If you need this application for your spliced o-rings, we can provide this: (very tight tolerances of the cord diameter)

"Tight tolerance ground rubber cord" generally refers to
center-less ground O-ring cord stock, which is processed to achieve highly precise dimensions for demanding sealing applications. Standard extruded rubber cords typically have wider tolerances.
Key Details

Center-less Grinding: This is a secondary manufacturing process used to achieve extremely tight tolerances on the diameter of rubber cord. It removes the natural variations inherent in the initial extrusion process.
Tolerance: While typical standard tolerances for rubber cord can be as wide as +/-0.020", center-less grinding can achieve tolerances as tight as +/-0.004" or even +/-0.0002" in some precision applications.
Applications: These cords are primarily used to create custom-sized O-rings by vulcanizing the ends together, especially for metric or non-standard seal types where off-the-shelf O-rings are not suitable. They are critical for applications requiring a precise fit and reliable seal.
Material: The cords can be made from various high-performance rubber compounds designed to meet specific industry standards (e.g., ASTM, UL, CSA)

Prayers to our fellow defense contractors who suffered a horrific company explosion this morning.

Nineteen people are dead or missing after a massive blast obliterated a building at a Tennessee explosives facility on Friday, authorities said — a “mass detonation” so significant that it rattled homes miles away.
