Factory supplier custom colored ringed flat square rectangle section silicone o ring
Custom Colored Silicone Sealing Rings with Specified Cross-Sections
Product Description
Round O-rings require inside diameter and cross-section. Square or rectangular sections require section width and height; flat annular gaskets require inside diameter, outside diameter and thickness. Include tolerances and the mating drawing.
Silicone is the material focus of this listing. NBR, FKM and EPDM alternatives require separate compound review for the actual service.




| Material: | Silicone compound selected for the specified sealing conditions |
| Hardness | Shore A hardness and tolerance per selected silicone compound and drawing |
| Mode of Production | Moulding process per seal profile, dimensions and selected silicone compound |
| Production Capabilities | Wide ranges of our machines including 150T,200T,250T, 300T and 500T |
| Size/Color | Profile dimensions and tolerances per drawing; color per agreed sample |
Application
Application of the rubber o ring:
A: Silicone rings for specified housings, grooves or mating faces; provide the sealing interface and installation details.
B: Square or rectangular cross-sections describe the section geometry, not necessarily the ring outline. Define both the outline and cross-section on the drawing before tooling review.
C: Confirm fluid formulation, temperature, pressure and motion for the selected silicone compound. Color and profile shape alone do not establish service suitability.
