The Husqvarna 531118159 Nipple is a genuine OEM component designed for the DM406 concrete core drill. Sourced directly from Husqvarna, this fitting is manufactured to the exact specifications required for a secure, leak-free connection in the DM406 drill motor system. DHS Equipment supplies this part to help keep your core drilling equipment running at full capability.
Key Features
- OEM-Spec Thread and Dimensional Accuracy — manufactured to Husqvarna's exact tolerancing, ensuring proper thread engagement and a pressure-rated seal suited to the DM406's hydraulic or fluid circuit demands.
- Drop-In Replacement — matches the original fitting's thread form, length, and port size so it installs directly into the designated connection point with no machining or adaptation.
- DM406 Core Drill Compatibility — verified fitment for the DM406 concrete core drill, eliminating guesswork when ordering replacement hardware for this drill motor.
- Restored Flow and Connection Integrity — a correctly fitted nipple maintains consistent fluid or air flow through the circuit; a damaged or cross-threaded fitting can cause pressure loss, leaks, or downtime during core drilling operations.
A nipple is a short threaded fitting that joins two sections of pipe, hose, or port connections within a machine's fluid or pneumatic circuit. In the DM406 core drill, this fitting plays a critical role in maintaining a sealed, pressure-stable pathway — whether carrying water for cooling and flush, hydraulic fluid, or air. When the fitting is worn, cracked, or cross-threaded, the resulting leak can compromise drilling performance, cause fluid loss, or prevent the system from reaching the operating pressure needed for efficient core drilling. Replacing it with a genuine OEM part restores the connection to its original specification.
