High Pressure Industrial PU O Ring Max -50 Elongation For Hydraulic
Seal
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 (FKM, 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
