50332 3-Piece Pressure Regulator 5-10-15lb for Presto Pressure Cooker 0171001 0174001 6803571

Works the way it should.

Works fine, multiple weights, still using.

I bought this because I suspected the gauge on my Presto Canner was NOT accurate. I tested the Weight against the gauge and these were my results:WEIGHT at 5 pounds:GAUGE registered 9 pounds.RESULT: If I trust ONLY the gauge for a 5 pound reading, in reality, it will be reading 4 pounds lower, which would be only be at 1 pound of pressure - unacceptable for canning in the kill zone for bacteria.WEIGHT at 10 pounds:GAUGE registered 13 pounds.RESULT: If I trust ONLY the gauge for a 10 pound reading, in reality, it will be reading 3 pounds lower, which would only be at 7 pounds of pressure - unacceptable for canning in the kill zone for bacteria.WEIGHT at 15 pounds:GAUGE registered 17 pounds.RESULT: If I trust ONLY the gauge for a 15 pound reading, in reality, since it will be reading 2 pounds lower, this would really be at 13 pound of pressure - unacceptable for canning in the kill zone for bacteria.The gauge on my Presto Canner, just as I suspected was not accurate, which is what was causing my jars to be sealed when I took them out of the canner - and a few months later the contents would go bad due to not high enough temperature in the jar. So...I ended up dumping out of lot of the stuff I canned (especially recipes with meat such as soup and chili), which was a lot of work and expense, for nothing.These are my results and may not be yours... but how will YOU be able to tell if your gauge is accurately showing you that you have the correct pressure to preserve your canned foods, safely?I'm glad I bought the weight.BONUS... I no longer have to babysit this canner watching the gauge for the full canning time to make sure the pressure doesn't drop. My jars seal perfectly and so far, they are staying perfect.

Fits, perfectly. So glad I found this here on Amazon!

I am new to pressure canning, and my husband got me the 23 quart Presto pressure canner for our anniversary. I was having a difficult time with the pressure gauge and the regulator that came with it, so I replaced the factory regulator with this one and it has made canning EFFORTLESS! I felt confident with it the second time around and barely had to watch it. I was struggling to keep it at 10-11 psi needed for my elevation and recipes and with this it’s amazing!

This has helped me soooo much in putting up food works perfect

Worked fine

I think this is the original manufacturer and you can tell. Solid construction. Works perfectly.
