Drop-ear elbows provide a ½" or ¾" F NPT threaded
connection at a wall or oor penetration as well as a
ange for securing the tting.
Drop-ear bend supports allow ViegaPEX Ultra tubing to
be directly stubbed out of a wall. These supports allow
the tubing to make the tight bend necessary to exit
the wall at a 90° angle as well as providing aange for
securing the support.
The exposed tubing can then be connected to a valve,
using an optional chrome sleeve to cover the tubing if
desired.
