This is a genuine OEM part. The Husqvarna square nut is compatible with many brushcutter devices. The metal nut helps to secure the suspension guide rail, and is sold individually. A wrench is required for the proper repair.
This is an authentic Husqvarna replacement part. The nipple is commonly found in Husqvarna chainsaws and power cutters. This part is made of high-quality plastic, and comes with an O-ring pre-installed at one end. It allows water to flow through the wet cutting system to prevent excessive dust and flying debris while cutting.
