MJG 15~400A / MJGL 20~300A / MGLP 20~200A / MJGF 65~400A / MJGFL 65~300A 

Grip type couplings are axially restrained, and good alternatives to welding, flange, grooved joint, union, etc.
MJG/MJGL have double grip rings which hold pipes tightly and make them not move or separate from each other.
MGLP with single grip ring and thinner casing and gasket is good for low pressure pipe line at lower cost.
MJGF/MJGFL with thicker casing are for higher pressure.

Application
- Industries:
water / oil & gas / shipbuilding / civil engineering & construction / general industry / machinery & equipment / maintenance of pipeline 
- Pipe Materials:
steel / stainless steel / cast iron / ductile iron / copper / concrete / Cu-Ni / aluminum / PVC / PPR / PE / GRE / GRP, etc.
* pipes of different material can be connected by coupling as long as they have same outside diameter 

Product Characteristics
* Assembly type saves work time.
* Applicable to various pipe materials. Even connects pipe of different material. (e.g. steel pipe + PVC pipe)
* Using a (torque) wrench to install eliminates worry about fire.
* No preprocessing is required at pipe ends.
* Rubber gasket accommodates vibration, impact, noise, angular deflection, and distance between pipe ends. This makes couplings seismic design.
* Installation is done at one side. It enables products to be stored or work to be done at a narrow area.
* Stainless steel design is much lighter than cast iron product and reduces load on pipes.
* Grip type couplings resist against axial movement.
* Slip (flexible) type couplings allow pipe expansion and contraction.
* Repair clamps provide semi-permanent repair with speed and no down time.
* Couplings can be assembled and disassembled several times.
