WebMost o-rings are designed to operate at pressures up to 1,500 psi. At higher pressures, the material must have enough strength to resist extruding into the clearance gap. The chart shows the recommended combined limits of clearance, gap, material hardness and system pressure differential. WebAfter selecting a material that fits your sealing application, you can continue by having the Size Selector calculate the O-ring dimensions and tolerances, considering even thermal expansion and volume swelling of the sealing element. The parameter dashboard in the Results section will immediately show you if the selected O-ring size is suitable for your …
Web11 mrt. 2009 · Compress the O-ring by about 15% to 20%. The force generated by the O-ring compression can be calculated (there is some data for this in the handbook link below), but it's easier to just make up a rig and test it using the O-ring compound of your choice. Make sure the groove has more cross section area than the original O-ring, add … WebO-Ring Squeeze Compression .

WebFind your o-ring’s squeeze amount in inches by subtracting the gland depth from cross-sectional diameter with a calculator. For example, if your o-ring’s cross-sectional diameter is 1.25 inches and its gland depth is 1.20 inches, subtract 1.20 from 1.25 to determine that the o-ring is able to squeeze out a total of . Web29 jul. 2016 · When that force decays entirely, the O-ring will retain its squeezed shape even when it is no longer squeezed. A compression set is a measure of this decay, …
