stuck insert in provalve

[mjones78]

any recommendations for a stuck insert in a provalve?

Yes. Never use lubrication and never take them out and they will get stuck!

I assume by now the hex is shredded?

appropriate sized allen key, dead blow hammer. Hit the allen key with said hammer but to tighten it not to loosen. This is likely to break the threads loose and then it should come out. If not, then lay the tank down, valve facing up. Pour some hot vinegar slowly around the threads and let it sit for about 5 minutes and repeat making sure to rinse thoroughly once it comes out to prevent damage to the chrome

If you truly can't get it out - buy another valve before destroying yours. You can purchase a DGX Pro Valve for $39 DGX Premium Pro Valve, Right (Typical Side) | Dive Gear Express®

Are you saying to lubricate the threads and periodically remove the insert to prevent it getting stuck?

High force should be a last resort. You can use hot and cold to open the gaps in the threads and allow solvents in. Combine that with ultrasonic cleaner baths and you might get lucky. When you are ready to throw in the towel, try a hand impact wrench (with an easy out if the hex ftting is unusable).

$39 through DGX, and enjoy your yoke valve....

Is it stripped? If not, use valve grinding compound (Clover) on the hex key, it will greatly increase the grip. Unfortunately, once the insert strips (the hex) you are left with more brute force methods like screw removers (the ones from Snapon work best) or removing the valve, putting it in a drill press and drilling it out. Then use a punch to tap the edges of the remaining insert to break it free and remove what is left.

If you have a small impact hammer or hammer drill/driver, might help. I would use the aforementioned Clover on the hex bit.

I am not gloating here but I like that in another concurrent thread one poster essentially denied such things happen as part of the usual DIN glorification fanfare. I have better things to do that R&R DIN inserts often enough to prevent corrosion and seizing.

I take all of my inserts out until I need it in place and then I take it out after the dive and hang it up on the valve in a small piece of tight mesh so it doesn't get lost. In 4 years I've not had one get stuck.
