YD-100 Large Square Silicone Gasket Lid

Heavy-duty square tempered glass lid with an 8 mm ultra-narrow food-grade silicone rim, . Engineered for pressure cookers and electric multi-cookers, the silicone gasket delivers a tight steam seal while absorbing thermal shock, keeping the glass intact through repeated high-heat cycles. FDA & LFGB compliant and fully OEM/ODM customizable.

Key Advantages

• 8 mm narrow silicone rim — 2 mm slimmer than conventional 10 mm seals, giving a flush modern fit and lower material cost.
• Tight steam seal — the food-grade gasket locks in steam and pressure, ideal for multi-cookers and stockpots.
• Thermal-shock resistant — tempered soda-lime glass survives rapid temperature change and breaks safely if ever overstressed.
• Built for OEM — laser-etched logos, custom vent positions and custom rim colors available.

Specifications

Where It's Used

This square silicone-rim lid is purpose-built for electric pressure cookers, multi-cookers and square stockpots. The narrow rim hugs thin-walled modern cookware without overhang — a clean fit for private-label appliance brands and replacement-part programs.

Why the Narrow Rim Matters

Traditional silicone seals use a bulky 10 mm rim that overhangs on today's slim cookware. Our 8 mm profile sits flush for a sleeker look, uses less material (lowering your unit cost), and still maintains a full steam-tight seal.
