The "Soft Seal Partition Valve with Base for High-Density PE Pipe (JIS Diameter)" is a soft seal partition valve equipped with a mechanical connection for high-density PE pipes (JIS diameter). It is a convenient product for installing partition valves in plumbing work using high-density PE pipes (JIS diameter). The connection part with the pipe features a flange-less mechanical connection structure, allowing it to be connected to the pipe by tightening bolts and nuts with a wrench. By omitting the flange connection work, the risk of water leakage from the flange area is reduced, enhancing safety. Additionally, since joining materials (gaskets, bolts, and nuts) are not required, it also leads to cost savings. Moreover, fusion work is unnecessary, and installation can be carried out without the need for specialized fusion machines, clamps, generators, or other equipment. Even in exterior construction projects with limited construction days or times, it can be installed without being affected by site conditions such as water presence or weather, allowing for immediate water flow after installation, thus enabling time and schedule reductions. This product comes with a dedicated base attached to the lower part of the valve body. In areas with poor soil conditions, a bottom plate is necessary to stabilize the partition valve, but this dedicated base allows for stable installation. Furthermore, it prevents tilting of the partition valve due to ground changes or aging of the pipeline after installation, resulting in improved stability compared to conventional products.

SKX is the industry's first hybrid pipe fitting that does not require disassembly and can be installed using a short wrench, making it ideal for switching between existing and new pipes during renovations in apartments and similar settings. The product we are introducing this time is the "SKX Socket for PVC Pipes for Water Supply." It is a fitting that allows for the mechanical connection of PVC pipes. Since no solvents are used during the connection of PVC pipes, there is no need for drying or curing, and water can be passed through immediately after connection. SKX is a through-type fitting, allowing for easy installation and connection from existing pipes. Additionally, it requires low tightening torque, enabling installation with short tools like a short wrench, which reduces construction time and allows for work in tight spaces. Disassembly is possible simply by loosening with a tool. With a wide range of options including diameter-reducing sockets, elbows, tees, male-threaded sockets, and female-threaded sockets, as well as a rich lineup for hybrid pipe connections, it accommodates various connection needs.

SKX is the industry's first hybrid pipe fitting that does not require disassembly and can be installed using a short wrench, making it ideal for switching between existing and new pipes during renovations in apartments and similar settings. The product we are introducing this time is the "SKX Socket for High-Density Polyethylene Pipe (ISO) × Poly Pipe." It is a fitting that allows for easy mechanical connection between high-density polyethylene pipes (ISO) and water supply polyethylene pipes. Since the connection of high-density polyethylene pipes (ISO) is a mechanical connection rather than a fusion connection, it can be installed in wet areas and connected to existing pipes. Additionally, it significantly reduces installation time, and water can flow immediately after connection. For connecting water supply polyethylene pipes, there is no need for core drilling, allowing for immediate installation after cutting the pipe. The SKX is a through-type fitting, enabling easy installation and connection from existing pipes. Furthermore, it requires low tightening torque, allowing for installation with short tools like a short wrench, which facilitates time-saving and installation in narrow spaces. Disassembly is possible simply by loosening it with a tool. With a rich lineup including diameter-different sockets, elbows, male-threaded sockets, and female-threaded sockets, it accommodates a variety of connections for hybrid pipe connections.

The product we are introducing this time is the "SKX Socket for High-Density Polyethylene Pipe (ISO) × Steel Pipe." It is a fitting that allows for easy mechanical connection between high-density polyethylene pipes (ISO) and steel pipes. Since the connection of high-density polyethylene pipes (ISO) is a mechanical connection rather than a fusion connection, it can be installed in wet areas and connected to existing pipes. Additionally, it significantly reduces installation time, and water can flow immediately after connection. When connecting steel pipes, there is no need for threading the pipes, allowing for immediate installation after cutting the pipe. Furthermore, since flange processing is unnecessary, it can be connected without flanges. SKX features a through-type design, enabling easy installation and connection from existing pipes. It also has a low tightening torque, allowing for installation in tight spaces using short tools like a short wrench. Disassembly is possible simply by loosening with a tool, allowing for separation from the pipe. With a rich lineup that includes diameter-reducing sockets, elbows, and male-threaded sockets, as well as various hybrid pipe connections, it accommodates a wide range of connections.
