Bosch 1611015059 Spare Part - Sealing Frame

Genuine Bosch 1611015059 — Sealing Frame (for GSH 16‑28 / GSH 16‑30 demolition hammers)

Keep your breaker working like it should: this genuine Bosch sealing frame (Bosch part no. 1 611 015 059 / 1611015059) is the molded sealing ring/frame that sits in the housing to seal the internal strike/valve area and mating O‑rings, preventing dust and concrete slurry from entering the mechanism and accelerating wear.

Why this part matters

A worn or damaged sealing frame allows dust and debris into bearings, pistons and valve ports; replacing the sealing frame restores the intended sealing geometry and helps stop premature internal failures — an inexpensive part that protects more costly internal components.

What’s included / installation tip

Sold as the single sealing frame (Bosch 1611015059). When you replace it, inspect the adjacent O‑rings (parts called out near item 138 in the diagram) and replace any that are flattened or nicked to ensure a reliable seal.
