Wide Range Of Section Flat Square Round Rectangle Silicone Ring Rubber Seal
Silicone Rubber Seal Rings with Round, Square and Rectangular Sections
Product Description
For a round section, provide inside diameter and cross-section. For a square or rectangular section, provide inside and outside dimensions, section width and height, with tolerances and corner requirements.
Silicone options can be discussed for the required profile and service conditions. NBR, EPDM and FKM alternatives require compound selection for the actual fluid and temperature.


| Material: | Silicone, NBR, EPDM and FKM options; specify the compound for the drawing and service conditions. |
| Hardness | 40–90 Shore A options; confirm hardness for the compound and profile |
| Mode of Production | Compression, injection, injection transfer, extrusion, silicone liquid injection |
| Production Capabilities | Wide ranges of our machines including 150T,200T,250T, 300T and 500T |
| Size/Color | Specify round, square, rectangular or flat section on the drawing. Agree dimensions, tolerances, corner radii and color before tooling or sample production. |
Application
Application of the rubber o ring:
A: Round-section rings: confirm inside diameter, cross-section and groove dimensions to evaluate sealing compression.
B: Square, rectangular and flat sections: provide section width, height and corner details. These profiles require their own groove or flange dimensions.
C: Material selection: identify the fluid, temperature, pressure and movement for each profile. Section shape alone does not establish chemical compatibility or a pressure rating.
