P45007, or P4507

Bullet one: “Replacement parts for P45007 T-fal Clipso Pressure cooker.” The description: “…for T-fal P4507 Clipso stainless steel pressure cooker.”

Five digits against four, and nothing on the page resolves it. The two numbers are not the same product.

On a listing whose entire value is the model number, that is the defect that matters. A gasket is not a product you choose; it is a product you match.

What is consistent is the part number of the gasket itself. X9010501 appears in the title and the description, and the catalog reference is 32406058279. Quote the X9010501, not the cooker number.

And then do the thing that settles every ambiguity on this shelf: read the number off your own cooker — stamped on the body or printed under the base — and measure the groove inside the lid.

Three listings here have model information you cannot fully trust:

this — two different machine numbers Prestige Senior, $16.01 — three different capacity lists across its own title and bullets, with a bullet reading “Suitable for the Following” that names nothing Presto, $19.28 — three model codes (01260, 01340, 01360) and no other identification at all

And two that are safe:

Prestige Junior, $8.94 — says the same thing three times, and adds “Does not work with other brands or models” Hawkins, $7.33 — three named models plus the height class, “2-4 Liter Tall”

Silicone, which is the only one on this shelf

The title publishes it: “Silicone Replacement Gasket.”

The shelf, on material:

this — silicone Prestige Junior and Prestige Senior — “the best rubber”, “self compensating” Hawkins, Presto, T-fal Secure 5 — nothing stated

What silicone does better. It keeps its elasticity through far more heat cycles before it hardens — and hardening is the real end of a gasket’s life, because a ring that no longer deforms cannot fill the uneven gap between a lid and a body. The symptom is gradual: the cooker takes longer and longer to come up to pressure.

It also absorbs less, which matters for the thing the Prestige pages name and this one does not: “It does not impart any color, taste or odor to the food.” A rubber ring that has cooked spiced food for a year smells of it permanently. Silicone is better on that count by nature.

What rubber does better. It is more compliant cold, so it seals at the start of a cook with less pressure behind it; and it is cheaper. The Prestige Junior is the cheapest per gram on this shelf at about 20 cents, against 34 cents here.

And one argument comes from the cooker rather than the ring. This is the only listing on the shelf to name a stainless steel body. Stainless expands less than aluminum when heated, so the gap the gasket has to bridge changes less between cold and hot — which suits a slightly firmer material. The two Prestige rings and the Hawkins are all for aluminum cookers.

Seventy grams, and a rectangular footprint

70 g, which ties with the Prestige Senior for the heaviest published weight here.

The shelf: Hawkins 10 g (0.4 oz) (2–4 L) · Prestige Junior 44 g (1.6 oz) (4–6 L) · Presto 45 g (1.6 oz) (6 qt) · this 70 g (2.5 oz) · Prestige Senior 70 g (2.5 oz) (7.5–13 L) · T-fal Secure 5 not published.

Weight scales with cooker size across this shelf, so 70 grams puts this among the larger cookers — which is consistent with a Clipso, and is the only size clue the page offers, because no capacity is published anywhere. Every other listing here gives one: 2–4 liters, 4–6 liters, 6 quarts, 7.5–13 liters, 6.3 and 8.5 quarts.

And no diameter, which is the figure that would resolve everything.

The catalog footprint is 13.3 × 9.4 inches — rectangular, so it is the box rather than the ring laid flat. That reading can be checked against the one listing that publishes a diameter: the Prestige Senior states “10.5-Inch” and records a square 267 × 267 mm, which is 10.5 inches exactly. So square footprints on this shelf are flat rings and rectangular ones are boxes.

Which leaves the measurement to you. Lay a tape across the groove inside your lid, outer edge to outer edge. For reference, the Prestige rings work out at 9.0 and 10.5 inches.

Four bullets saying one thing

“T-fal replacement gaskets.” “Gasket - pressure cookers.” “T-fal pressure cooker parts.”

Three bullets out of five carry no information that the title does not already give. The fourth, “Strong Durability”, is a claim with no figure — and durability is the one property on a gasket that could be quantified and never is on this shelf.

Which leaves bullet one doing all the work, and bullet one is the one with the wrong number in it.

Compare how the Prestige Junior spends its five bullets: three on fitment (including the exclusion), one on being genuine, one on country of manufacture. Or the Hawkins: one on fitment, one on being genuine, one on origin and life, one on the three named models — plus a description that explains what the part does.

This page’s useful content is the title, the material, and the part number. Which, to be fair, is most of what you need — once the cooker number is settled.

“Easy to install” in the description is worth one note, because it is the only mention of fitting on this shelf. A gasket must go in round. It is deliberately slightly too large in section for its groove — that is how it seals — so fitting means working it round the groove in stages rather than pulling one side home and stretching the rest. A ring fitted stretched sits out of round and leaks at the thin point.

What is not published

No capacity, as above — the only listing on this shelf without one.

No diameter, as above.

No country of manufacture, where the two Prestige rings and the Hawkins all say “Made in India”. The Prestige Junior’s reference field is worth a glance for the same reason: it reads 8.90E+12, a thirteen-digit EAN read as a number, and the three surviving digits — 890 — are India’s GS1 prefix.

No replacement interval. Not at least one of the eight listings here publishes one, which on a wear part in a pressure vessel is the most consequential omission. The failure is gradual: a cooker that takes noticeably longer to come up to pressure than it did when new has a gasket that is finished. Cracks, flat spots and a glazed surface are the visual signs.

No dishwasher guidance. The Presto at $19.28 is the only listing on this shelf to address it, and its answer is “Is Dishwasher Safe No” — so hand-washing is the safe assumption on silicone too.

No storage advice, which follows from the second failure mode: a ring left compressed in a closed lid for months takes a permanent flat and then leaks there. Storing the lid inverted on the body costs nothing.

No genuine-part statement, where the Prestige Junior says “Genuine Prestige Gasket” and the Hawkins “Genuine Hawkins” — though a T-fal part number in the title carries much of the same weight.

No quantity, and a wear part is the obvious thing to buy two of.

No temperature or pressure rating, which nothing on this shelf publishes.
