G-9 The Grey Chemical Sprayer is a industry favorite among detail professionals everywhere. Strong enough to use all your normal heavy duty cleaners or acid base products like Walt's Wire Wheel Cleaner or HD Degreaser. This Chemical resistant sprayer is built tough with high end O rings and pistons for a longer more durable sprayer. Made for a high output spray to help reduce wear on the sprayer from over using the sprayer pump & piston cup. Designed with a 80/400 thread to fit on our 16oz & 32oz Bee Hive Spray Bottles. Note: After each use rinse the sprayer out with fresh water. Flushing all the left over chemicals out of your spray will help assure you get the max life out of your chemical sprayer.
