The BM regulator (bit that goes into the tank and has the the outlets and gauges) on my ryobi compressor was leaking and in trying to get it off to replace I’ve snapped it at the tank. See attached pic...
Any ideas how I’d remove the remaining piece ? I stupidly assumed it would just unscrew but a friend suggested it may have had a thread locker liquid applied in the factory. The spare parts manual says the BM reg is unavailable, does this mean it’s not supposed to be removed ?
many thanks, Sam
eBay has plenty of options to replace that (once you get the last bit out :))

I believe a lot of heat will soften thread sealant, so that may work with an easyout. Good luck with it.
A bit hard to see from the pic, but can you get an ezi-out in there to unscrew the remaining piece ? A bit of heat from an oxy or mapp torch will soften the loctite.
The OEM may have used epoxy as a thread sealant, seen it done many times. Where a manufacturer requires specific components to align in specific directions but chooses to use cheap-arsed tapered threads getting a decent seal with standard thread sealants is tricky, so a cheap epoxy is used which will allow the components to be positioned in any orientation and still provide an air-tight seal regardless of how many threads are engaged.
The thread will likely be a 3/8” BSPT, if the easy-out doesn’t work I’d be smashing as much of the zinc out of the hole as I could and gently running a tap down it to cut out the rest.
If the inner piece won't come out you could leave it and cut a thread on the outside to take a socket reducer to suit the regulator.
:o Being a pressure vessel I would be very cautious in taking this approach. :no: In fact I would not do it!Quote:

Thanks for the replies. I have a replacement regulator on the way. Will try heat first if I can find something cheap then investigate taping the remaining piece to remove it.
I had exactly that with my Ryobi too, gentle heat softens the sealant and then I used a large flat screwdriver gently tapped in to turn it out.
I sourced some nice brass fittings locally and a brass manifold. The ebay ones can be some dodgy pot metal. MAKE SURE you set the regulator to the right pressure, and you use the pressure relief valve. From the factory the regulators are not quite right, so the first time you fire it up, watch it carefully and adjust. I took the opp to add a T so I have two take offs.
Success ! A few minutes with the hair dryer on it while clamped to my bench and it softened up to enable drilling out, lost a bit of thread but hopefully I have enough.
Thank you for your relies, in particular David.
ps - i’d appreciate if no one mentions my use of the hair dryer to my wife or daughters:)
I am absolutely shocked that a hair dryer gave enough heat to do the job?
Rgds,
Crocy.
I was surprised the whole thing worked too and wished I tried the heat before I broke the rest of it off !
Says a lot! Either crap thread sealant / Loctite or stand well back when Sam's missus grabs the hair dryer! It must be a "Q" special.Quote:
