Seals, gaskets, and O-rings are small components, but when one wears out, you notice the leak right away. The key is choosing the right replacement for the specific machine you own. Here we compare two new gaskets: a Replacement Gasket Seat Ring for Sunbeam Coffee Master models C30, C30A, C30B, and C30C, and a Market Forge Steam-It Door Gasket 10-2666. With an $18 price gap between them, the right choice depends on what you're repairing.
Quick verdict
If you're repairing a Sunbeam Coffee Master vacuum coffee maker, the Replacement Gasket Seat Ring is the one you need. It installs without modifications. If you're servicing a Market Forge Steam-It unit, the Door Gasket 10-2666 is the proper replacement.

Product notes
Replacement Gasket Seat Ring For Sunbeam Coffee Master Model C30 C30A C30B C30C
This gasket seat ring is built for Sunbeam Coffee Master vacuum coffee makers in the C30 series. It's made of food-grade silicone, which gives it good heat resistance and a long service life. Installation is straightforward: you transfer the metal spring "comb" insert from your existing gasket into the new ring, then drop the whole thing into place. No tools or modifications are needed. At $49.99, it's the more affordable option here. One thing to note: the spring comb insert is not included, so you'll need to keep the one you already have. Another limitation is that it's designed specifically for the C30, C30A, C30B, and C30C models, so if your Sunbeam isn't one of those, this isn't the right part.
Market Forge Steam-It Door Gasket 10-2666 - Genuine OEM Replacement Part
This is a genuine OEM replacement part from Market Forge, specifically the Steam-It door gasket with part number 10-2666. It's manufactured in the United States and comes with a UPC, so it's easy to confirm you're getting the factory-specified part. At $68.11, it's clearly positioned for buyers who want an original component rather than an aftermarket alternative. The main limitation is the price: it costs $18 more than the Sunbeam gasket, and the higher price is worth it only if you actually own a Market Forge Steam-It unit. If your equipment is from a different manufacturer, this gasket won't help you. But for a Market Forge owner, a genuine OEM gasket gives peace of mind that the seal is built to the original specification.
Final choice by use case
If you're restoring a Sunbeam Coffee Master vacuum coffee maker, go with the Replacement Gasket Seat Ring; it's the correct fit and the more affordable option. If you're maintaining a Market Forge Steam-It, the Door Gasket 10-2666 is the genuine OEM part worth the higher price. Match the gasket to the machine and you're set.
