Putzmeister Spare Parts SEAL KIT FOR HYD CYL D125/180 503395

This seal kit, part number 503395, is built for Putzmeister’s hydraulic cylinder D125/180. It includes all the rings and seals you need for a full rebuild.

We use genuine polyurethane and rubber compounds, matching original Shore hardness. That means no leaks under high pressure or in tough concrete pumping conditions.

You get rod seals, wipers, O-rings, and backup rings in one bag. Everything fits the D125 piston rod and D180 bore exactly—no trimming or guesswork.

Install is straightforward for anyone who’s done cylinder work. Clean the grooves well, and these seals slide in without fighting. Lube them with clean hydraulic oil before assembly.

Keep a kit on the truck. Cylinder leaks don’t wait for a shop visit, and this set gets you back to pumping fast. No frills, just the right parts.
