Verified Fit
Definition
An R+F designation confirming that a replacement element has been matched to the OEM part on dimensions, media, and end-cap/seal interface.
A verified fit means the replacement has been checked against the OEM specification — outer diameter, length, micron rating, media type and sealing interface — so it drops directly into the existing housing without adapters or modification.
Where a fit has not yet been fully confirmed, R+F flags it for engineering review rather than publishing an unverified cross-reference.
