I found a great site, [link=http://www.smallparts.com]Small Parts[/link], which has all sorts of parts including squeeze bottles, syringes, needles, taper tips, and even flexible teflon needles in guages of 14, 20, and 24. Blurb from the site follows.

Anyone have recommendations as to the approriate needle size for white glue, alphatic glue, and the varioius CA glue types?

Thanks,

Teflon Disposable Needles
Fluid Dispensing, H.D Polyethelene Luer Hub
For dispensation of material into hard to get areas, flexible Teflon Needles are most convenient. They also allow dispensing of cyanoacrylates and other bonding materials without premature clogging. Teflon needles will not scratch or mar highly sensitive surfaces. The plastic Luer lock hub enables full compatibility with Luer Lock Syringes and squeeze bottles. Body is molded plastic. Needle length is 2".
