A locking element may temporarily hold the activator body in place and a sealing element may form a temporary seal. The activation rod may include a locking portion, a releasing portion of a smaller diameter, a sealing portion, and an unsealing portion of a smaller diameter. The locking portion may be aligned with the locking element and the sealing portion may be aligned with the sealing element when the activation rod is in the first position. The releasing portion may be aligned with the locking element and the unsealing portion may be aligned with the sealing element when the activation rod is in the second position.
