Fittings for Poly and Vinyl Tubing
All our fittings listed in a size will work with any tubing listed in the same size!
Fittings can be confusing with all the different sizes of tubing, then add in that if you bought tubing at a local store they may only call it 1/2" but give you no I.D. or O.D. for getting the correct fittings elsewhere. We can't tell you what you got someplace else but here is what you need to know for our tubing sizes!
All fittings have an I.D. or O.D. listed that they work with. Match this up with your tubing size and you're good to go!
I.D. = Inside Diameter
O.D. = Outside Diameter.
