This nozzle fits 1.25 inch OD hose/pipe. The bristles are quite soft and clean. I have no problem with the bristles being sucked inwards, the suction power dropping, or the bristles falling out. The body of the nozzle is made of plastic, which is medium-soft for plastic, but doesn't have much pliability. It stays on the steel tube of my sweeping hose without any problems. I've had others that were more like rubber but they still work. Overall a smart purchase.
