Customized Double Cylinder Sapphire Crystal Watch Glass for Wristwatch Parts Why Choose sapphire crystal? Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm Sapphire crystal is extremely hard and scratch resistant. It is the hardest of the oxide crystals, being the next strongest material to diamond. Because of its hardness (second only to Diamond), Sapphires are used in industrial applications such as components for watch crystals and movement bearings, scientific instruments, high-durability windows, and insulating substrates in special purpose solid state electronics Sapphire is grown using a variety of methods. Standard grade Sapphire material is grown by Verneuil and Czochralski methods, whereas higher quality Sapphire is manufactured by the Kyropulus growth method. Sapphire is able to be cut thinner than alternative crystals due to its structural durability.

An  O-ring , also known as a packing, or a  toric joint , is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. 	 Material: Rubber NBR / PVC 	 Diamater: 0.3, 0.4, 0.5, 0.6, 0.7, 0.8mm 	 Length: 10mm to 35mm 	 Packing: 1,000pcs per polybag with label 	 Qty: Stock on hand on some size   
5 Benefits : 	 O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable, and have simple mounting requirements. 	 They can seal tens of megapascals (thousands of psi) of pressure.
