Wacker Neuson 5000163777 Fitting 1/2 Mnpt X 3/8 Barb

The Wacker Neuson is a genuine OEM Fitting 1/2 Mnpt X 3/8 Barb designed for the BFS 2020AS and BFS 1318AS series floor saws. Sourced directly from Wacker Neuson, this fitting carries the same part number and specification as the component installed at the factory, so you can be confident it threads and seals exactly as intended. It is a direct-fit replacement for both the BFS 2020AS Saw and the BFS 1318AS Self-propelled Walk-behind Saw, covering the two primary models in the BFS floor saw lineup.

Key Features

• Genuine OEM Sealing Integrity — Machined to the same thread form and barb geometry as the original, ensuring a leak-free connection at the 1/2 MNPT male thread and a secure 3/8 barb hose grip.
• Drop-in Installation — The 1/2 MNPT thread engages the existing port with no re-tapping or adapter required; the 3/8 barb accepts the original hose line without modification.
• Confirmed Fitment for BFS Floor Saws — Verified for the BFS 2020AS and BFS 1318AS Self-propelled Walk-behind Saw, covering both current models in the Wacker Neuson BFS concrete saw family.
• Sustained Fluid Flow — A properly seated fitting keeps coolant or water flowing to the blade, protecting both the cutting blade and the slab surface from heat damage during extended cuts.
• Verified Part Number — Ordering by Wacker Neuson part number 5000163777 eliminates guesswork and ensures you receive the correct fitting geometry for your machine.

A floor saw fitting of this type connects a threaded port on the machine's water or coolant circuit to a flexible hose line, controlling the flow of blade-cooling water during cutting operations. The 1/2 MNPT male end threads into the machine body or valve assembly, while the 3/8 barb retains the supply hose under pressure. When this fitting cracks, corrodes, or develops a weeping thread seal, cooling flow to the blade is interrupted, leading to premature blade wear, scoring of the concrete surface, and potential overheating of the saw's drive components. Replacing a damaged fitting promptly restores full cooling capacity and protects the rest of the water delivery system.
