Bosch 1609203V36 Spare Part - Fitting

1609203V36 supersedes older part numbers: 1609390578.

Genuine Bosch 1609203V36 — replacement connection fitting for dust extraction and vacuum interfaces. This original Bosch outlet/adapter is the molded plastic connection piece used to join the tool or vacuum inlet to the flexible suction hose; the outlet diameter measures about 35 mm so it mates with standard Bosch extraction hoses.

Fits many Bosch workshop vacuums and extraction-equipped tools — for example GAS 10-50 RFH, GAS 12-50 RF / RFH, GAS 14-20 RFB, GAS 25 / GAS 25 L SFC and GAS 50 / GAS 50 M models, and also matches the connection used on several PAS-series vacuums and some older Bosch rotary hammer/drill models. Use this part where the hose-to-tool connection is worn, cracked or no longer seals.

Marked and sold as Bosch part 1609203V36 (also shown in listings as 1 609 203 V36), this is the direct replacement fitting produced to Bosch’s original specifications — a simple swap that restores a snug, wobble-free hose connection so your extraction performs as intended.

If you need a single, reliable connection piece to restore dust extraction on a compatible Bosch vacuum or tool, this genuine Bosch 1609203V36 fitting is the exact replacement to get the hose sealed and the system working again.
