R-503

[DaleP]

Has anyone got a good source for R-503? I have a situation where I still need to use it so I can't switch to 95 or the like. Thanks for the help. DaleP

Retro it to 508, or if customer too cheap to r23, or if still too cheap, get new customer

Or if still too cheap, retro them to using dry ice instead!

What is 508???? Do u mean 408??? If so I dont think 408 will come close to 503. What is R-23??? do u mean R-123?? If so that is a replacemet for R-11.

R508B, also known as DuPont's SUVA 95, is a long term replacement for R13, R503 and R23.

If I had POE in the system I would have changed it out in a heart beat. Not that lucky this time. Thanks for all the input. DaleP

if this topic is still open for discussion iam able to sell you a 100lb torpedo of r503. It would be pretty cheap per pound.

Last month I bought a 100lb cyl of r13b1, care to guess the price.

actually POE and 508 are not a match made in duponts heaven. Sanyo uses 508 with AB 150TD in the -86c cascades and I think everything else they run 508 in without any issues. I found POE to cause me more problems below the -80 mark than anything else. What oil do you have to work with?

I haven't even tried poe in ultra-low apps, and I haven't had any issues w/ 508b and zerol 150, but I still use 290 to make it sticky.(more miscible)
