JW Couplings
Quick, Simple and Economical Pipe Coupling
Grip Ring Types
MJG
MJGL
Applications: New connections, temporary installations,
repair or partial replacement of pipework
Models & Nominal Sizes:
MJGF (20A-300A) / MJGFL (25A-300A) Pipes are held firmly
by the movement-resistant Grip-Ring on the inside of the
coupling. This recent innovation is becoming increasingly
popular as a alternative to welded, flanged and union and
groove joints. Grip-Ring joints do not require pipe edges to
be machined.
MJL
Applications: New connections, temporary installations,
repair or partial replacement of pipework
Models & Nominal Sizes:
MJS (15A-2000A) / MJL (25A-2000A) With the inside
material made of a resilient elastomer these flexible joints
absorb impact, vibration, bending up to 2~4°, noise and
thermal expansions of pipework. When using this coupling
it is recommended that pipes be constrained because the
coupling offers little axial restraint.
Flexible Types
MJS
Repair Clamp Types
Applications: Repair of Pipework
Models & Nominal Sizes:
MJR (15A-2000A) / MJRL (25A-2000A) Chiefly
used to replace damaged and leaking pipes
(holes, cracks and complete breaks). The design
of this coupling enables easy installation without
the need to split pipe.
MJR
MJRL
Hinge Clamp Types
Applications: New connections, temporary
installations, repair or partial replacement of
pipework
Models & Nominal Sizes:
MJH (15A-300A) / MJHL (25A-300A) Equipped
with hinges at the opposite side of clamp,
hinge clamp type joints are chiefly used for
pipework repairs.
MJH
MJHL
Double Clamp
Applications: New connections, temporary installations, repair
or partial replacement of pipework
Models & Nominal Sizes:
MJD (15A-2000A) / MJDL (25A-2000A) With a double clamp
design these couplings can easily be installed on large diameter
pipes and have good tightening characteristics.
MJD
MJDL
Elbow Repair Clamp Type
Applications: Repair of elbows and welded sections
Models & Nominal Sizes:
MJER (15A-250A) Used to repair damaged and leaking elbows and welded
sections, the lower and upper parts are separable.
