Worcester Bosch Gas Inlet Pipe 8716117046

The Worcester Bosch gas inlet pipe, part number 8716117046, is the rigid pipe that feeds gas from the boiler's supply connection into the gas valve assembly. It is a Worcester Bosch spare component, listed under pipes and hoses, and is used across the Greenstar i ErP System range of condensing boilers. Its job is to deliver a sealed, correctly routed gas path inside the casing, so the gas valve receives an unrestricted supply at the pressure the appliance was set up for.

• A gas smell or a pressure drop on a tightness test traced to the pipe run inside the boiler
• Visible corrosion, pitting or surface rust along the pipe, particularly at the bends
• A kinked, crushed or misaligned pipe that restricts gas flow to the valve
• Weeping or staining at a compression joint or olive where the pipe meets the gas valve
• The pipe has been disturbed or damaged during another repair and no longer sits true in its clips

• Check the GC number on the appliance data badge against the compatibility list to confirm the correct pipe for your model.
• Confirm the part number 8716117046 or the alternative number 1031111 before ordering, as pipe routing differs between boiler variants.
• Have new sealing washers or olives to hand if the existing joint is being remade.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
