System
The fexibility designed into
the Gruvlok coupling will
accommodate misalignments
caused by imprecise location
of pipe opening through walls
and foors, will provide pitch
for drainage piping systems
and facilitate laying pipe on uneven terrain, thus permitting defection in
any direction.
The Gruvlok® piping method
Gruvlok couplings and grooved-end fttings are widely used
for joining pipe in a wide variety of piping systems. Gruvlok
couplings for grooved-end pipe are designed to provide a self-
centering joint which accommodates the application of pressure,
vacuum and other external forces, while limiting the burdensome
need for special supports, expansion joints, etc.
The Gruvlok piping method offers many mechanical design
features which beneft the design engineer, the contractor, and
the end user. Utilization of the functional characteristics of the
Gruvlok coupling will aid in pipe system design and must be
considered for proper installation, assembly and performance.
The design factors presented in the Gruvlok technical data
section should always be referenced to when designing any
grooved piping system to obtain the maximum beneft of the
Gruvlok piping method.
Gruvlok features
rigidity or flexibility
Couplings are available where rigid
connections are required. Couplings
with fexible design allow for pipe
expansion and contractions with
temperature changes. The need for an
expansion joint is minimized or
eliminated.
self restrained joint
The couplings engage the pipe
around the entire circumference and
restrain the pipe ends from separation
due to pressure and other forces, up
to the maximum coupling rated
working pressure. END

Union at every joint
Gruvlok couplings can be
disassembled easily permitting
maintenance and servicing of
the piping system. It will
facilitate periodic rotation of
pipe to distribute internal
wear from slurries or other
abrasive media.
stress-free system
Flexibility designed in the Gruvlok
coupling absorbs and eliminates stress
from settlement of buried pipe or
those induced by seismic tremors.
minimizes noise & vibration
The resilient elastomeric gasket and
pre-designed gap of the Gruvlok
coupling help isolate and absorb noise
and vibration, this minimizes vibration
transmission.
accommodates misalignment and
joint deflection
