Energy Sector – The Silent Killer: Predictive Physics for Paraffin and Flow Assurance
https://www.ediweekly.com/energy-sector-the-silent-killer-predictive-physics-for-paraffin-and-flow-assurance/

For engineers designing and operating sucker rod pump (SRP) systems, paraffin wax deposition is the silent killer of uptime. It doesn’t announce itself with a bang or a catastrophic failure. Instead, it accumulates slowly, grain by grain, increasing mechanical loads, reducing pump efficiency, and ...

Not all tolerances are equal.
Unlike molded rubber O-rings, vulcanized O-rings use extruded cord, so different tolerances & standards apply.
COR Manufacturing cuts cord to RMA Class 1 Precision S1 for reliable consistency.
https://cormanufacturing.com/tolerances-of-vulcanized-o-rings/

The most important thing to realize about cord is that it is extruded, not molded. These 2 are very different processes which is why they have different tolerances.
