Fig. 7042
Outlet Coupling
The Gruvlok Fig. 7042 Outlet Coupling is designed to join two
sections of grooved end pipe and form a reducing outlet
connection. The outlet couplings are available for the 1 1/2"
through 6" IPS or ISO run pipe sizes with the outlet pipe sizes
ranging from 1/2" through 2".
Assembly of the coupling will create a gap between the pipe
ends allowing the space required for the introduction of an
outlet connection. The outlet connections are available
grooved (Fig. 7042G), FPT (Fig. 7042F) and MPT (Fig. 7042M).
The gaskets are available in EPDM and Nitrile to suit a wide
range of applications. The gasket design is a unique pressure
responsive design that provides a higher sealing force as
pressure is increased. The outlet gasket seal is reinforced by a
steel ring and is mated to a machined housing surface to
assure a leak-tight outlet seal. Center ribs inside the gasket
ease positioning of the pipe during installation and provide
additional support to the gasket. The outlet couplings
are NOT recommended for vacuum applications or for use
with the Gruvlok Advanced Copper Method.
