Customers struggling with steam! Here is the solution!

Are you using PTFE or joint sheets and experiencing significant leakage with steam? Our expanded graphite gaskets improve the handling issues and are widely used in the market. Here are two of our gaskets: - 8851ND CleaLock The 8851ND CleaLock is our original gasket made from high-density expanded graphite combined with stainless steel. This improves handling and provides a good tightening feel, which has received great acclaim from operators. Additionally, we have a quick turnaround time, typically responding within 3-4 days, and we will do our best to accommodate urgent requests, so please feel free to contact us. - 1500 HOCHDRUCK-Pro The 1500 HOCHDRUCK-Pro retains the soft expanded graphite while featuring multiple layers of stainless steel. It has 5 layers of stainless steel at a thickness of 3mm and 7 layers at a thickness of 4mm. It can be used under high pressure, making it a popular choice as an emergency substitute for metal gaskets, and of course, we can also provide quick delivery.

The gasket during flange release suppresses the sticking of the packing, significantly reducing flange cleaning time!

The anti-seizing spray eCLEAR is a gasket anti-seizing spray based on inorganic minerals. Please apply it to the gasket before tightening. This will help suppress seizing during opening. <Features> - Prevents gasket burning (seizing) to flanges! - Compatible with most gasket materials! - Significantly reduces flange cleaning time! - Excellent heat resistance up to 800℃ - Can be used in conjunction with gasket seal paste (seal auxiliary agent)! *It cannot remove gaskets that have already seized. Please apply it beforehand. *The heat resistance temperature depends on the performance of the base material gasket.

[Free Sample Offered] Easy, convenient, and with excellent permeability, making the difficult task of removing bolts easy!

If you apply an appropriate amount to the bolt you want to loosen, it will penetrate in about 30 minutes. Applying it the day before will make it more effective in loosening. This is expected to shorten the time required for disassembly and inspection. 【Features】 ■ Improved equipment operating rate ■ Cost benefits from reusing bolts ■ Reduction in the number of bolts to be removed and associated costs *For more details, please download the PDF or feel free to contact us. *If you would like a free sample, please reach out to us through the contact form.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.
