I am not clear on what universal fittings actually means? I keep seeing that term everywhere and when I am buying wholesale online from sites like amazon or alibaba for items like spray valves I want to make sure that they will fit on our bottles.

What do I need to know about this to make sure that I am ordering the right size, some of the listings have diameter and others just say universal fitting size. Are there some sort of connectors that I would need to connect the spray valves to, to ensure that they fit properly? Like maybe BSP or NPT, I dont even know what that sounds for? Are there standard sizes for connectors or types of connectors. I know that often times the specs are vague or inconsistient and so I guess I need to talk directly to the vendor, but what should I be asking? Buyin

I am in partnership for a nail salon and was wondering how do other people unclog spray nozzles and whether its worth the time or should we just buy a bunch of replacements. If there's an easy way to unclog them then I would rather just try that first before going to an online site like Made in China, alibaba or amazon and purchasing something that might not fit or that will not be what we want?

We have tried the shaking and hot water method, any other tactics that people know are like 100% to work please share them, because I am getting really sick of this. I think if there's thicker residue then it won't work and so I was thinking of using warm water or soaking in vinegar or alcohol to help break things down better> own a nail salon and we go through a ton of spray bottles, and the nozzles keep clogging up from product buildup. And is it worth taking the nozzle apart, or does that usually damage it?
