Key Features
- OEM-Grade Seal Material — Manufactured to Husqvarna's compression and material specifications, ensuring the gearhouse seal seats and retains properly under the operating conditions of the DM220 drill motor.
- Direct Drop-In Replacement — Engineered to the same profile and dimensions as the original, this seal installs into the gearhouse without any modification to the surrounding assembly.
- Confirmed Fit for the DM220 — Specifically designed for the DM220 concrete core drill, a professional-grade drill motor used in demanding core drilling applications.
- Preserves Gearhouse Integrity — A correctly seated seal prevents lubricant loss from the gearhouse and keeps contaminants out, maintaining smooth gear operation and protecting internal components from accelerated wear.
- Genuine Husqvarna OEM Part — Backed by Husqvarna's OEM quality assurance, this seal delivers the fit and performance expected from original equipment components — not an approximation.
The gearhouse seal on a core drill motor serves as the barrier between the internal gear lubrication and the outside environment. It prevents gear oil or grease from escaping the gearhouse while also blocking water, slurry, and concrete dust from entering during wet core drilling operations. When this seal deteriorates or fails, lubricant loss leads to increased friction and heat within the gearhouse, and contamination from drilling slurry can cause rapid wear to the gear train. Replacing a worn seal promptly with the correct OEM part restores the integrity of the gearhouse and protects the more costly components inside.
