Pull test results of the NK joint ring.
Report on the tensile test of the NK joint ring, which does not require a mold for the connecting O-ring.
～NK Joint Ring Test Items and Methods～ ■ NK Joint Ring Tensile Test Items Tensile Test: Conforming to JIS K 6251:2004 ■ NK Joint Ring Tensile Test Method Specimen Shape: 250mm × φ5.6mm Grip Distance: 50mm Test Speed: 100mm/min Number of Specimens: 2 Room Temperature: 23℃ ～NK Joint Ring Tensile Test Results～ 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 the two colors also demonstrated that the joining precision of the NK joint ring is high and can withstand strong tensile loads.
