal axis of the hollow main body, thereby forcing the gasket into a sealing configuration.

A fitting, comprising:

• a hollow main body having a distal end, the distal end including a flange;
• a seal positioned on an interior surface of the hollow main body;
• and
• an actuation mechanism coupled to an exterior surface of the hollow main body, wherein the exterior surface of the hollow main body extends from a distal side of the flange and at an oblique angle with respect to the interior surface and to the flange;
• wherein actuation of the actuation mechanism draws the seal axially toward the distal end of the hollow main body with respect to the central longitudinal axis of the hollow main body and radially inward with respect to the central longitudinal axis of the hollow main body, thereby forcing the seal into a sealing configuration.
