The state of deformation and stress in the sealing elements is of high importance for the projecting of the sealing rings on the electronic covers in a plane. Modeling is required in order to predict the pressurization in cabins during a flight. In this study the influence of parameters on the characteristics of materials was investigated. Because of the non-linearity caused by different geometry and high deformation, the analysis of mutual effects between a sealing ring and a gutter is a very complex three dimensional problem. Experimental testing of the sealing ring was performed as an investigation of compression, which was mostly used for the analysis of an elastomer. Numerical analysis of the behavior of a sealing element was performed using the finite element method with a variant of basic tension and states through the material. Because of the present friction between the sealing element and the gutter, a friction coefficient was involved in the numerical analysis of the present deformation. The obtained experimental and numerical values were compared. The best agreement between the experimental results and numerical analysis was reached for an application of the input set for the basic states of the elongation tension and volume compression.
