The Aqua Mole Button Nose ("BN") nozzle is well suited for general drain cleaning applications. It's short body and smooth round nose make it ideal for tight turns in P traps and elbows, reducing hang ups. We've increased the functionality over typical round nose nozzles with the addition of a second grove which permits steeper thrust angles and more pulling power while maintaining a streamlined body.  This unique design permits multiple angle combinations on one nozzle. A popular and effective pattern is our "Monster Mole".
