1. A flowline connector assembly comprising: a first flowline member having an annular configuration defining a first passageway, wherein the first passageway includes a first seat that extends in a direction that is substantially perpendicular to an axis of the flowline connector assembly, and wherein the first flowline member includes a first stop extending radially outward from an outer surface of the first flowline member; a second flowline member having an annular configuration defining a second passageway, wherein the second passageway includes a second seat that extends in a direction that is substantially perpendicular to the axis; a pin having a first end, a second end, and a substantially cylindrical outer surface extending therebetween, wherein the pin is configured to be inserted into the first passageway and the second passageway such that the pin is radially aligned with the first passageway and the second passageway and such that at least one of the first end contacts the first seat, or the second end contacts the second seat, wherein the substantially cylindrical outer surface of the pin includes: a first portion proximate the first end, a second portion comprising a tapered surface, a third portion, wherein the second portion is between the first portion and the third portion, and a fourth portion, wherein the third portion is between the second portion and the fourth portion, wherein a diameter of the fourth portion is less than a diameter of the third portion, wherein an inner surface of the first flowline member contacts the first, second, and third portions of the substantially cylindrical outer surface of the pin, and wherein an inner surface of the second flowline member contacts the fourth portion of the substantially cylindrical outer surface of the pin, wherein an inner diameter of the first end and the second end are substantially the same, wherein an outer diameter of the first end is different than an outer diameter of the second end, such that a thickness of the first end is different than a thickness of the second end; and a collar having a first inner diameter at a first end of the collar and at a second end of the collar, and a second inner diameter at a middle portion of the collar, wherein the first inner diameter is less than the second inner diameter, wherein an inner surface of the collar at the first end of the collar is configured to contact a first side of the first stop, and wherein the inner surface of the collar at the second end of the collar is configured to contact a first side of a second stop to connect the first flowline member with the second flowline member.
