YOUNGNAM-Couplings are the easiest way to join and repair pipes of all materials. They require no special tools or pipe-end preparation.
YN-Pipe couplings provide a fast and easy permanent connection to join two pipes together. YN-Couplings come fully assembled and ready to install. A torque wrench is the only tool required to do the job. With a minimum of two bolts, simply slip over or wrap around the ends of the two pipes and tighten the bolts to the torque mentioned on the product label.
There are different models of pipe couplings to suit different applications and pipe materials. There are restrained couplings and non restrained couplings.
Restrained couplings provide pull out resistance, axial restraint and lock the pipes together having no allowance for movement. Non restrained couplings are however designed to allow for vibration and movement but do not provide pull out resistance, axial restraint or lock the pipes together.
Flexible, lightweight, Pipe-misalignment, Vibration, Vacuum, Fire-Fighting and are used in shipbuilding, wastewater treatment, general industry, and construction.
YN-Couplings are used to join and repair any plain end pipe including steel, stainless steel, ductile iron, FRP, PVC, CPVC, C900, copper and CuNi piping.
