Bosch O-ring - 1610210094

20,0x3,0 MM

Original Bosch sealing O‑ring, part number 1610210094 — a precision-molded rubber O‑ring sized 20.0 x 3.0 mm, made to restore the hammering seal in Bosch rotary and demolition hammers.

Fits a number of Bosch models including GBH 5‑40 DCE, GBH 5 DCE, GBH 38 and GSH 5 E (also used on tools referenced as 11244 E / Type 0611244139), so you can drop this into the seal groove and stop air or grease leaks that reduce impact performance.

Made as an original Bosch replacement, the elastomer construction resists tool grease and repeated impact cycles — a small, inexpensive part that keeps the hammer mechanism operating correctly.

If you need a single, direct replacement to fix sealing issues in your hammer, this genuine Bosch O‑ring is the exact-spec power tool parts item to use.
