PowrTex part 600-066 is a replacement nozzle nut used to secure spray tips to the gun or spray wand on compatible PowrTex diaphragm sprayers. The nut threads onto the spray tip housing, holding the tip firmly in place during operation and allowing quick tip changes without tools.

The PowrTex 600-066 Nozzle Nut is a direct replacement for the original tip‑retaining nut used on PowrTex 300dd and 600dd sprayers. This component threads onto the spray gun or wand tip housing to secure the spray tip during high‑pressure operation.
A cracked, stripped, or missing nozzle nut will prevent the spray tip from sealing properly, leading to leaks, uneven spray patterns, or the tip blowing off under pressure. Replacing the nut restores a secure fit and allows quick tip changes without special tools.

When replacing the nozzle nut, inspect these associated components for wear or damage.
Worn or damaged tips can cause poor atomization. Replace if the spray pattern is uneven.
Cracked housing or damaged sealing surface will cause leaks even with a new nut.
The sealing ring between tip and housing can harden or flatten, causing leaks.
