5500-PPB-X18 Polypropylene ConeJet Adjustable Spray Tip.
The 5500 adjustable ConeJet tip is also available in a polypropylene version. The polypropylene tip has the same characteristics as the brass tip and provides excellent chemical resistance. This tip's light weight makes it well-suited for use on handheld and backpack type sprayers.
It works great for compressed air sprayers. I use them for spraying apple trees up to 10 feet tall and grapes. They are also great for **** spraying as *** can be adjusted for coarse spray applications
