The Ultimaker Hard Seals for the Material Station are original spare parts that seal the filament exit passages in the Material Station housing. The Material Station is designed to maintain a low-humidity internal environment to protect hygroscopic filaments, and the hard seals around the filament exit paths are critical to preventing atmospheric moisture from entering the station and compromising this dry environment.

Over time, these seals can degrade, harden, or crack, reducing their sealing effectiveness and allowing moisture ingress. Replacing them with genuine Ultimaker hard seals restores the airtight filament passage and maintains the Material Station's active moisture protection for PA, PC, TPU, and other moisture-sensitive materials.

Key features

• Original Ultimaker spare seals for the filament exit passages in the Material Station housing.
• Maintains the airtight seal needed to preserve the low-humidity internal environment of the Material Station.
• Prevents moisture ingress through filament passages that can degrade hygroscopic filaments stored inside.
• Direct replacement when seals show cracking, hardening, or reduced sealing effectiveness.
• Essential for the long-term performance of the Material Station's moisture management system.
