Hot Jet S The Hot Jet S is the smallest handheld hot air tool made by Leister Technologies. The heat gun is light and easy to manoeuvre, making it a firm favourite for dozens of tasks.

The Hot Jet S is commonly used for plastic welding, speed welding, plastic tacking and melting heat shrink tubing. But for maximum versatility you need to use different nozzles for different tasks.

Nozzle attachments fix onto the heat gun and direct and manipulate hot air in different ways to get different results. 

Made from stainless steel, all the nozzles are strong and sturdy and sure to last a long time.


Hilltop Products stocks a huge variety of Leister products including the Hot Jet S and Leister accessories. Many of the Hot Jet S tools we sell are for plastic flooring specialists.

Here is our guide to the nozzles for the Leister Hot Jet S, their uses and what you will need for each job.
