cocktail sticks -bamboo skewers o r some times you can squeeze the sides so the top lifts to roll it out but that depends on tightness in groove and hardness
Hi all, hope this is the right place. I am rebuilding a regulator, have all the 'O' rings and bits no problem but there are 'O' rings that sit in grooves in very highly finished brass parts, the question is how can I remove the rings without causing Any damage to the brass.
I have some picks but they look, when under a glass, like blunt screwdrivers.
Thank you.
Cheers.
Geoff.

try those fine point plastic toothpicks, the ones with a y shape at the other end with dental floss on, failing that use a fine sewing needle point to prick into the o-ring(but not touch the metal)
Squeeze and push forward, and wooden tooth picks.

Give them a blast with the blow torch!
That wont help putting them back on though.

A barbless fishing hook clamped in a pin vice and cocktail stick should work .
Many thanks all, there is a fishing tackle shop not far away, the rings are deep in the grooves with only a tiny amount of protrusion and I cant squeeze them. Just being careful could be a very expensive slip!
Cheers.

I use a couple of large sea fishing hooks (6/0) both have been straightened a bit one has the point 2mm bent 90* to stick in to the ring, the other has been filed blunt & flat in case the ring is going to be reused.
If really tight a dab of grease wiped on the metal lip can help them slip out same as a wipe on the new O ring helps it seat.
If you have access using tweezers or needle nose pliers you can often squeeze the O ring so that a section pulls away enough to get a tool behind it.
as you have replacements cut it with a razor and just replace
obviously you need to have a steady hand and cut it like you were making a scarf joint
Stick a pin in 'em, lift 'em and use a toothpick in the gap
