Trusted by the team at Australian Jewellers Supplies, they’re suited for use across all types of jewellery crafting.

Frequently Asked Questions:

1. What size flasks are compatible with my casting machine?

Most machines support standard flask sizes (e.g., 3"x5" or 4"x6"), but always check the machine specs or speak with your casting supplier to confirm fit.

2. How often should I replace casting gaskets?

Replace gaskets when they show signs of wear, loss of flexibility, or reduced seal performance—typically every few months with regular use.
