JUNT GROOVED PIPING SYSTEM DUCTILE IRON GROOVED COUPLINGS
The JUNT grooved piping system is one of the most advanced, versatile, economical and reliable systems available today. After the pipe ends are grooved a gasket is
stretched over the pipe ends. The coupling segments are then placed over the gasket and the bolts and nuts are fastened resulting In a secure and leak free joint.
A coupling can be installed 3–4 times faster than a comparable welded or brazed joint and there is no need fora flame or welding torch on the job site. A coupling can
be installed by fastening a pair of bolts and nuts while using only a wrench or spanner, whereas a comparable flanged joint requires the fastening of many bolts and
nuts with a pair of wrenches. The grooved system allows for easy material take-offs and unlike a threaded system, there is no need to allow for added pipe length for
thread engagement. With the removal of just a few bolts one can easily access the system for cleaning, maintenance, changes and or system expansion.

During assembly the gasket is first stretched over the pipe ends which forms the initial seal. As the housing segments are installed and secured the pressure responsive gasket is
slightly compressed to form a leak-tight joint. The strength of the seal is further enhanced
by internal line pressure that creates downward pressure on the lips of the gasket.

Domestic famous materials, Oval Neck bolts and heavy hoxagon nuts at ASTM A183/ISO 898,GRADE 8.8,HOT GALVANIZED.
JUNT products utilize oval neck track bolts and heavy duty hex nuts,available either in UNC
threaded or ISO metric threaded. The oval neck track bolts mate into the oval holes in the
housing segments to allow for easy tightening using only a single wrench/spanner.
