Bunn 20526.15 SIL011 .450 Aftermarket Black Flow Washer Only

The Bunn 20526.15 aftermarket flow washer is a precision-engineered .450 flow control gasket designed for commercial coffee brewing systems. This black flow washer serves as a critical component in maintaining consistent water delivery and pressure regulation within the sprayhead assembly. Manufactured to meet or exceed OEM tolerances, this EPDM rubber washer provides a reliable seal to prevent bypass leaks and ensure accurate extraction cycles. When diagnosing erratic volume outputs or inconsistent brew strengths, technicians often find that these flow control washers have calcified or deformed over time. Replacing the worn commercial brewer seal with this high-performance aftermarket equivalent restores the necessary flow restriction for optimal saturation. It is cross-compatible with several high-volume Bunn beverage equipment models, specifically replacing the Bunn 20526.15 part number. This component is essential for preventative maintenance schedules aimed at reducing downtime in high-traffic foodservice environments.
