I have a 5qt older IP & gasket wore out. Couldn’t find OEM gaskets so bought a set of 2 off Amazon. Despite seating gasket in lid many times my IP starts to come up to pressure then blows & scares me. Anyone have that issue? Gaskets had great reviews & are correct size for my ip. I’d really like to use my ip. Any help appreciated. TIA.
