Fittings for high-density polyethylene pipes (ISO outer diameter) SKX

Significant reduction in construction time is possible with mechanical construction methods! No electric fusion work required, making it easy to install joints in wet areas and tight spaces!

SKX is the industry's first joint that does not require disassembly and can be installed using a short wrench. It is ideal for connecting to existing pipes in renovation work for buildings such as apartments. Since the connection of high-density polyethylene pipes is mechanical rather than fusion, installation time has been significantly reduced. The use of fewer tools also helps to lower total costs. Water can be run immediately after connection. The low tightening torque allows for installation with short tools like a short wrench, enabling time savings and work in tight spaces. Installation is possible even in sites with water accumulation, such as from spring water, as electric fusion work is not required. There is also a rich lineup of products including reducing sockets, elbows, tees, male-threaded sockets, and female-threaded sockets.
