Does anyone know what this is??

I could not get a better image right now
so I will try to describe it.

![URL removed]

This is a thick, clear glass radio tube looking thing.
It is 3 1/4" High (4" to top of the screw)

The screw comes through the bottom and holds a large,
weak spring inside.It has 2 nuts with a thin copper
washer(?) between them.
There is also two small wire (?) holes through the bottom.

Embossed on the front [URL removed] 500V above a UL circle, and
932K, #200.
On the reverse [URL removed] Made in USA,Heat resistant housing,
Peterson P-K,5

What looks like treads are not.
The end with the screw is the bottom.
