The Clean & Overhaul Kit RV (FKM) is intended for use during routine maintenance of Edwards RV‑series oil‑sealed rotary vane vacuum pumps. This kit contains FKM elastomer seals that restore sealing integrity within the pump and support continued reliable operation following extended use. The kit includes seals, gaskets, and an air bleed assembly needed to carry out a minor rebuild of Edwards RV3, RV5, RV8, and RV12 pumps.
