This large vacuum chamber O-ring measures 189 mm in diameter with a thickness of 7 mm. It is designed to provide a gastight seal for the vacuum chambers of VC 200 through VC 600 casting machines.
The durable rubber material resists the heat and compression associated with repeated casting cycles. Maintaining a perfect seal is vital for achieving the deep vacuum necessary for high-quality jewelry casts. This O-ring should be inspected and lubricated regularly to ensure the continued performance of your casting machine.
