No Cleaner NeededUpgraded foam gun equipped with valve. After using the foam gun, just twist 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. Wide Uses: High expansion, small shrinkage, strong adhesion, suitable for balcony doors and windows, bathtub and air conditioning hole. Ideal for filling, sealing and insulating small spaces. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
