GLASSLINED TANK FEATURES

“Glasslining,” a porcelain protective coating to a steel tank interior,
is the plumbing industry’s most time-tested system for protection of
tanks. A. O. Smith Glasslined Pump Tanks feature rolled-steel
construction, and every A. O. Smith Tank is made in the U.S.A.

Other A. O. Smith features include a 1-1/4˝ NPT spud on top for
motor mount or retention tank connections, a 1/4˝ switch or gauge
tapping on the air side of the tank, and full-size 1-1/4˝ connections
at all needed locations.
