Black Acid And Alkali High Temperature Resistant FKM FPM Fluorelastomer O-Rings

We are manufacturing and trading combo in China, we supply o-rings made by different materials/compound, such as NBR, FKM, EPDM, SIL and so on. Of course, the o-rings also can be made by different colors as you like.

But what is an o-ring? A lot of people misunderstand this, I can show you a draft drawing to understand this.

We can see on the drawing, the cross section looks like an "O", so we call it o-ring. 
On the drawing, "OD" means outer diameter, "ID" means inner diameter, "CS" means cross section. There is a formula as bellow:
OD = ID + 2×CS, and we usually show an o-rings as ID*CS.
 

Why choose us? I can show you our ADVANTAGES as bellow:
