Fitting with draw mechanism

摘要

A fitting includes a hollow body, a sealing member, and a draw mechanism. The fitting mechanism includes a primary actuation element coupled with the body at a first end, and a plurality of secondary actuation elements coupled to the sealing member. The plurality of secondary actuation elements are positioned in an interior of the hollow body and circumferentially spaced from each other. The plurality of secondary actuation elements are also engaged with the primary actuation element such that actuation of the primary actuation element draws the plurality of secondary actuation elements axially towards the opening at the first end of the hollow body thereby translating the sealing member from an open position to a sealing position.
