Husqvarna 541204588 Fitting Pipe Coupling 3/8 Inch Galvanized

The Husqvarna 541204588 Fitting Pipe Coupling 3/8 Inch Galvanized is a genuine OEM component designed for the FS4800D and RS8500D floor saws. This coupling delivers the exact thread engagement and dimensional match required for a secure, leak-free plumbing connection on these machines. As a genuine Husqvarna part, it is manufactured to the same specifications as the original, ensuring the connection point functions exactly as intended. DHS Equipment supplies this part to help keep your equipment running at full capability.

Key Features

• Galvanized Steel Construction — the zinc galvanized finish resists corrosion in wet-cutting environments where water and slurry are constantly present, extending the service life of this connection point.
• Correct 3/8 Inch Thread Specification — matched to the exact thread size and pitch used in the original plumbing assembly, allowing this fitting to seat and seal properly without modification.
• Genuine OEM Part — manufactured to Husqvarna's specifications, this coupling meets the same dimensional and material standards as the part it replaces, maintaining the integrity of the water supply circuit.
• Confirmed Fitment for FS4800D and RS8500D Floor Saws — cross-reference part number 541204588 against your parts diagram to confirm correct placement before installation.
• Restored Water Flow Integrity — a failed or leaking coupling can disrupt blade cooling and dust suppression; replacing it with this fitting restores consistent water delivery to the cutting system.

A pipe coupling fitting connects two sections of the water supply line that runs through a floor saw's blade cooling and dust suppression system. On machines like the FS4800D and RS8500D floor saws, maintaining a sealed, uninterrupted water circuit is critical — water keeps the diamond blade cool during cutting and prevents harmful silica dust from becoming airborne. When a coupling cracks, corrodes, or loses its seal, water pressure drops and flow becomes inconsistent, compromising both blade life and operator safety. Replacing a worn or damaged coupling with the correct OEM fitting restores the system to its intended operating condition.
