The Husqvarna 581721504 Hose Kit is a genuine OEM replacement designed for K770 and K970 power cutters. Sourced directly from Husqvarna, this kit delivers the exact hose routing, diameter, and connection specs required by these machines — no adaptation or improvisation needed. It is the correct service solution when hoses show cracking, leaking, or wear that compromises water or fuel delivery on your cutter. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Genuine OEM Construction — Manufactured by Husqvarna to the same material and dimensional standards as the original hoses, ensuring correct internal diameter, wall thickness, and connection geometry for these power cutters.
- Kit Format for Complete Service — Provides the full hose set needed for the job, so technicians can address an entire hose circuit in one service event rather than sourcing individual lines separately.
- Confirmed Fitment for K770 and K970 — Engineered specifically for K770 and K970 power cutters; cross-reference part number 581721504 against your parts diagram to confirm the correct application before installation.
- Restores Proper Flow and Pressure — Cracked, collapsed, or leaking hoses disrupt water delivery to the blade or fuel supply to the engine, causing overheating, poor cutting performance, or stalling. This kit restores the circuit to its designed operating condition.
- Fuel and Fluid Safety Compliance — Using OEM-rated hose material ensures the lines meet Husqvarna's pressure and chemical-compatibility requirements, reducing the risk of leaks that could create fire or fluid-exposure hazards on the jobsite.
Hoses on a power cutter serve as the pathways for water and fuel throughout the machine — routing coolant to the blade guard for wet cutting and carrying fuel from the tank to the carburetor. Over time, heat cycling, vibration, and exposure to cutting slurry cause hose walls to harden, crack, or swell at connection points, leading to leaks that affect both performance and safety. Replacing worn hoses with a correctly rated kit restores proper flow, protects engine and blade components from heat damage, and keeps fluid where it belongs.
