Bosch Gasket & Seal

This O-ring is the sealing gasket between mating components, keeping fluid contained inside the system. Replacing a worn ring restores a tight, leak-free connection and helps prevent drips, moisture, and leak-related error indications.

• Creates a compressible seal between parts to prevent leaks at the joint
• Helps maintain proper system flow by stopping seepage or air ingress
• Direct replacement for rings that are flattened, cracked, brittle, swollen, or missing
• Common symptoms include dripping at the connection, moisture beneath the unit, or leak/float error alerts

• Disconnect power and shut off the water supply before servicing; wear appropriate PPE.
• Note the original ring's location; clean the groove and mating surfaces before installation.
• Apply a light coat of compatible silicone grease; avoid twisting or overstretching the ring.
• Seat evenly, reassemble, restore service, and check for leaks during a test cycle.

This O-ring seals the NTC (negative temperature coefficient) temperature sensor where it inserts into the appliance. It restores a watertight seal at the sensor port to help prevent leaks and maintain reliable temperature-sensing performance.
