Puddle flange is in two halves which can be bolted around the pipe even when the pipe is in position. It can also be used as a firestop.
Available in 100mm to 300mm. Please note the 200mm diameter is a multi-clamped version.
Due to manufacturing tolerances it is also recommended that the puddle flange is bedded on Denso tape or similar.
