Choosing a replacement gasket usually comes down to one question: does it fit the exact pressure cooker, canner, coffee maker, or truck reservoir you already own? These four gaskets are not interchangeable, and they sit at very different price points, so the right fit matters more than the number on the tag.
Quick Take
If you need a pressure cooker seal, the Pressure Cooker Sealing Ring Replacement Gasket is the straightforward daily-use option. If you own a Mirro canner, the Replacement Gasket for Mirro Pressure Canner is the model-targeted option. If you have a Sunbeam Coffee Master, the Replacement Gasket Seat Ring is the dedicated fit. And if you work on heavy trucks, the Automann 575.1078.2 Power Steering Reservoir Replacement Gasket is the low-cost, specific match.

Product Notes
Pressure Cooker Sealing Ring Replacement Gasket
For a simple pressure-cooker refresh, the $13.12 Pressure Cooker Sealing Ring Replacement Gasket is an easy first choice. It is made from food-grade silicone with heat resistance, and its main job is keeping the cooker airtight. It is also portable, which makes it easy to store or carry when space is tight. The size is optional, so you need to confirm the ring matches your cooker before committing. If you just want a modestly priced silicone seal for daily cooking, this one is a practical way to get back to normal.
Replacement Gasket for Mirro Pressure Canner, Compatible with 12/16/22QT Models
Mirro owners get a more targeted option with the $17.89 Replacement Gasket for Mirro Pressure Canner. It fits M-0512, M-0522, M-0312, M-0406, M-0416, M-0526 and M-0622, and the gasket is about 12.6 inches in diameter. It comes as the gasket only, in a matte black finish, and it is designed to create a high-efficiency seal for 12, 16, and 22 quart canners. The limitation is the model range: this is not a universal ring, so your canner needs to fall into that Mirro group. That focus is also what makes it a clean replacement for the right owner.
Replacement Gasket Seat Ring For Sunbeam Coffee Master Model C30 C30A C30B C30C
The priciest part in this group is the $49.99 Replacement Gasket Seat Ring for Sunbeam Coffee Master. It fits C30, C30A, C30B and C30C models, and installation is simple: move your existing metal spring "comb" insert into the new gasket, then drop the ring into place with no tools. The silicone construction is heat resistant, and the part carries a one-year warranty. What keeps it from being a complete repair kit is the metal spring insert, which you must reuse from the old gasket. If that insert is still in good shape, this is a direct fit for a Coffee Master.
Automann 575.1078.2 Power Steering Reservoir Replacement Gasket Ref# FGQ79699
At the other end of the price range, the Automann 575.1078.2 Power Steering Reservoir Replacement Gasket sells for $4.95 and is easy to cross-check. It fits Kenworth T660 and Peterbilt 379 applications, and the OEM part numbers NMCQ79699, Q79699 and FGQ79699 give you something to compare against the part you already have. It also appears in Automann service kits for these reservoirs, which makes it a purpose-built part rather than a generic sheet. It is not a universal-fit part, so you need a matching reservoir application. For the right truck, this is a low-price, exact-match gasket.
Final Recommendation by Use Case
Reach for the Pressure Cooker Sealing Ring Replacement Gasket when you want a simple seal for daily cooking. Opt for the Replacement Gasket for Mirro Pressure Canner when your canner matches the Mirro models in this comparison. The Replacement Gasket Seat Ring for Sunbeam Coffee Master is the dedicated fit for that coffee maker line. And the Automann 575.1078.2 Power Steering Reservoir Replacement Gasket works well when your heavy-truck application matches the reservoir part number.
