"Presto Pressure Cooker sealing ring" 2010-03-09By
Svetlana Glazyrina (Boston, MA United States)
I have 2 year old pressure cooker and gradually it started cooking worse and worse. i thought I needed to buy a new one but then read documentation for my cooker saying that sealing ring and overpressure plug should be replaced every 2 years.
So I bought that, replaced these details which was very easy and cooker working as new.
Great fix for the little money!!!

The cooker is doing a lot better after the gasket/ sealing ring was replaced. Product arrived on time in good condition.

M. MalottWe thought our lid might have gotten warped so we originally bought an aftermarket and it did not work properly. Bought this factory original and now it works perfectly

My pressure cooker failed to properly seal and retain pressure. I loved the pressure cooker for quick meals and great pot roast. I debated buying a new one until I discovered a great repair kit available on Amazon. The gasket was easy to install and fit perfectly. A relief button was also included and now the cooker works like new. I would recommend this for anyone who has a Presto Pressure cooker that's done as much cooking as mine.

This was a replacement for my old pressure cooker seal which started to leak. Product arrived in a timely manner and worked as advertised. Also came with a rubber pressure relief valve which I've kept as a spare.
