Uncoated
Because some customer applications may require piping or fittings that have no coating applied to the exterior, AMERICAN furnishes, when specified at time of purchase, any of its products without exterior coatings. It is recommended that you consult with AMERICAN concerning these applications.
While AMERICAN can supply uncoated, bare pipe to meet customer specifications, it is recommended to use an asphaltic or other approved coating on the spigot when assembling a joint to reduce the probability of displacing a gasket and to reduce the overall assembly load.
