Below is a list of Caulking Tubes manufacturers from Perris, California. Caulking tubes made of cardboard are used to dispense caulking material, which seals joints and seams in construction applications. The caulking tubes are often lined with aluminum foil or kraft paper and spiral wound to increase the holding strength of the tube. The tube is typically inserted into a caulking gun and equipped with a plastic nozzle or spout and a plastic cap at the end.
