Sealing Applications 


Static Sealing in which there is little or no relative motion between the mating surfaces: and Dynamic Sealing which must function between surfaces with definite relative motion, such as seal on the piston or hydraulic cylinder. Of the two types, dynamic sealing is the more difficult and requires more critical design work and materials selection. O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, quality, quantity and cost.

Standard O-rings are made from a variety of rubber compounds and compression molded into the shape of an O-Ring. Base polymers include polyacrylate (ACM), ethylene acrylate (AEM), butyl rubber (Isoprene, IIR), polychloroprene rubber (Neoprene), ethylene propylene rubber (EPM, EPDM), fluorosilicone, acrylonitriles-butadiene (Nitrile, NBR), hydrogenated nitrile (HNBR), polyurethane (AU), silicone, fluorocarbon (Viton, FKM), tetrafluoroethylene propylene (Aflas), high performance fluoroelastomers (Hifluor), and perfluorinated elastomer (Parofluor and Parofluor ULTRA).

Industry standard O-Ring sizes in accordance with AS 568 dimensions are available or custom O-Rings of practically any dimension can be made to fit an application. Miniature o-rings, large special o-rings, continuously molded and spliced cord are just a few examples of the custom o-ring possibilities.

 

Competitive Advantage:

 

1) have all AS568 ,Metric and well used series o ring mould,and parts of other standards

2) work with buyers worldwide more than 10 years in rubber solution.

3) high quality with best price

4) All material can pass FDA test and also have FDA certification

5) OEM parts mold cost can be return back once your Quantity can reach our requirements.

6) a very special manufacture in industry for rubber and silicone products
