"he kinda pinched the metal wand lips together in the middle"
It's not Micah, it's the wand Mfg.
If a
glide pinches your wand lips, imagine what is happening under 14"hg!
It amazes me how many wand Mfgs don't support the center of the wand.
drill a small hole in the center on the back side, just drill one side not all the way through to the front lip , drop a small 10-32 bolt into it from the backside, 3/8" or 1/2" long will be plenty, hold a nut inside the vacuum slot and thread the bolt into it, and all the way through until the screw touched the other side. viola, you are now done.
Now the glide can only compress the lips so far, and will likely fit tighter and be less prone to a leak, and every so often you can still remove the glide, screw the bolt and clean it out easily, this is much easier than a welded in pin.
We make many glides now with a machined in "bump" in the center to help keep the center of the lips apart.
