First purchase CLOSURE SET includes nozzle holder end closure, delay holder end closure, liner ejector dowel, spare o-rings, instructions. All other parts are separate components for replacement or special applications. Nozzle closure has positive seal in two places and recommended nozzle (included in reload packs) is reuseable at least three times. Bulkhead closure has positive seal in one place and standard friction fit delay element. Closure accepts small quantities of ejection powder in the well and 1/8g is recommended for MR. In particular the nozzle o-ring can be damaged by installation of nozzles so bevel the nozzle edge slightly with sandpaper to increase seal life.
