Selection Guidance
The SKU ends in FKM, which is a listing code rather than independent proof of the supplied compound. Confirm the actual compound and hardness with the supplier. Before installation, verify the O-ring inside diameter, cross-section, hardness, compound, working fluid and temperature range against the equipment service specification.
Compatibility Note
The current listing does not contain a verified item-by-item size schedule or a confirmed machine-model fitment list. A brand name in the catalog title is not, by itself, proof of OEM manufacture or guaranteed fitment. Confirm the required sizes and quantities with the supplier before ordering.
