It helps improve sealing, protect against heat, and reduce the cost of sealing fixtures.
EO Ring Cord was developed as the optimum sealing material through research on leak-test seals. It comes in a 3-meter cord form and can be cut to any desired length for use. The “EO Ring Kit” containing all necessary items for adhesion is also available.

basic information
EO Ring Cord with elliptical cross section can be cut to any length and used by gluing the ends together to form a ring. The ellipse shape has a large crushing allowance, and spacers (stoppers) can be placed between the work and the fixture. So, the work and fixture can be thermally insulated, minimizing the effect of fixture temperature and ensuring stable measurement. Also, it significantly enhances sealing.

Applications/Examples of results
◆Improvement of sealing Elliptical shape allows more margins to squeeze, enhancing sealing performance. Rings with elliptical shape hardly come off from the grooves and can be used in relatively small sealing area. ◆Protection against heat Spacers (stoppers) can be placed between the work and the fixture. The work and the fixture can be thermally insulated, allowing for stable measurements with minimal effect from fixture temperature. ◆Reduction of sealing costs It can be used for complex sealing shapes. No need for special gaskets or gasket molds. It also can be used for prototyping when making o-rings with molds. With the EO Ring Kit, make o-rings of any size at low cost.

Company information
Cosmo’s Air Leak Testers began with the automation of cylinder block airtightness tests for engines in 1970. Our products are utilized in various fields including automotive parts, gas, water supply, medical, electrical, electronics, and food. In line with the overseas expansion of Japanese automakers, we began our own overseas expansion in 1983. We now have 24 sales and service offices in 13 countries. We are offering proposals and providing after-sales services overseas as in Japan. Currently, in order to support the electrification of automobiles, our products are being used for leak testing of parts for electrification such as battery cases and inverters as well as for fitting testing of electric power connectors. We are contributing to the efforts by our customers to prevent emissions of CO2. In various regions of South and Southeast Asia, we are donating pressure measuring equipment to technical schools to improve the quality of education and exchange technologies with local machinery manufacturers. We have been making every effort to help improve the industrial base through local manufacturing of high-quality leak testing equipment.
