Safety Leader Hose
The leader hose is a the short, high pressure, different colored hose attached to the end of the main high pressure jetting hose. They are purposely a different color from the main hose so that when the operator sees that color hose coming out of the pipe, they know the nozzle is approaching the end of the pipe, and they should shut their machine off.
Leader hoses are available in a variety of lengths, diameters, and pressures. All leader hoses come with a female end that attaches to the main high pressure hose and a male end that the nozzle attaches to. Your leader hose pressure rating must either match or be higher than your main high pressure hose. Since main high pressure water hoses can be expensive, the safety leader hose acts as the inexpensive sacrificial hose that experiences the worst wear. This keeps your main jetting hose in better condition, extending its lifespan.
