When it may not be suitable

This gasket is designed for pressure cookers with a 3.5 L capacity and a 17.5 cm lid diameter; it may not fit pressure cookers of different sizes or lids with a nonstandard profile. If the cooker manufacturer specifies a different gasket shape or material, using a non-specified seal could affect performance or safety. Verify fit and compatibility before installation.

Key specifications

• Material: heat-resistant silicone
• Intended pot capacity: 3.5 litres
• Lid diameter compatibility: approximately 17.5 cm
• Function: airtight sealing ring for pressure retention
• Cleaning: washable with warm soapy water

How to use

Ensure the pressure cooker is cool and not under pressure before attempting replacement. Remove the old gasket from the lid groove, clean the lid sealing area of food residue and debris, and inspect the lid for damage. Fit the new silicone gasket into the groove, seating it evenly all the way around. After installation, perform a short test run with water to confirm there are no steam leaks and that the cooker reaches operating pressure. Follow the pressure cooker manufacturer’s safety instructions during testing and normal use.

What to consider before purchase

• Confirm your pressure cooker has a 3.5 L capacity and a lid diameter of about 17.5 cm
• Check that the lid groove profile matches a circular silicone ring-style gasket
• Ensure heat-resistant silicone is an acceptable material according to your cooker’s manufacturer
• Inspect the lid for warping or damage that a new gasket alone would not correct

Usage recommendations

Regularly inspect the gasket for hardening, cracking, or deformation and replace it when signs of wear appear. Clean the gasket and lid sealing area after each use, avoid sharp tools that could nick the silicone, and store the gasket away from direct sunlight or high heat when removed. When testing after installation, use only water and never force the cooker closed or operate it with visible leaks.
