Hey there i just got 25 nipples from QC supply. The nipples are the red ones..this is my first time using these type of nipples, what size hole do you have to drill for these nipples? Thanks Alot Truly, RIRs
I believe I read somewhere in the forums that QC supply recommends using an 11/32" bit. That is what I used and it worked perfectly- I didn't have to seal it or anything.
Are you using the type that snap into a rubber gasket or screw in. I have the snap in with the gasket and I used the recommended 11/32 bit. They are all working great!
