C-7 outlet coupling

The Model C-7 Outlet Coupling combines the features of
a coupling and a reducing outlet. The C-7 facilitates an easy
reducing branch outlet without the need of a mechanical
tee or reducing tee and couplings. The C-7 is available with
grooved, male threaded or female threaded outlets. This fitting is
recommended for fire sprinkler and other pipelines of moderate
pressure. The C-7 Outlet Coupling can be used for dry pipe
systems or vacuum services up to 10 inHg or 254 mmHg, which
may occur when the system is drained.
