Honeywell aquastat pipe clamp

This is probably a really dumb question but how are you supposed to use this clamp?

I gave up and used a hose clamp. Twice now.

I'm sure there's something really simple I'm missing.

    That's the same style clamp as we use on TXV valve bulbs. It wraps the pipe with the tab pointing away from the pipe. Bend the other end up a little & stick the screw through a hole, then through the holes in the tab, & then thread on the nut. If there's enough length, double up the end where the screw goes through.

    It's not the easiest to get together, esp. when holding an aquastat on. Takes three or four hands, some times. I suggest you use a hose clamp. :smiley::smiley::smiley:

    Detail A, figure 8, page 7 of this PDF might clarify. Just imagine it going through the slot on the aquastat instead of around a TXV bulb.

    I usually just cut it and shape it into kind of an Omega sign.
    The hose clamp is a good idea.
