All the Advantages of the
DODGE® PARA-FLEX® Couplings
— Now in a Smaller, More
Powerful, and Cost-Effective
Package
DODGE proudly introduces the
newest and most technologically
advanced products in our DODGE
coupling line—the new DODGE
PARA-FLEX GTL and GT couplings.
These unique new couplings combine
all the advantages of our standard
PARA-FLEX coupling—dependable
performance, high misalignment,
and less maintenance—with the
added benefits of a smaller, more
cost-effective and easier to install
coupling.
With larger bore sizes and higher
torque ratings, PARA-FLEX GTL and
GT couplings let you reduce your
inventory substantially. Plus, the
PARA-FLEX GT features our patented
GRIP TIGHT® keyless bushing
PARA-FLEX PXGTL
with TAPER-LOCK® Bushing
PARA-FLEX PXGT
with GRIP TIGHT Bushing
technology. Exclusive to the DODGE
brand, it limits vibrations by providing
360° concentric contact with the
shaft.
No other couplings can offer you the
same outstanding misalignment and
vibration handling capabilities as well
as fast, easy element installation on
misaligned shafts, as the new PARA-
FLEX GTL and GT couplings. With
their “problem solver” element, they
are not only the industry’s leading
combined angular, parallel, and axial
misalignment coupling, but they are
the only coupling in the industry with
a five-year element warranty.

Element Locking Nut w/ Micro-Mount
Bolts - provides fast element installation &
replacement,
External Clamp Ring – Micro-Mount bolts
push the face of the external clamp ring which
applies holding pressure to the element
GTL Flange – Accepts a larger size TL Bushing
than traditional PXTL flange. Available in both
type F and H flanges
TL Bushing – provides broad range of bore
sizes, which reduces flange inventory & prevents
shaft damage & fretting corrosion
PARA-FLEX Element – Dampens vibrations
& shock loads, and accepts highest combined
misalignment in the industry
GRIP TIGHT Bushing – Nut – Allows for fast
mounting & dismounting of GRIP TIGHT Bushing
“Thin Wall” Adapter. Easily accessible from
the side.
GT Flange – Accepts Keyless GRIP TIGHT
Adapters
GRIP TIGHT Bushing - “Thin Wall” Adapter
– Provides largest bushed bore capability, and

PARA-FLEX GT couplings’ GRIP TIGHT thin-wall adapter and the PARA-FLEX GTL couplings’ larger
Taper-Lock bushing allows larger bore sizes to be used in smaller couplings. The new element
locking nut allows for greater torque ratings to be achieved. That means a smaller, less expensive
PARA-FLEX GTL and GT coupling has the same capabilities as a larger, more expensive coupling.

PARA-FLEX GTL and GT couplings are designed to reduce your inventory substantially because
fewer ratings cover the entire bore size range and torque ranges of today’s existing PARA-FLEX
sizes. Also, TL and GT bushings minimize the requirement of maintaining flange inventory.

PARA-FLEX GTL and GT couplings are engineered with only the highest quality
materials and are manufactured using ISO certified processes. For that reason, the
PARA-FLEX “problem solver” elements carry a pro-rated five-year warranty*—better
than any other coupling element currently on the market.

Only the PARA-FLEX “problem-solver” element offers the highest, across-the-board handling of
angular, parallel, and end-float misalignment problems. The “problem solver” among couplings, it
can accommodate virtually any application and/or unexpected process problem without having to
provide inflated service factors or a larger coupling.

which provide eccentric shaft connections
which induce vibrations.
