Worcester Bosch Flexible Hose Greenstar Highflow 8716118472

The Worcester Bosch 8716118472 is a flexible hose supplied as a spare for Worcester Bosch appliances. It sits within the internal pipework of the unit, where a flexible connection is needed between fixed components, and is listed under the Pipes & Hoses spare part group. It is used across the Greenstar Highflow range.

• Weeping or dripping at either end of the hose, or damp staining around the connection points
• Cracking, swelling or hardening of the hose material with age and heat cycling
• Kinks, flattening or crushing that restricts flow through the hose
• Corrosion or pitting on the crimped ferrules and end fittings
• Falling system pressure or repeated topping up that points to a small internal leak

• Check the appliance GC number and model against the compatibility list before ordering, as several Highflow variants use different internal pipework.
• Confirm the number on the hose currently fitted matches 8716118472; earlier builds may carry 8-710-735-240-0 or 87107352400.
• Inspect the joint seals and washers at both ends and replace them if they are compressed or perished.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
