【Precise Compatibility】Specifically customized for Weston Pro-2100 (65-0101), Pro-2200 (65-0401-W) and Pro-2300 (65-0201), it perfectly fits 08-0501-W. It includes 2 oval vacuum chamber seals and 2 pieces of Teflon tape (with dual specifications of 10mm and 15mm), which can solve problems such as air leakage and vacuum failure. 【Food-grade and Durable Material】The seals are made of highly elastic gaskets, and the tape has a food-grade Teflon coating. It is resistant to grease and oxidation, ensuring safety when in direct contact with food. 【Easy Installation】Please unplug the power switch before installation. The tape has pre-applied adhesive on the back and can be torn and pasted immediately. The slots of the seals can be precisely aligned, and no tools or technical expertise is required. 【Solve the Suction Problem】If your food sealer has difficulty maintaining a vacuum state during sealing, you may just need to replace the sealing ring! It is recommended to replace the sealing ring of the food sealer once a year. 【Fix the Seal】If your Weston Pro has trouble sealing bags, the heating element tape may be worn out and need to be replaced. However, this cannot repair a heating element that is completely out of order. Please refer to the product instructions for details.
