The Worcester Bosch 87161065300 Return Pipe is a genuine replacement pipework component designed to carry cooler water back into the boiler’s primary heat exchanger as part of the central heating circuit. As an integral part of the hydraulic loop, this return pipe ensures correct flow direction, supports efficient heat transfer and helps maintain stable system pressure and temperature balance. A damaged or corroded return pipe can lead to leaks, pressure loss and reduced heating performance, so fitting the correct replacement part is essential for dependable operation.

This return pipe is compatible with Worcester Bosch Ri and Greenstar series boilers that specify part number 87161065300 in their technical documentation. To ensure correct fitment, always verify the part number on your existing return pipe or check your boiler’s service information before installation, as pipework configurations can vary between models and system layouts.

Supplied ready for installation, the 87161065300 Return Pipe connects directly with the boiler’s existing pipework and mounting points without modification. Choosing this genuine Worcester Bosch component helps restore correct water return flow, supports efficient heating performance and maintains system integrity in compatible Ri and Greenstar boilers when fitted by a qualified engineer.
