Custom Vulcanized Silicone O-Rings & Spliced O-Rings
Material Description
Elastostar manufactures custom vulcanized and spliced O-rings in Silicone, Viton/FKM, EPDM, Nitrile, and Neoprene for standard and non-standard sealing requirements.
Vulcanized O-rings are made by cutting and joining extruded rubber cord or profiles to create an endless ring.
This method is useful for large diameters, custom sizes, and applications where standard molded O-rings are not suitable.
Custom Size Vulcanized Silicone O-Rings & Spliced O-Rings
We manufacture custom O-rings in different diameters, cross-sections, and profiles based on drawings, dimensions, samples, or equipment requirements.
Custom vulcanized and spliced O-rings can support large-diameter seals, replacement parts, low-volume requirements, and non-standard applications.
When to Choose Vulcanized O-Rings
Vulcanized O-rings are a practical option when:
● Standard O-ring sizes are not available.
● Large or unusual diameters are required.
● Dedicated mold tooling is not practical for the required quantity.
Viton/FKM Vulcanized O-Rings
Viton/FKM Vulcanized O-Rings are suitable for demanding sealing environments involving heat, oils, fuels, lubricants, and many chemicals.
They can be manufactured in custom diameters and cross-sections for automotive, aerospace, chemical-processing, and industrial applications.
