Removing fittings from a really expensive valve.


Postby SpudStuff » Sun Oct 08, 2006 6:01 pm

I have a 6000 PSI (six thousand) 3 way valve i am going to use on my small hybrid. I need to remove the fittings onn the ports so i can use it. I cany seem to get them loose. I tried a ajustible wrench, a socket, and a closed end wrench. None Of these have worked( With the valve in a vice and 5 feet of pipe on the wrench as a lever). I am kinda of ticked because it broke the mechignism in my rachet. Is there a better way or is my neighbor laughing at me for a good reason. Oh yah the hey is ahout 3/16 of an inch wide.

Pictures.

This may sound stupid, but are you sure that is actually a removeable fitting? If you can't get it off with a five foot extension on a wrench, it very well could be just a hex to put a wrench on when adding a fitting to the valve. If it definitely isn't my advice would be to get a stronger wrench. If all else fails you could try heating it but you may destroy rubber seals if there are any.

EDIT - after reading this again, it doesn't seem like your wrench broke, jsut the ratchet. Maybe you just aren't strong enough? Get a really long pipe on the wrench and a few friends?

Yes the fittings are removable. The data sheet shows it with 3 1/4" FNTP ports on it.
I was using a 5 foot extenction on the wrench, I don't think it is ledverage but grip on the hex whick is very thin.

If all else fails, couldn't you take a 13/32" drill bit and ream out the inside of the nipple, then pick out the remaining pieces of the nipple?

How about using the fittings on it now and adapt from them?

Because then i would need 10mm stainless tube, two 10mm x 1/4" MNTP adapters, and two compression nuts and bushings. Thoes cost about $50 and on top of that the tube is about $ 20 because they only sell it in 60" lengths. My dad is gonna give it to the master plumbers at his work to see it they can get it off. Thoes guys get paid $120 an hour to make elaborite pnumatic and hydralic systems for testing stuff.

By the way, are you sure the valve is rated at 60,000 PSI (sixty thousand) or 6,000 (six thousand) PSI?

Oh sorry typo. It is 6000 PSI (six thousand). I also got a valve that is like 10000 PSI (ten thousand)- something like 355 torr-3. I take it that is a vaccume rating. It is Robbins Aviation. It is like a solid block of stainless. It is a needle valve and has a 1/32 orfice.

Try giving it a little heat, if they are indeed removable fittings they may have thread locker in them.
