Husqvarna 541204817 Fitting Hydraulic Hex Reducer 1/2" MPT x 3/8" FPT

The Husqvarna 541204817 Fitting Hydraulic Hex Reducer 1/2" MPT x 3/8" FPT is a genuine OEM hydraulic fitting designed for the RS8500D floor saw. This component provides a secure, thread-matched transition between a 1/2" male pipe thread and a 3/8" female pipe thread in the machine's hydraulic plumbing circuit. As a factory-original part, it is manufactured to Husqvarna's exact material and dimensional tolerances, ensuring a dependable, leak-free connection within the hydraulic system. DHS Equipment supplies this part to help keep your RS8500D floor saw operating at full capacity.

Key Features

• Genuine OEM Hydraulic-Grade Construction — Manufactured to Husqvarna's pressure and thread specifications for hydraulic plumbing applications, not a generic plumbing fitting.
• Exact Thread Match — Transitions a 1/2" male pipe thread (MPT) to a 3/8" female pipe thread (FPT), matching the original hydraulic circuit routing of the RS8500D without modification.
• Verified RS8500D Fitment — Engineered specifically for the RS8500D floor saw; cross-reference part number 541204817 against your parts diagram to confirm the correct installation point.
• Leak-Free Hydraulic Integrity — A correctly seated reducer fitting maintains system pressure and prevents hydraulic fluid loss that can lead to sluggish blade drive performance or unplanned stops mid-cut.
• Hex-Body Design for Secure Installation — The hex profile allows standard wrench engagement for proper torque, reducing the risk of cross-threading or under-tightening during installation.

A hydraulic hex reducer fitting serves as a thread-size adapter within a machine's hydraulic plumbing system, allowing two hydraulic lines or components with different pipe thread diameters to connect securely. In a floor saw like the RS8500D, maintaining tight, correctly sized hydraulic connections is critical to sustaining consistent pressure across the blade drive and water delivery circuits. A failed, corroded, or improperly sized fitting can cause pressure drop, fluid leaks, or loss of hydraulic function — any of which will interrupt cutting progress and may cause broader system damage if left unaddressed.
