غطاء فتحة التعبئة Baxi De Dietrich 7880089

The filling hole cap for Baxi boilers is a small but essential spare part that seals the filling loop connection point on the boiler. This cap prevents leaks and keeps the system pressurized when not in use. Over time, caps can crack or get lost during maintenance, making a replacement necessary. Designed specifically for Baxi models, it ensures a tight fit and reliable sealing. Whether you are topping up system pressure or performing a service, this cap is a simple fix to maintain your boiler's integrity.
