1.3 or 1.4 Needle Questions

I'm considering buying a Sata, either 5000RP or 5500RP. Everything SPI says is generally 1.4 needle, but I feel like a lot of people use a 1.3

If I purchase a 1.4, can I just turn in the fluid needle if I find it is too much? Or is there some other large difference that happens other than fluid flow from 1.3 to 1.4?
 
Personally I would go with the 1.3. I own a 1.3 and have a 1.2 needle/nozzle set for it that I use in some instances. Sata's needle's are oversize compared to other guns. 1.3 measures more like 1.5. 1.4 is a real hoser and not really neccesary. Yes you could turn it down but it won't spray clear quite as nicely as the 1.3. Personally for a clear gun I don't think the 1.4 is necessary as 1.3 is more than enough for overalls and works great for single or multi panel jobs as well. Also if you decide you want one or the other you can always get a needle/nozzle set and then you'll have a 1.4 or 1.3. last needle nozzle set I got for my 5000 I got on ebay for $173.00.
 
I did have the 1.2 for Sata 5000rp and used it for a couple of jobs but I did find that I had to slow down more than I wanted, The 1.3 is all you need for clear.
 
my 5000rp has a 1.9 in it. lol. had to special order the gun in that size since no one stocked anything in that size.
 
I should ask, everyone here is using the RP for clear, correct?
My 5000RP is for clear (SPI) only and the 1.3 puts out plenty.I have to pinch it down on smaller things like MC tin. Can run the fluid more open on larger areas. I don't know anything about the 5500's.
 
Are you using that for clear? Or is that for primer?

a waterborne clear and single stage. the 1.3-1.4 that we are used to on the automotive side has an equivalent of a 1.8-1.9 in wood finish/architectural coatings. a 1.8-1.9 is your typical nozzle size for that stuff. the paints only tend to be slightly thicker but generally you are talking about just getting a larger amount of material on alot more sq footage of surface.
 
I'm getting ready to go out and shoot my clear TODAY and just noticed the tech sheet says to NEVER use a 1.3 tip. I only have 1.3 and 1.8 tips. It's a DeVilbiss Starting Line gun. Would I be better off with the 1.8?
 
Hi Joe. I am in the same boat as you and have a 1.3 and 1.5 tips with a DeVilbiss Finish Line FLG-4. I asked on here and Barry said that the 1.3 would be fine for my gun specifically. I know this doesn't truly answer your question, but my guess is you'll be fine with the 1.3 tip (as opposed to the 1.8).

Good luck,
Chris

Text Barry on the Tech Line to be sure. I have no experience with that gun so I can't tell you anything. Only thing I can tell you is that most guns other than Sata RP's like the 1.4 needle/nozzle size. The Sata RP's do well with a 1.3.
