How do you remove the metal O ring off a Jensen safety valve? I am trying to make the spring tougher for higher PSI.
I can not get that thing off. I’ve twisted and pulled it.
Please look closely at the end of the shaft where the spring washer is retained. Use a magnifying glass if needed. You will see that the shaft is "upset", that is pinched to make it swell in one direction so that the washer and spring are permanently captured.
You will need to use either pliers (I like Vise Grips for this) or better yet a vise, to pinch the bulges on the end of the shaft IN until the washer and spring have clearance to be removed. If that doesn't work for you perhaps you could file the excess material away, but then you are short material to reassemble, which is still okay if you plan to thread the end of the shaft so you can use a nut to retain the spring and washer.
If not planning to thread and use a nut, after you have installed a replacement spring, or two, then replace the washer and either pinch the shaft until it is fat enough to retain the washer or peen it with a hammer and blunt chisel or punch.
Hope that helps!

This worked, thanks. Boiler is running at 25-30psi. Just stretched the spring out after removal of that O ring.
May I ask how you accomplished all of that and got the boiler up to pressure to see that it worked in the three minutes that elapsed between our two posts?
I'd certainly love to learn how to be able to expand time like that, could get lots more done in this life!!! ;c)

I had solved the issue before your post but wanted to grant you credit anyways. LOL!
I removed the O ring by forcing it with pliers.

Here is a 11 second short of the whistle @ 30psi.

My go to for finagling the S/V.
Cut a short piece, perhaps 3/16", of copper or brass tubing
whose inner diameter is larger than the S/V shaft. Then,
slit it down one side. Open it a bit to slip over the S/V
shaft, hold the spring back with one hand, slip it over and
clamp it shut. Doesn't have to be fancy. It will get more
oomph out of your boiler. I know they have been tested to
much more, so the 25lbs+ I get are safe - so long as the rest
of the steam plant is sound.
