Key Features

• OEM Thread Specification — Manufactured to Husqvarna's exact 1/2 MPT x 1/8 FPT thread dimensions, ensuring a secure, pressure-rated seal in the hydraulic circuit.
• Drop-In Hydraulic Connection — Threads directly into the existing hydraulic ports on compatible floor saws with no reworking of lines or fittings required.
• Floor Saw Compatibility — Confirmed fitment for the RS8500D and Pro65G floor saws — Husqvarna's heavy-duty walk-behind slab cutting platforms.
• Leak-Free Hydraulic Integrity — A correctly installed reducer fitting prevents pressure loss and fluid leakage that can starve hydraulic components and cause erratic blade or drive performance.
• Genuine Husqvarna OEM Part — Sourced directly through the Husqvarna OEM supply chain, ensuring the fitting material and thread form meet the tolerances specified for high-pressure hydraulic applications.

A hydraulic hex reducer fitting serves as a threaded adapter that connects two hydraulic lines or ports with different thread sizes — in this case, a 1/2-inch male pipe thread to a 1/8-inch female pipe thread. On floor saws like the RS8500D and Pro65G, the hydraulic system powers critical functions including blade drive and water delivery, so every fitting in the circuit must hold pressure reliably. A failed or mismatched fitting can cause hydraulic fluid loss, pressure drop, and ultimately machine shutdown mid-cut — making the correct OEM replacement the only practical choice for a working crew.
