FoodSaver Vacuum Sealer Kit - Plastic Jar Sealer with Accessory Hose for Regular & Wide Mouth Mason Jars | Airtight Food Storage Solution for Kitchen, Pantry & Meal Prep

This vacuum attachment in combination with my FoodSaver V2244 with as intended with practice and when following a few hints below.This item is well designed with 'U' shaped seals and the caps are solidly build of injection molded plastic. The clear hose is the perfect length snd the nipples fit perfectly into the auxiliary port on the FoodSaver and in thr caps. I recommend this item.1. The seals don't work on canning jars with large edge. See image: the jar on the left has a narrow edge below the threads and works well. The one on the right has an edge that protrudes ~0.25" and the attachment cannot make a seal on this type.2. After the air is sucked out and the vacuum finishes it's cycle, gently twist the hose end off the cap to let the sealing ring seat properly.3. When removing the vacuum cap, gently twist it or the seal may get pulled out of the cap. This is especially true for the smaller cap.
