No Cleaner Needed: Improved foam gun equipped with valve. After using the foam gun, just turn the valve and push out the rest of the foam rather than using a cleaner. Therefore, you do not need to purchase a clean solution separately. Save Money. Convenient to Use: The spring-loaded trigger and control knob allow you to precisely control the flow and adjust the spray distance, avoiding wasted foam. Copper tips make the flow smooth. Ergonomic Design: The foam gun is coated with polytetra fluoroethylene (PTFE) which can keep the gun clean and durable. The handle is made of ergonomic ABS plastic which is comfortable for long-term use. Widely uses: high extension, small shrinkage, strong grip, suitable for balcony doors and windows, bathtub and air conditioning hole. Ideal for filling, sealing and insulating small spaces.
