HFT® has lots of enquiries for special stoppers, some of which we are able to manufacture.
Here’s a picture of one based on the QuickPurge®II System, which we were able to manufacture easily.
For want of a better term, we call this a “Pancake” stopper.
As you can see, it is 24” diameter and it is made to be resistant to triethylene glycol.
We manufacture the inflatable, aluminium and steel stoppers up to 80” diameter.
