Sealing (Rubber Door Gasket)
Genuine Bosch part
By: Bosch
Part Number: 00612119

This sealing is a molded rubber gasket that restores a watertight, airtight seal to the appliance, helping prevent leaks and maintain proper temperature control. Replace a worn or damaged seal to stop moisture escape and reduce energy loss. What it does:

  • Forms a continuous seal around the door or access opening to prevent water or air leaks
  • Helps keep internal temperatures stable for consistent performance
  • Reduces condensation and prevents water pooling beneath the appliance
  • Can stop symptoms such as leaks, poor temperature control, or excessive frost/condensation
What's included:
  • One molded rubber sealing/gasket
Install notes:
  • Inspect the door/frame for damage and clean mating surfaces before installing the new seal
  • Gasket typically presses or snaps into a channel; no special tools usually required, but a soft tool can help seat it evenly
  • If adhesive is present on the original seal, use the appropriate adhesive rated for the appliance
  • Unplug the appliance or shut off power/water supply before starting any repair; follow all safety instructions in the owner's manual
