See Figure A6-3 and Figure A6-4.
Oring squeeze formula
Did you know?
WitrynaTo create seal squeeze the gland depth must be less than the seal cross section. Calculation of Minimum O-Ring Cross Section Enter the bore diameter Add the bore tolerance to the bore diameter Enter the groove diameter Subtract the groove tolerance from the groove diameter Subtract line 4 from line 2 Divide line 5 by 2 WitrynaThe calculated value assumes the o-ring volume does not change and the cross-section remains round when stretched. When using only one back-up ring be sure to install it on the low pressure side of the o-ring. Illustration 5.3 is comprised of a great deal of information regarding o-ring compression.
WitrynaHow to Calculate O-ring Squeeze Step 1. Lay the o-ring out flat, measuring its length in inches straight from one inside tip to another while... Step 2. Hold the o-ring … WitrynaOptimum range of compression is typically 8% to 35%. For dynamic seals, the upper limit of squeeze should be reduced to 20%. For FFKM O-rings, a range of 12% to 18% is …
