不同颜色的橡胶件件，其性能区别微小，但在不同的应用领域，可能对产品的外观有一定的影响。

我们储备的标准密封件主要是黑色，也有部分红色、绿色、墨绿色、褐色、浅蓝色等其他颜色，如果是直接购买，我们没有特别标明颜色的情况下，默认是发货黑色；

如果有特别的颜色需求，可来图来样定制。

The performance of rubber parts with different colors is slightly different, but in different application fields, it may have a certain impact on the appearance of products.

The standard seals we stock are mainly black, and some of them are red, green, dark green, brown, light blue and other colors. We deliver stock seals with black color if you don't  specify the color.  

If you have special color requirements, you can customize according to the drawings or  samples.
