The GFB 25mm recirc outlet adaptor converts the recirc outlet hose connection for compatible GFB valves. Intended for use with GFB valve bodies, the adaptor provides the correct 25mm interface so hoses fit as intended. It’s a simple replacement or upgrade when matching recirculation plumbing to GFB products and helps maintain original routing without altering the valve or hose assembly.
