Immersion-Well Adapter Question (pic)

My old residential oil boiler had the following immersion well adapter/extender on it:

As you can see, in order to remove the control from the adapter, I had to cut the sensing bulb's copper wire "capillary". That's because the bulb itself would not and will not budge from the adapter. I've whacked it with a hammer several times to no avail.

So I'm wondering now if maybe the bulb is attached to the adapter as part of its design? Or am I just dealing with a typical stuck bulb? I've heard about bulbs getting stuck in wells as a result of heat transfer paste drying out...

If I can remove the bulb, then I'll keep the adapter on the shelf. Otherwise, it's going right into my pail of copper scrap.

Thanks.

Have you tried any solvent yet? I would first try some PB Blaster... prop it up and put a teaspoon or so into it. Let it sit for a week or so... try some heat after that.

What aquastat was attached?

Good idea Troop. I'll squirt it down with some PB Blaster and then try again in a week or two.

The adapter was attached to a Honeywell L8024A.
