my presto stainless steel pressure cooker is leaking from the lid, what part do i need?

Diagnosis

The most common cause of a leak from the lid of your Presto 01362 cooker is a degraded, damaged, or incorrectly seated sealing ring (gasket). Over time and with regular use, the silicone ring loses its elasticity, becomes brittle, or gets tiny nicks, preventing it from forming an airtight seal against the lid's inner groove. Before ordering a part, rule out simple issues like food debris on the ring or rim, or the ring being twisted or popped out of its channel.

How to Fix It

To resolve the leak, follow these steps:

1. Unplug the cooker and ensure all pressure is fully released and the unit is cool.
2. Remove the lid and take out the current sealing ring from its groove. Wash the ring and the lid's groove thoroughly with warm, soapy water to remove any grease or particles.
3. Inspect the ring for cracks, cuts, permanent flat spots, or stiffness. If it shows any wear, it needs replacement.
4. The correct part is the Presto replacement sealing ring, model number 09936. This ring is compatible with both the 4-quart and 6-quart stainless steel models like yours.
5. Before installing the new ring, lightly coat it with a thin film of vegetable oil. This helps it seat properly and extends its life.
6. Press the new ring firmly and evenly into the lid's groove, ensuring it is not twisted and is fully seated all the way around.

If That Didn't Work

If a new, properly installed sealing ring does not stop the leak, inspect other components. Check the lid's overpressure plug (the rubber stopper on top) for damage—it's part number 50048. Also, ensure the steam vent/weight regulator (the black nozzle and weight) is completely clean and unobstructed. Finally, examine the cooker's rim for any deep dents or warping that could prevent the lid from sealing evenly.

Heads Up

Never operate the pressure cooker if it is leaking steam continuously from the lid during the pressurization phase. This indicates a failed seal and means the cooker cannot reach or maintain proper pressure, which is a safety hazard and will not cook food correctly. Always replace sealing rings proactively every 12-18 months with regular use.
