Make sure the groove has more cross section area than the original o ring add a bit extra to allow for thermal expansion.
O ring clamping force calculation.
The o ring calculator tool is intended to form the basis of an o ring installation and assist with selection of o ring and hardware dimensions.
Figure 5 primary wall contact stress profile for unrestrained unlubricated axially loaded o ring the only fixed case stress parameters results vernacular for this discussion includes primary wall and lateral wall the primary wall or walls are the surfaces which move together to force the compression of the o ring.

Both are interlinked thus ensuring the best possible combination of the calculated o ring size and material choice.
See table below for how much clamping force is available from manual clamp straps of various sizes with a 2 to 1 clamping force ratio to compare with power clamp forces.
O ring compression force is the force required to compress an o ring the amount necessary to maintain an adequate sealing line of contact.
Sometimes an approximate method is good enough.

Info o ring compression.
Clamping force calculations can be quite complicated.
The force generated by the o ring compression can be calculated there is some data for this in the handbook link below but it s easier to just make up a rig and test it using the o ring compound of your choice.
You need to be registered and logged in to see the o ring calculation software.

See the below compression force table along with the compression load tables in the links below.
Parker s o ring selector is an engineering tool which offers o ring material and size selection combined in one tool.
This tool is optimized for desktop devices.
