Pressure cookers: the size, the settings and the seal

A pressure cooker is the one piece of cookware that is also safety equipment. Three things decide a good one: a capacity that suits your cooking, settings published as something you can understand, and a seal you can still buy in five years. Everything else is convenience.

Five cookers, and the three questions that separate them.

The one that publishes its temperatures

The WMF 4.5 liter, Ø 22 cm (8.7 in), 18.3 cm (7.2 in) high, with two settings at 110 °C (230 °F) and 119 °C (246 °F) and a large cooking signal. Publishing the settings as temperatures rather than symbols is the clearest specification in this hub.

The one with the longest durability claim

The Tefal 6 liter, 22 cm (8.7 in), 18/10 stainless, two cooking settings, and stated tested to a thirty-year life. That is the longest such claim anywhere in this catalog.

The one that publishes its metal

The Elo 18 cm (7.1 in), 18/10 stainless, with a 1.0 mm (0.04 in) wall and a 5.0 mm (0.20 in) total base, and automatic pressure regulation. Wall and base thickness published together is rare, and the base is what stops food catching under pressure.

The one with a basket included

The Falkenstein 6 liter, with a Quickturn lid mechanism, a cooking signal and a steaming basket included. The basket is what makes a pressure cooker also a steamer.

The one built around its valve

The Hawkins, stainless, with a shielded safety valve and a pressure-locked safety lid. A pressure-locked lid cannot be opened while there is pressure inside, which is the mechanism that matters most.

Before you buy any of them

Find the replacement seal for that model and check it is still sold. A cooker whose seal has been discontinued is a pot.

Which pan does your cooking want?

You cook pulses and tough cuts
This is where a pressure cooker genuinely changes the kitchen.
You want it to do everything
An electric multicooker, with the compromises that brings.
You want speed and control
A stovetop model, which reaches pressure faster.
You are nervous about them
Modern models have several independent safety systems.

Picking by what you cook

Pulses and grains

The clearest gain: dried beans and chickpeas without an overnight plan.

Tough cuts

Where long braising is compressed into a fraction of the time.

Stock

Where pressure extracts quickly and produces a clear result.

Everyday cooking

Where an electric model doubling as a slow cooker earns its worktop space.

What makes the difference in use

Stovetop or electric
Stovetop reaches pressure faster and gives more control. Electric is programmable and does more jobs less brilliantly.
Capacity
Pressure cookers cannot be filled to the top, so usable volume is well below stated capacity.
Safety systems
Modern cookers have several independent mechanisms. Understanding them is part of using one confidently.
Seal availability
The gasket is a wearing part. A cooker whose seals you cannot buy is a cooker with a fixed life.
Ease of cleaning
Lids and valves need proper cleaning. A design that makes that awkward gets neglected.

Where it usually goes wrong

Overfilling
Pressure cookers have a maximum fill line for good reason, and it is lower than people expect. Follow it exactly.
Forcing the lid
A lid that will not open still has pressure inside. Release it as the instructions direct and never force it.
Neglecting the valve
A blocked valve is a genuine hazard. Cleaning it is part of every use, not an occasional job.
Ignoring the gasket
It perishes and stops sealing. Replacing it is routine maintenance, not a repair.

By the cook you are

The pulse cook
Gets the most from it, since dried beans stop needing planning.
The busy household
Often prefers an electric model that can be set and left.
The traditional cook
Chooses stovetop for speed and control, and accepts the attention it needs.

Care, seasoning and how long it lasts

A pressure cooker is one of the few kitchen items where maintenance is a safety matter rather than a longevity one. The gasket perishes, the valve blocks, and both failures are gradual and invisible until the cooker either will not seal or will not vent.

  • Clean the valve and lid thoroughly after every use.
  • Inspect the gasket regularly and replace it when it hardens or cracks.
  • Check that all safety mechanisms move freely.
  • Follow the manufacturer’s instructions exactly; they are specific to the model.

Safety

This is the one piece of cookware where the manual matters.

  • Read and follow the manufacturer’s instructions for your specific model.
  • Never exceed the maximum fill line.
  • Never force the lid; release pressure as the instructions direct.
  • Keep the valve clean and unobstructed at all times.

The questions that come in

What size do I need?

A pressure cooker is filled to two-thirds at most, and less for anything that foams. A 4.5 liter cooker is a three liter meal; six liters feeds four or five comfortably.

How often does the seal need replacing?

Makers commonly say every one to two years, or as soon as it hardens, cracks or stops sealing. Check that a replacement seal is available for your model before you buy the cooker — this site lists seals for WMF, Silit, Fissler and Tefal.

Why do published temperatures matter?

Because "setting 1" and "setting 2" tell you nothing. The WMF here publishes 110 °C (230 °F) and 119 °C (246 °F), which is the difference between gentle cooking and the fast setting, expressed as something you can reason about.

Stovetop or electric?

Stovetop reaches pressure faster and gives more control; electric is programmable and can be left. It depends on how you cook.

Are pressure cookers safe?

Modern models have several independent safety systems. The manufacturer’s instructions for your model are the thing to follow.

How much can I put in?

Never above the maximum fill line, which is lower than most people expect. It is a safety limit, not a suggestion.

What maintenance does it need?

Cleaning the valve after every use and replacing the gasket when it hardens. Both are safety matters rather than longevity ones.

What is it best at?

Pulses and tough cuts. Dried beans without soaking overnight is the change most people notice first.

Is a multicooker a good pressure cooker?

It does the job alongside several others, generally less quickly than a dedicated stovetop model. That trade is the whole question.

Short answer first

What is behind this list

The pans here are drawn from the catalog of this site. Specifications come from the maker and from the Amazon product page; prices are what Keepa recorded on the date below, and both move. Order is set by declared specifications, by stated strengths against stated limits, and by price. Nothing here has been cooked with by us, and no claim to the contrary is made.
