These beautiful nozzles are VERY popular and they're also VERY inexpensive too !
They're white-poly nozzles in three sizes.

I know you'll just love the look and feel of these nozzles. They have two lateral holes at the sides and one at the tip for excellent flow and have been very popular in our videos and photo sets.

The term "Barium Tip" comes from the hospital usage of these. They use them for administering "Barium" enemas during x-ray examinations of the colon. The Barium solution is a fairly thick liquid and this nozzle handles it with no problem at all !

The base of each Nozzle has a standard 5/16" Barb to fit our standard hospital-type 5/16" I.D. tubing very nicely !

Regular Small Barium Tip Approx. 5/8" Diameter X 5 1/4" Long
Regular Medium Barium Tip Approx 7/8" Diameter X 6" Long
