High-performance expandable joints developed by stainless steel processing experts!

The MS Joint by Meiwa Kogyo is a stretch joint that is resistant to corrosion and requires little maintenance, thanks to the use of SUS304 and SUS316. Its durability is nearly permanent compared to iron. The long stretch pipe smoothly absorbs the expansion and contraction of the main pipe, and its flexibility can withstand bends of 3 to 5 degrees, demonstrating its effectiveness in response to environmental changes after installation. Additionally, CR rubber, which is strong against chemicals, is used as a packing material. It can be widely utilized in various applications, including drinking water supply, agricultural water, industrial water piping, and sewage systems. 【Features】 ■ Completely shuts out corrosion ■ High stretch performance ■ CR rubber ring suitable for sewage systems ■ Four types available to choose from based on the diameter of the main pipe and site conditions *For more details, please refer to the catalog or feel free to contact us.
