Cap O-ring

Cap O-ring

Cap O-ring

A cap O-ring is a seal that integrates a crescent-shaped Teflon ring into the inner diameter surface of rubber, functionally utilizing the low friction properties of Teflon and the elasticity of rubber. 【Features】 1. Like rotating cap seals, it has low friction resistance and rarely experiences stick-slip. 2. It can be installed without dividing the groove, similar to rubber O-rings. 3. There is almost no increase in starting resistance even after long periods of inactivity. 4. The seal has a long lifespan. 5. It can be used at even higher speeds than cap seals. 6. It can be used in grooves for motion O-rings according to JIS B 2406. 7. When used with a retainer, it can be used up to 9.8 MPa.

Semiconductor manufacturing tools: flat rings / dicing rings

Semiconductor manufacturing tools: flat rings / dicing rings

Complex hollow shapes can also be processed in aluminum.

This is a tool used in the dicing process of silicon wafers, made from aluminum extruded pipes and stainless steel plates (SUS420J2). After plate processing and precision pressing, various surface treatments are applied according to specific requirements, including anodizing, hard anodizing, electroless nickel plating (Kanizen plating), and metal coating. There is no initial cost for basic shapes. We will provide optimal proposals based on your requests, such as "I want to change the inner cutout" or "I want to improve the surface slip properties." For more details, please contact us or refer to the catalog.

EPDM, fluorine rubber for normal temperature and high pressure as well as high temperature and high pressure! Hydrogen-resistant O-ring.

EPDM, fluorine rubber for normal temperature and high pressure as well as high temperature and high pressure! Hydrogen-resistant O-ring.

O-ring adopted for the emergency disconnect coupling used in hydrogen dispensers!

At Takashi Industrial Co., Ltd., as we advance the development of fuel cell vehicles and the construction of hydrogen stations, which are the supply side of fuel, we are conducting research and development on EPDM for low-temperature and high-pressure applications, and fluorine rubber (FKM) for both normal-temperature and high-pressure, as well as high-temperature and high-pressure applications for use in hydrogen stations. Among these, O-rings made of EPDM for low-temperature and high-pressure applications have been adopted for emergency disconnect couplings used in hydrogen dispensers at hydrogen stations operating at 70 MPa. Our company specializes not only in the manufacturing of standard circular O-rings but also in the production of deformed O-rings. If you have any rubber-related inquiries, please feel free to consult us. 【Features】 ■ Hydrogen-resistant rubber materials for use in hydrogen stations ■ Developing EPDM for low-temperature and high-pressure applications ■ Developing fluorine rubber for normal-temperature and high-pressure, as well as high-temperature and high-pressure applications *For more details, please refer to our catalog or feel free to contact us.

Vulcan Teflon capsule O-ring

Vulcan Teflon capsule O-ring

Overseas manufactured Teflon (PFA, FEP) coated O-rings

Teflon capsule O-rings combine the advantages of both Teflon and rubber, possessing the chemical resistance of Teflon while also incorporating the elasticity of rubber. This allows for performance that leverages the benefits of both materials. Additionally, they can be produced at a lower cost compared to expensive perfluoroelastomers. The sizes correspond to standard sizes such as JIS, and the coating materials are available in two types: PFA and FEP, while the core rubber is available in two types: silicone and Viton.
