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.

Ductile Iron: Standard coupling housings and fittings are made of ductile Iron conforming
to ASTM A536 Gr.65-45-12. The properties of Grade 65-45-12 ductile iron are as
follows;65,000 psi (448 MPa) tensile strength, 45,000 psi (310 MPa) yield strength and
12% elongation.
