Model: 14brush - $3.25
I had these 20" long brushes custom manufactured specifically for cleaning the inside of the sight glass kits offered here. The overall length is 20" and has a 1/2" loop on the end to hold onto. The brush part is 1/4" diameter by 1" long and uses a very soft nylon that will not scratch the tubing when used with water or your favorite kettle cleaning solution.
This works great when a simple soaking just doesn't cut it. I do NOT have a discounted shipping method on this so I highly recommend that you only add this to the cart if you're already purchasing a kit or other accessory that justifies the shipping. If adding this to an order for items that ship in smaller boxes, I will slightly bend the handle to fit. You can straighten it with no problem.
