**

Figure 3-2 of the Kalsi Seals Handbook, Rev. 1 has the recommended gland details.  The gland widths in the table above are conservatively wide because Dual Durometer Kalsi Seals have not been tested with narrower glands.
   
† Actual inside diameter varies as a function of the seal material combination.
