1. O type and small size O type 0.8*0.7.
1. Imported small size O ring 0.8*0.7 is easy to install. Owing to the simplicity of the O-ring itself and the standardization of its installation, installation and replacement are very easy.
2. O-type rubber sealing ring has simple structure, good sealing performance, self-sealing effect and reliable sealing performance.
3. O-type rubber seals are widely used to seal oil, water, air, gas and various chemical media effectively by selecting suitable rubber materials and proper formula design. The temperature can be used in a wide range - 60 ~220 ~C, and the pressure can reach 1500Kg/cm2 (used with reinforcing ring) when fixed.
4. O rubber seals are rich in materials and suitable for all kinds of materials. The sizes and grooves are standardized.
Two, XOK Taiwan brand seals
Taiwanese brand seals give the overall impression that the product has high precision and stable quality, but the price is not too high, more practical. After years of development, Taiwan Xumeike Seal has formed a comprehensive manufacturer of various kinds, specifications, large stock, according to the special requirements of customers to order a variety of rubber sealing sundry parts. The standards for sealing products are: French standards, German standards, Japanese standards, American standards, Chinese national standards, etc. The diameter of the imported O ring can be produced from 0.3~20, and the inner diameter can be customized from 0.6~2200. The material of the sealing ring is all made of famous brands such as the United States, Japan and Germany. Such as perfluorinated rubber FFKM, fluorinated rubber FPM / FKM / VITON, PU, NBR, EPDM, hydrogenated butadiene green rubber HNBR, silica gel SIL, etc. The temperature range varies from -60~250 C to material. And the products in ozone resistance, high and low temperature resistance, strong acid and alkali resistance, wear resistance, anti-aging and other aspects have a more prominent performance. All products conform to RoHS, UL and other certification.
Three. Selection of 0.8*0.7 material for imported small size O ring:
It has important significance for its sealing performance and service life. The properties of the material directly affect the performance of the O ring. In addition to the general requirements for sealing ring material, the O ring should also pay attention to the following conditions:
1) resilience and resilience.
2) appropriate mechanical strength, including expansion strength, elongation and tear strength.  
3) stable performance. It is not easy to expand in the medium, and the heat shrinkage effect (Joule effect) is small.  
4) easy to machine and shape, and maintain precise dimensions.
5) do not corrode contact surfaces, do not pollute media, etc.
