The GFB 33mm recirc adaptor provides a 33mm interface for recirculation outlet hoses on compatible GFB valves. As a recirc outlet hose adaptor, it enables proper hose connection to GFB valve outlets and is used to match or repair the recirc plumbing without altering the valve. It’s intended for applications where the larger 33mm outlet is required to maintain the original recirculation routing.
