Preventing Failure in O-Ring Leak Paths - Official Apple Rubber Blog
An o-ring must be displaced in the gland, meaning it must be able to fully fit inside the gland while being compressed. Otherwise, the force to compress the o-ring will increase exponentially. When this occurs, the o-ring won't fully compress, leading to the creation of leak paths through which the fluid can escape. Achieving the Correct Ratio

When leakage is suspected of the O-ring ensure that the leakage is really happening rather than either outgassing (which is not uncommon in fluoroelastomers) or that in the case of helium testing the gas is not just dissolving into the polymer matrix and then passing thru the material (again not uncommon in fluorelastomers or perfluoroelastomers).

An o-ring cannot compress properly if it doesn't have enough room to expand inside a groove. A Basic Rule of Thumb for O-Ring Leak Path Ratios: The maximum o-ring volume must not exceed 90% of the minimum gland void. Essentially, you need to make sure that there's enough room in the groove to contain the entire o-ring.

Extrusion and nibbling of the O-ring is a primary cause of seal failure in dynamic applications such as Hydraulic Rod and Piston seals. This form of failure may also be found from time to time in static applications subject to high pressure pulsing which causes the clearance gap of the mating flanges to open and close, trapping the O-ring between the mating surfaces.

As stated above, spiral failure is generally caused by an O-ring both sliding and rolling at the same time. Conditions which may cause this to occur are: Eccentric components. Wide clearance combined with side loads. Uneven surface finishes. Inadequate or improper lubrication. O-ring too soft. Stroke speed (usually too slow).
