20230508 Tuning In the O-Ring Size

 


Parker handbook 


4.3 Face Type Seals

“Face type seals are sometimes rectangular. In designing such

a seal to receive a standard O-ring, the inside corner radii of

the groove should be at least three times (ideally six times) the

cross-section diameter of the O-ring to avoid over-stressing

the ring or causing corner creases that would potentially leak.

The cross section of the o ring is 0.139 inches

The minimum internal bend radius is 3*0.139 = 0.417 


This had to be adjusted within the design

Diametral clearance. 


The O-ring we are looking for has a dash number of 255 


5.609 + 0.005 = 5.614
