Bosch 1609203B13 Spare Part - Seal Ring

Bosch 1609203B13 — Genuine Bosch seal ring designed to restore an airtight seal in Bosch professional wet/dry vacuum extractors. The part is listed in Bosch spare‑parts diagrams as “Seal Ring” (part no. 1609203B13 / 1 609 203 B13) and is the small flexible sealing ring that sits around the suction/blower housing to prevent air leaks and maintain pump/suction performance.


Why this part matters: a worn or torn seal ring lets air bypass the motor/blower, cutting suction and letting dust escape; replacing 1609203B13 typically restores full vacuum performance without replacing larger assemblies. Sellers and parts diagrams list it as an inexpensive, straightforward replacement that installs without specialist tools.


Example models this part is listed for (examples from Bosch power tool parts diagrams and parts retailers):

- Bosch GAS 12‑50 RF (type 06019758xx / 06019759xx).

- Bosch GAS 14‑20 RFB (type 06019767xx).

- Bosch GAS 25 L SFC (type 0601979103 / GAS 25).

- Bosch GAS 50 / GAS 50 M (listed as compatible in parts lists).


Part identifiers and notes: commonly referenced as 1609203B13 or 1 609 203 B13 (some listings also show related variants such as 1609203C66 for similar seal positions in other sub‑models), and the UPC/stocking references appear on parts listings for ordering. Check the parts diagram position (often shown as pos. 220 in diagrams) for your exact model to confirm fit.


Short summary for repair: this genuine Bosch seal ring is a low‑cost, direct replacement to stop leaks and recover suction on compatible GAS‑series vacuums — a quick part to have on hand when servicing your unit. It’s one of the common power tool parts that fixes poor suction without replacing major assemblies.
