What is the purpose of the notch in a coupler???

now that's one thing I haven't figured out yet. But, I quit using them. I just drop the tip in disposable anymore. I'm lazy.....

good question, but I don't know the answer either.

Ooh Ooh I know, I know.....it's because there are certain tips that have a little metal arm thingy inside of them and they won't go on a coupler with no notch cut out!!

it's the drop flower tips ( I just looked at my tips) #224 has one of those little metal things in it.

Oh I seeeeee......
Thank you!!!!

Well.... who knew? I've always wondered myself!

wow now I know, was also wondering the same thing

Cool- I learn something new everyday!

Basically couplers are for when you are doing different techniques with different tips with the same bag. That way
you only change the tip and dont have to make a bag for every tip you need.
