Seals and gaskets that prevent leaks of various fluids such as oil, water, air, and gas. Are you having trouble selecting them? When choosing seals and gaskets, it is very important to consider the method, shape, and material that match the usage environment, such as temperature, fluid, and pressure. Therefore, we have prepared the "Introduction to Seal and Gasket Technology" to help with the selection of seals and gaskets and to understand the basic technology. Please take this opportunity to take a look. We are currently offering a free CD-ROM containing the "Introduction to Seal and Gasket Technology" to the first 30 people who respond to the survey from the "Contact Us" section below! *You can view a digest version from "Download."

～Test Items and Methods for NK Joint Ring～ ■Tensile Test Items for NK Joint Ring Tensile Test: Conforming to JIS K 6251:2004 ■Tensile Test Method for NK Joint Ring Specimen Shape: 250mm × φ5.6mm Gripping Distance: 50mm Test Speed: 100mm/min Number of Specimens: 2 Room Temperature: 23℃ ～Tensile Test Results for NK Joint Ring～ To clarify the results, the test was conducted using an NK joint ring made of two different colored rubbers. ■Results■ The rupture occurred not at the boundary between the two colors (the adhesive surface of the two types of rubber), but in the central part where the force was applied. The cross-section spanning both colors also demonstrated that the joining precision of the NK joint ring is high and can withstand strong tensile loads. Test Sample: NK Joint Ring (different colors) Test Item: Tensile Test (Joint Section) Maximum Tensile Load (Unit: N): 156
