Companion flanges, unions, gaskets and service parts for Grundfos circulators. Flange kits connect the pump’s GF flange pattern to threaded or sweat pipe: cast iron for closed heating loops, bronze or stainless steel for domestic hot water. Pick the part by the pump’s flange pattern (for example GF 15/26 for UP/UPS 15 and 26 models and MAGNA 32) and the pipe size.
Included: the part as described; kits include gaskets and bolts where Grundfos packs them.
Ships: by parcel.
Fits: check the flange pattern or union size on your pump nameplate or in its manual.
Covered for 12 months from the date of purchase under Grundfos’s published warranty terms.
