Additional Information
The Bosch 87161068440 Return Assembly Complete is a genuine OEM hydraulic component designed specifically for Bosch Greenstar series wall-hung condensing gas boilers, integrating essential features such as the return water connection, safety valve port, pressure gauge tap, flow sensors taps, and shut-off valve taps into a single pre-assembled unit made from durable, corrosion-resistant materials. This complete drop-in replacement simplifies installation by eliminating the need to source and assemble individual parts, ensuring perfect compatibility and seamless integration with the boiler's lower hydraulic system. Key benefits include restored optimal system efficiency and heat transfer performance, enhanced safety through reliable pressure management, minimized downtime during repairs, reduced maintenance costs, and extended boiler longevity, all while preserving any remaining warranty—making it an ideal choice for professional servicing of Greenstar Combi and heat-only models to maintain quiet, energy-efficient operation year after year.
 
Why OEM Bosch Parts Matter
When it comes to maintaining and repairing existing Bosch, Buderus and Greenstar equipment, purchasing OEM (Original Equipment Manufacturer) Bosch parts is highly recommended for several important reasons: 
 
Quality and Compatibility: OEM Bosch parts are specifically designed and engineered to work seamlessly with existing Bosch equipment. They ensure optimal performance and reliability, reducing the risk of malfunctions or compatibility issues that might arise from using aftermarket parts.
 
Longevity and Durability: OEM parts are manufactured to the same high standards as the original components, ensuring that your equipment continues to function at peak performance for a longer period of time. This can help extend the lifespan of your Bosch equipment and reduce the frequency of costly repairs.
 
Warranty Protection: Using Bosch OEM parts ensures that any remaining equipment warranty is protected. Using non-OEM parts can void warranties and lead to additional costs if repairs or replacements are needed in the future. By choosing OEM Bosch parts, you ensure that your equipment continues to operate at its best, minimizes downtime, and reduces the overall cost of ownership over time.

    Fit perfectly, fixed water leak from 13 year old Greenstar. Runs like new again.
