Unger HiFlo nLite Pencil Brush Jets (1 Pair)
Every one of Unger's brushes come with pencil jets, but if you want to add more, here's what you need. Don't forget to add the HiFlo nLite Hose Brush Connection Kit (NLPHC). You'll want two of them for each pair of jets you add.
The pencil-style is best for standard, hydrophillic glass and fast passes.
