What is a good gauge to use primo with.
What is a good gauge to use primo with.
depends on the manufacturer ( dont post it if its a ugl) and how thick there oil is. most use a 23-25 guage pin
thanks...
I use 25 guage but it takes 4 ever. It seem like the oil is to thick
23 guage is fine
could even use a 18g pin to withdraw it faster .
note that you dont wanna use the 18 guage to inject with though.
23g is my favorite personally
