Conductive and heat-resistant gasket "Arrowhead type (tube)"

Conductive and heat-resistant gasket "Arrowhead type (tube)"

Strongly compressing a D-shaped gasket from the side! Introducing a spearhead-shaped tube.

The "Arrowhead Type (Tube)" is a conductive and heat-resistant gasket that is installed by pushing the arrowhead part into a slit. When taking shear direction contact with the housing lid or door, the "D-type" gasket is strongly compressed from the side to increase the contact area. Please design the width of the slit for installation to be 0.15mm to 0.30mm wider than the dimension W1. 【Features】 ■ Installed by pushing the arrowhead part into a slit ■ When taking shear direction contact with the housing lid or door, the D-type gasket is strongly compressed from the side ■ Increases the contact area *For more details, please refer to the PDF document or feel free to contact us. *Product sample sets are currently available! Please apply through the inquiry.

EPDM molded gasket 'S-2950' <PTFE coated product>

EPDM molded gasket 'S-2950' <PTFE coated product>

Introducing Sowa's gaskets, suitable for use with resin-made and resin-lined flanges!

The S-2950 is a gasket formed by pressurized heating of PTFE film onto EPDM rubber molded products, creating a unified bond. It is suitable for piping lines that require chemical resistance and corrosion resistance, where surface pressure cannot be obtained, such as PVC and GL piping, and can also be used with resin and resin-lined flanges. The size is 3.0mm thick, with specifications ranging from 10K-15A to 300A; other sizes are available as PTFE-wrapped gaskets. 【Features】 ■ PTFE film is pressurized and heat-formed onto EPDM rubber molded products, creating a unified bond. ■ Suitable for piping lines that require chemical resistance and corrosion resistance, where surface pressure cannot be obtained, such as PVC and GL piping. ■ Size: Thickness 3.0mm / Specifications 10K-15A to 300A (Other sizes are available as PTFE-wrapped gaskets, only for full face). ■ Operating conditions: Temperature -40℃ to 120℃ / Pressure up to 0.98MPa. *For more details, please refer to the PDF document or feel free to contact us.

Gasket Packing Q&A No. 8 Measures Against Gasket Penetration Leakage

Gasket Packing Q&A No. 8 Measures Against Gasket Penetration Leakage

I want to prevent gas leaks from the joint sheet! I will propose measures against gasket permeation leaks!

◆Issue Details 　　〇When using the joint sheet as a gasket and conducting a leak test, the leakage does not stop. ◆Possible Factors 　　〇The gasket shape is FF type → Insufficient surface pressure 　　〇No paste applied → Gas permeates 　　〇Thickness is 3.0 mm → Gas is prone to permeation, significant stress relaxation ◆Countermeasures 　　〇Change the gasket shape to ring type (inner packing) 　　〇Apply gasket paste to the flange contact surface and inner diameter end face 　　〇Reduce gasket thickness to 1.5 mm (especially for smaller sizes, below 200A)

Daiko Tokyo Branch Processing Example No. 17 Gaskets and Industrial Products!

Daiko Tokyo Branch Processing Example No. 17 Gaskets and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We utilize various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. 【Processing Example】 We processed Viton rubber with a thickness of t5. Since the hardness of the rubber is 80°, which is somewhat hard, we reduced the processing speed when using the water jet compared to regular rubber. This time, we set the speed to approximately 1000mm per minute. We also have other thicknesses of Viton rubber in stock, so please feel free to inquire.

Daiko Tokyo Branch Processing Example No. 9 Gaskets and Industrial Products!

Introducing examples of processing gaskets, packing, and industrial products! We process them using various machines, including water jets (high-pressure processing machines)!

Our company has been processing and selling gaskets, packing, and industrial products for over 45 years. We use various processing machines, including one of Japan's largest water jets (high-pressure cutting machines), plotters, and press processing, to propose products to our customers. Please feel free to contact us for any inquiries regarding processing. 【Processing Examples】 We cut a neoprene rubber sheet to the required length using a water jet and processed it into a cylindrical shape with adhesive. The smaller the diameter, the more material rebound occurs, increasing the difficulty of production. When processing as a single piece, it requires processing from a rubber sheet with a thickness of 60mm, and the machines that can handle this are limited. If adhesive processing is possible, we can offer it at a low cost.
