Gasket for Presto Pressure Cookers

The white-and-grey marble sealing ring is made for Presto pressure cookers and canners. It sits inside the cover and creates a pressure-tight seal between the lid and the body during cooking. The part fits 3-4 quart models and replaces a worn or damaged original gasket. Compatible model numbers include 703, 733, B301A, B301B, 704, 744, B401A, and B401B.

Replaces the original sealing ring

This gasket takes the place of the factory seal when it stretches, cracks, or no longer holds pressure. The jump is worth it when steam leaks around the lid or the cooker fails to reach pressure. It restores the airtight fit required for safe pressure cooking and canning. Not suited for larger-capacity Presto units or other brands.

Holds seal under sustained pressure

During long processing times the ring maintains its shape and keeps the cover locked to the body. It resists the repeated heat cycles of canning sessions without permanent deformation. The material stays pliable so the lid seats cleanly each use. Not designed for continuous industrial autoclave duty.
