1Pcs Food Grade TM31 Sealing Ring Replacement Durable Large Lid Gasket Accessory for Home Cooking

### Product Description This dual composite rubber sealing O-ring delivers reliable leak-proof performance for industrial, automotive and plumbing sealing applications, with extended service life and strong adaptability to diverse working conditions. #### Key Features: 1. Dual-Material Composite Build: Made of outer black nitrile rubber (NBR) and inner green polyurethane (PU), it combines NBR's excellent oil resistance and PU's ultra-high wear resistance. It has 35% longer overall service life than single-material sealing rings, effectively cutting down users' replacement costs. 2. Superior Oil & Corrosion Resistance: The high-purity NBR outer layer effectively resists corrosion from lubricating oil, hydraulic oil, water and mild chemical reagents, prevents material aging and cracking caused by medium erosion, and reduces equipment maintenance frequency. 3. Wide Temperature Adaptability: Made of high-performance elastic rubber composite, it maintains stable elasticity and sealing performance in the temperature range of -40℃ to 120℃, does not harden at low temperature or deform at high temperature, and adapts to various complex working environments. 4. Precision Molding Craft: Adopts one-piece high-precision injection molding process, with smooth burr-free edges and accurate size, fits tightly with the installation groove, effectively prevents leakage of liquid, gas and dust, and ensures stable operation of connected equipment. 5. Excellent Compression Resilience: The high-elastic polyurethane inner layer quickly returns to original shape after long-term heavy compression, avoids permanent deformation that causes sealing gaps, and maintains long-lasting reliable sealing effect after repeated use. #### Specifications: Category: Sealing O-Ring / Mechanical Sealing Accessory Material: Nitrile Rubber (NBR) + Polyurethane (PU) Composite Size: 18.5*18.5*1.2cm Color: As shown in the picture Quantity: 1 piece #### Notes: 1.
