To provide an effective seal , the O – ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O – ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.
