About this part
- Fits Butterfly Blueline steel 7.5 (low dome), 10, 12 litre
- Also fits the 4.5 litre senior pressure pan
- Senior 'U' size; black food-grade nitrile rubber
Butterfly's Senior 'U' gasket: the black nitrile rubber sealing ring for Butterfly Blueline stainless steel cookers of 7.5 litre (low dome), 10 and 12 litres, and for the 4.5 litre senior pressure pan. The pack says Senior 'U' and food-grade nitrile rubber.
The ring seats in the lid rim and keeps steam in while the cooker builds pressure. Change it when steam escapes under the lid, the whistle comes much later than it used to, or the rubber has gone hard, cracked or stretched.
Check before you order: the 3.5, 4.5 and 5 litre Blueline take the Junior 'U', and the 2 and 3 litre the Sub Junior 'U'. Butterfly also makes the Senior 'U' in green silicone. Big aluminium Standard cookers take the Senior 'R'.
A gasket is a wear part with a service life. Once it hardens or flattens it stops sealing, and on a pressure cooker that means steam escaping around the rim instead of building pressure.

Rather we fitted it?
This is a part we fit rather than sell as a do-it-yourself job. Book a pressure cooker visit and the technician arrives with it, tests the appliance, and closes the job only once you confirm the work.

Cooker Gasket Butterfly Senior U Nitrile Rubber — questions we get asked
How much is the Cooker Gasket Butterfly Senior U Nitrile Rubber?
₹125, and that is what you pay — the amount is restated before you confirm and nobody re-prices it after opening the appliance. Fitting, if you want it, is quoted separately and agreed first.
Will it fit my pressure cooker?
Gasket size follows the cooker litre capacity, not the brand alone. Check the number stamped on the base of your cooker before you order. WhatsApp a photo of the appliance and of the failed part, and we will confirm the match before you pay for anything.
Can I fit this gasket myself?
We do not supply it that way. A gasket is a wear part with a service life. Once it hardens or flattens it stops sealing, and on a pressure cooker that means steam escaping around the rim instead of building pressure. A technician brings it, fits it, tests the appliance, and you sign the job off before it is billed.
How soon can I have it in Bangalore?
It is in stock in Bengaluru. Parts we hold locally usually reach a job the same day, and most repairs booked against them close within 12 hours across the city.
Can I get a GST invoice?
Yes. This part invoices under HSN 4016, and a GST invoice is raised for the order — which is what a technician or a dealer buying for a workshop needs.
