I have the McMaster Carr seals and really like the look and mostly like their function. I don't recall it being that much extra work. However, my only complaint is with getting them to stay in place. I want them to be removable in the future for replacement, but they need to stick in place better. I've squeezed the grip until it's tight, but they still pull off easily if they are inadvertently grabbed, which happens often. Has anyone used an adhesive that holds well but allows future removal if necessary?
