This small replacement sealing ring restores a watertight connection in the appliance's fluid or valve fittings, helping prevent leaks and maintain proper operation. Replace worn or damaged rings to stop drips and avoid water-related damage. What it does:

• Forms a seal at pump, valve or hose connections to prevent water leakage.
• Commonly replaced when the ring becomes cracked, brittle, flattened or deformed.
• Symptoms that indicate replacement: visible leaks, pooling under the appliance, or intermittent water flow issues.
• Protects internal components by maintaining a reliable seal and preventing water intrusion.

• Disconnect power and shut off the water supply before starting any repair.
• Inspect mating surfaces and clean away debris or old sealant before installing the new ring.
• Fit the ring evenly without twisting; avoid overstretching or using metal tools that can nick the ring.
• If the original used lubricant, use only manufacturer-recommended lubricants; otherwise install dry.

Foam seal tape creates a tight seal between your cooktop and countertop to contain spills and provide heat isolation. Replace when adhesive weakens.

This valve is a water-flow control assembly that opens and closes to direct water where the appliance needs it. Replacing a worn valve restores proper water delivery and helps stop intermittent filling or leaks. What it does:

• Opens and closes to control water flow into the appliance
• Enables timed or sequence-based filling during cycles
• A faulty valve can cause no-fill, overfill, or continuous filling symptoms
• Prevents unintended water flow when functioning correctly

• Test for leaks and correct operation before returning the appliance to service

The Repair-Set is an OEM part for Bosch cooktops. This set includes precision-engineered nozzles that are crucial for the correct mixing of air and gas before combustion, which ensures efficient and even heating. The Venturi nozzles are key components in maintaining the performance and safety of gas cooktops, facilitating the proper flame size and consistency necessary for various cooking needs.

Causes of a bad burner Venturi nozzle can include clogging due to food spills or cleaning products, natural wear and tear, or improper initial installation.  

Symptoms of a malfunctioning Venturi nozzle include:

• Irregular flame size or color
• Weak or uneven heating
• Excessive soot or yellow flames indicating incomplete combustion

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.

The Nut is an OEM component specifically designed for select Bosch gas cooktops. As a fastening mechanism, it firmly holds valves and brackets without loosening.  

Zinc plating resists corrosion ensuring dependable seating even under pot handles and continuous thermal expansion/contraction. Precision threading aligns without galling or binding that could jeopardize safe regulator positioning.

Causes requiring nut replacement commonly relate to wear through threads no longer maintaining clamping pressure on brass regulators over decades of use. Physical damage or over-tightening during assembly/service could also crack or distort housings.

Symptoms signaling the need for new nuts include:

• Gas leaks detected around valve connections or mounting points
• Loosened assemblies enabling unwanted vibrations from frequent cooking  
• Difficulty reaching proper tightening torques without hardware damage

This OEM Bosch replacement nut is also compatible with Thermador, Gaggenau, and some Kenmore ranges.
 

Pressure regulator for gas cooktops maintains consistent gas flow to burners. Replace if leaking gas odor, damaged vent, or worn seals detected.
