Key Features
- Genuine OEM Galvanized Construction — Manufactured from galvanized steel to Husqvarna's corrosion-resistance specifications, ensuring the fitting stands up to the wet-cutting environments common on floor saw operations.
- Exact 1/2" Thread Specification — Threaded to the correct 1/2" pipe standard so this fitting connects directly to the existing plumbing ports without thread chasing or adapter hardware.
- Broad Floor Saw Compatibility — Fits the FS4800D, FS6600D, FS6800D, FS8400D, Pro65G, and RS8500D floor saws, covering a wide range of Husqvarna's walk-behind flat saw lineup.
- Leak-Free Fluid Circuit Integrity — A correctly seated close nipple maintains steady water flow to the blade, which is essential for effective cooling and dust suppression during concrete and asphalt cutting.
- Verified OEM Part Number — Cross-reference 539300243 against your machine's parts diagram to confirm the correct position and application before installation.
A pipe close nipple is a short, fully threaded pipe fitting used to join two threaded components with minimal gap between them — essentially a tight, rigid pipe-to-pipe or pipe-to-port connection. In a floor saw's water delivery system, this fitting helps maintain consistent flow to the blade guard and cutting zone for cooling and slurry management. A damaged, corroded, or cross-threaded nipple can result in water leaks, reduced blade cooling, and increased dust exposure at the cut, making a prompt like-for-like replacement important for both machine performance and on-site safety.
