Everdigm Seal Set H2080039 - 140/80 Main Drive Cylinder Piston Seal Kit

The Everdigm seal set H2080039 is the 140/80 mm main drive cylinder piston-side seal kit for Everdigm concrete pump hydraulic systems. In Everdigm drive-cylinder parts lists, H2080039 is the piston seal set and H2080040 is the rod seal set for the same 140/80 cylinder — they are not interchangeable.

Product Specifications

Application & Fitment

H2080039 fits the piston side of a 140/80 mm Everdigm main drive cylinder. If the cylinder shows internal bypass (cap-side pressure dropping, slow stroke, poor pumping pressure) the piston seal is suspect. Rod-side leakage around the chrome shaft points to H2080040 instead. Always replace piston seal, wear bands and related O-rings as a matched set — mixing old and new seals causes repeat failure.

Important Note

Do not order H2080039 for a rod leak, and do not use it on 120/80, 130/80 or 160/90 cylinders. Confirm bore 140 mm, rod 80 mm, piston groove width/depth and seal profile before dispatch. Material compound and exact machine model are not confirmed by the part description alone.
