[Free Sample Offered] Improved sealability and handling! Achieved a locking sensation with increased density.

The "8851ND CleaLock" is a high-performance universal gasket that overcomes the issues encountered during installation, such as the inability to achieve a soft tightening feel with expanded graphite gaskets. It enables the attainment of a typical gasket tightening feel, effectively resolving concerns related to one-sided tightening. Additionally, its heat resistance and chemical resistance remain astonishingly high due to its remarkable recovery rate, allowing for excellent sealing performance even under thermal cycling conditions. Furthermore, it significantly improves the issue of flange adhesion that has been a challenge with conventional expanded graphite gaskets. 【Features】 ■ High sealing capability ■ Minimal reduction in surface pressure ■ Excellent heat and chemical resistance ■ No paste required ■ Resistant to degradation even during long-term storage *If you would like a free sample, please contact us. If you provide specific testing conditions, we will consider samples tailored to those dimensions. (Examples of testing conditions: temperature, pressure, fluid, equipment used, dimensions (thickness, outer diameter, inner diameter, etc.), estimated annual demand, and others)

A surface adhesion suppression treatment is applied, contributing to a reduction in maintenance labor! For steam lines and other industrial gaskets.

"MacFoil (expanded black lead)" has excellent heat resistance, very low stress relaxation, and can maintain sealing performance over a long period. By combining with metals, its handling properties are improved, and it is widely used as gaskets for steam lines and other industrial applications. However, while its sealing performance is very good, it adheres too well to flanges, causing maintenance to become a concern. The 'Cleamatex' series has a surface treatment to suppress adhesion, making it possible to reduce maintenance effort. 【Features】 ■ Excellent heat resistance, thermal conductivity, and chemical resistance ■ High compressibility and easy to conform ■ Minimal sticking at high temperatures ■ Can be punched in Thomson type *For more details, please refer to the PDF document or feel free to contact us.

Are you having trouble with leaks from your heat exchanger recently? We are committed to addressing leaks with our extensive experience!

The "HEAT EXCHANGER・VESSEL SEALS" is a comprehensive catalog for heat exchangers. Are you experiencing leaks from gaskets in old heat exchangers that are 10, 20, or even more years old? Many existing designs use spiral gaskets or metal jacket gaskets, but leaks from the gasket area have been increasing in recent years. Based on our extensive track record, we propose gaskets tailored to your equipment! We introduce products such as "2711・2715 DryFlex・2717," which excel in gas sealing, as well as "8851ND CleaLock" and "1500 HOCHDRUCK-Pro." [Contents] ■ Proposals for sealing solutions in heat exchangers ■ 2711・2715・2717 ■ Part numbers, materials, and shape symbols ■ CleaLock 8851ND・1500・MacGuard (grommet options) ■ MetaLock 2660・2670・2730 Kamflex, etc. *For more details, please refer to the PDF document or feel free to contact us.

"Free sample available" Gaskets that meet the standards of excellent heat resistance, chemical resistance, and pressure resistance in accordance with air pollution prevention guidelines.

The "1500 HOCHDRUCK-Pro" is a high-performance gasket that meets the air pollution prevention guidelines "TA-LUFT" in Germany, a leading country in environmental protection. Thanks to its multilayer reinforced structure, it can be used in areas where semi-metallic or metallic gaskets are typically employed. Additionally, it can serve as an alternative to spiral gaskets in urgent situations and is suitable for a wide range of applications, including steam union gaskets. 【Features】 ■ Excellent heat resistance, chemical resistance, and pressure resistance ■ Minimal stress relaxation (reduction in surface pressure) ■ Superior sealing performance ■ Excellent handling properties ■ Outstanding emergency response capability "Free Sample Offer" Please feel free to contact us for your request. If you provide specific testing conditions, we will consider samples tailored to those dimensions, so please get in touch. 【Testing Conditions Examples】 ■ Temperature ■ Pressure ■ Fluid ■ Equipment used ■ Dimensions (thickness, outer diameter, inner diameter, etc.) ■ Estimated annual demand ■ Others *For more details, please refer to the PDF document or feel free to contact us.

It can demonstrate excellent sealing performance even under low tightening surface pressure.

The cam profile gasket is a gasket that uses a sealing layer on the surface of a gasket core processed into a special tooth shape. It has excellent pressure resistance (43.1 MPa) and heat resistance. 【Features】 ■ Can solve insulation issues at high temperatures ■ Usable with fluids that are prone to polymerization reactions ■ Usable in locations where issues due to vibration occur *For more details, please download the PDF or feel free to contact us.

Shut out infiltration and leakage! Improved heat resistance with grommet processing.

"MacGuard" is the name of an option that applies crimping processing of SUS316L or Hastelloy to the inner and outer diameters of gaskets. By adding MacGuard as an option for gaskets, it is possible to significantly improve sealing performance, contamination prevention, pressure resistance, heat resistance, and more. 【Features】 ■ Shuts out permeation leakage ■ Improved heat resistance ■ Blocks the occurrence of contamination ■ Protects the gasket from fluids ■ Significantly suppresses cold flow of fluorine-based gaskets ■ Prevents gasket adhesion ■ Greatly improves the handling of gaskets *For more details, please refer to the PDF document or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.

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.
