Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's exact material and dimensional standards, ensuring the correct thread form, wall thickness, and sealing integrity expected of a fluid or air passage fitting.
- Drop-In Replacement — Engineered to match the original mounting interface, allowing this nipple to seat and seal correctly without rework or adapter hardware.
- Broad K-Series Compatibility — Fits the K770, K970, K4000, K3000, K1PACE, K540i, and K535i power cutters, covering a wide range of Husqvarna's professional handheld cutting lineup.
- Maintains Flow Integrity — A correctly fitted nipple keeps fluid or air routed through the intended circuit; a damaged or worn nipple can cause leaks, pressure loss, or contamination that degrades cutting performance.
- Verified Part Number — Ordering by part number this part ensures you receive the exact component specified for your machine, eliminating the guesswork of cross-referencing generic fittings.
A nipple is a short threaded fitting that connects two sections of a fluid or air line within the machine, maintaining a leak-free passage between components. It plays a quiet but critical role in keeping the correct pressure and flow moving through the system — whether that system handles water, hydraulic fluid, or air. When a nipple cracks, corrodes, or strips at the threads, the resulting leak or blockage can cause erratic machine behavior, reduced output, or damage to connected components, making timely replacement essential for consistent performance.
