Bottom Vacuum Chamber & Wax Pot O-Ring for Yasui Vacuum Wax Injectors

This 100 mm bottom O-ring is a critical sealing component for the lower pressure chamber of Yasui Vacuum Wax Injectors. It is manufactured from high-grade, heat-resistant rubber to maintain a perfect seal under both vacuum and pressure conditions. Without a secure 100 mm seal, the machine cannot achieve the atmospheric consistency required for high-detail jewelry molds. This is a genuine replacement part designed for a precise fit and long-term durability.
