Key Features
- OEM-Spec Threading — Manufactured to Husqvarna's exact 3/8 thread specification, ensuring a proper seal and full hydraulic pressure integrity at the connection point.
- Direct Hydraulic Connection — Engineered to thread directly into the designated port on compatible Husqvarna power packs and compactors with no reworking of the fitting seat required.
- Broad Fitment Coverage — Compatible with PP440, PP440HF, PP480, PP480HF, and PP492 power packs, as well as the RC455 compactor, covering a wide range of Husqvarna construction equipment.
- Leak-Free Hydraulic Integrity — A correctly seated nipple maintains consistent hydraulic flow to downstream tools; a worn or damaged fitting can cause pressure loss and contamination of the hydraulic circuit.
- Genuine OEM Confidence — Sourced directly from Husqvarna's OEM supply chain, this fitting meets the same material and dimensional standards as the original component installed at the factory.
A hydraulic nipple serves as a threaded connector that joins hydraulic lines or ports within the power pack's fluid circuit, allowing pressurized fluid to pass between components without leakage. In a high-frequency or hydraulic power pack like the PP440HF or PP480HF, maintaining a fully sealed hydraulic circuit is critical — even a minor fitting failure can result in pressure drop, fluid loss, or damage to connected tooling. Replacing a damaged or corroded nipple with the correct OEM part restores the integrity of the hydraulic connection and ensures the power pack continues to deliver consistent output to the tools it drives.
