FREQUENTLY ASKED QUESTIONS


HOW DO I.....

Question: How do I remove a previously installed Nozzle Tip?

Answer: Over time, the Nozzle Tips can become seized into the Nozzle body. The best way to remove them is to use heat. Using an external heat source, gradually heat the lower part of the Nozzle body, particularly where the threads are located. Once the area is heated, use correct socket and wrench to loosen the tip. **Note: In some applications, you will be able to remove the body heater. If you are able to slide the heater(s) over the tip, it is recommended that you do so.

EXTERNALHEAT SOURCE

**NOTE: THIS VIEW SHOWS A NOZZLE ASSEMBLY WHERE THE HEATER IS UNABLE TO SLIDE OVER THE NOZZLE TIP.
