D Hollow Silicone Seal Strip High Temp Gasket for Vacuum Sealer Centrifuge

Our D-shaped hollow silicone seal strip is a professional replacement sealing gasket for vacuum sealers, lab centrifuges, drying ovens and industrial mechanical cabinets. Crafted from high-density transparent silicone, this half-round hollow strip features premium heat resistance, oxidation resistance and shock-absorbing anti-collision performance.The hollow D profile enhances compression resilience. When fitted into machine door grooves, the silicone gasket eliminates air leakage, stabilizes vacuum pressure, reduces running vibration and buffers impact during equipment opening and closing.This heat-resistant silicone sealing strip can be cut to any custom size to match all standard and custom machinery. Simple slot installation requires no professional tools for quick replacement of worn old gaskets. Widely used as universal spare sealing parts in food processing plants, medical laboratories and mechanical workshops.
