One, three yuan import O-ring of imported raw materials and main product categories
100% imported raw materials - the United States DuPont, Daikin, Germany LANXESS and other well-known companies to provide. High quality raw materials to ensure the sealing performance of the product. Taiwan Asahi Meike XOK sealing technology is dedicated to providing first-class imported seal of the company.
Main products:
O, A type ring: all kinds of rubber O ring, mainly has NBR, HNBR, FKM/VITON, EPDM, FFKM, SIL, PU, CR, PTFE, etc.;
B, ED ring, star ring, rubber gasket, rubber ball, flat ring, combination washer, pneumatic seals and non-standard pieces of rubber parts;
C, cylinder: spot with TC skeleton oil seal oil seal, the other also has production, such as Y - ring, U - ring, V composite, stepseal, glyd ring and a dustproof ring seal, etc.;
Two or three import O-ring series standard and line diameter of EPDM
O type circle is a standard part, the application is very extensive, in the process of development gradually formed the standard of each country.
There are several representative of the following:
The 1/ standard is divided into old and new national standard GB, GB is to old O-ring diameter * wire diameter to represent the new national standard to the inner diameter of the rubber ring; * diameter represented by the current domestic enterprises mainly in the new national standard.
Old national standard: national standard GB1235-76--- line diameter: 1.9, 2.4, 3.1, 3.5, 5.7, 8.6;
New GB: national standard GB3452.1-92--- line diameter: 1.8, 2.65, 3.55, 5.3, 7;
2/ JIS B2401--- line diameter: 1.9, 2.4, 3.1, 3.5, 5.7, 8.4;
3/ method standard R--- line diameter: 1.90, 2.70, 3.60, 5.33, 6.99;
4/ American Standard AS568A, British standard BS 1806--- wire diameter: 1.78, 2.62, 3.53, 5.33, 6.99;
5/ German standard GB3452.1-92--- DIN3771 line diameter: 1.80, 2.65, 3.55, 5.30, 7;
6/ British standard BS 4518 Swiss standard 1586--- SMS line diameter: 1.6, 2.4, 3, 5.7, 8.4.
Three, O-ring specifications
Taiwan Asahi Meike seal (XOK), spot volume, standard size basically are in stock. And our strong technical force, can produce almost currently on the market a variety of diameter and wire diameter o-ring. The general size of the non - standard size is not close to the mold fee, unless the size is very large and the number of required is relatively small, will charge a small amount of die. Size: from 0.5~2000mm (special specifications can be customized); line size: 0.3, 0.5, 0.8, 1, 1.5, 1.78, 1.8, 2, 2.4, 2.62, 2.65, 3, 3.1, 3.5, 3.53, 3.55, 4, 4.5, 5, 5.3, 5.33, 6, 6.99, 7 8, 9, 10, 12, 13, 14, 15 etc.. A variety of O-ring applicable medium: oil, water, steam, water, acid and alkali resistance, freon, ethylene glycol etc.. Limit temperature: -60~250 degrees, pressure: 0~35MPa; if the long-term use temperature of 250 degrees centigrade, suggested the use of perfluorinated O ring, it is resistant to 1600 kinds of medium, excellent performance, the only drawback is that the fluorine is too expensive
