Worcester Bosch Gas Valve Gasket 87161068000

This is a Worcester Bosch gas valve gasket, supplied under part number 87161068000. It sits at the gas valve on Worcester Bosch Greenstar appliances, where it forms the seal between the valve body and the mating surface so gas is delivered to the burner assembly without leaking past the joint.

The gasket is a service item within the Gaskets, Seals & Washers group. Once the gas valve is disturbed for repair or replacement, the seal at that joint should be renewed as a matter of course.

• A detectable gas smell around the gas valve area, confirmed with leak detection fluid at the joint.
• Visible flattening, cracking, hardening or deformation of the existing gasket once the valve is removed.
• Soot staining or discolouration at the valve-to-manifold joint, suggesting gas has been escaping past the seal.
• Combustion readings that drift or fail to settle after the gas valve has been serviced or replaced.
• Intermittent ignition or flame instability traced back to the gas valve assembly.

• Check the GC number on the appliance data badge against the compatibility list, as several Greenstar RI and ErP variants use this gasket.
• Confirm the part number 87161068000 or the alternative number 1015079 before ordering, particularly if the appliance has been worked on previously.
• If the gas valve is being replaced rather than resealed, check whether any other seals at the same joint are also due for renewal.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
