O-ring cords are extruded elastomeric sealing cords with a circular cross-section, designed for custom-fabricated static seals. These cords can be cut to length and bonded to form O-rings of non-standard sizes or used directly in groove applications for static sealing purposes. They are widely used in maintenance, machinery repair, and industrial manufacturing.
Applications:
-
Custom-sized O-ring production
-
Static sealing in flanges, covers, enclosures, tanks, and panels
-
Suitable for environments requiring resistance to specific chemicals, temperatures, or weather conditions
-
Frequently used in hydraulics, pneumatics, automotive, HVAC, and food processing equipment
