Spliced and Vulcanized O-Rings

Large Diameter Seals

HydraPak's cutting edge vulcanization technology produces high quality seals with large diameter capabilities for your demanding applications. Vulcanizing is an excellent solution for non-standard sized O-rings and seals delivering greater strength and tighter tolerances.

Vulcanization is a heating and molecular bonding process-profile ends are fused together using heat, rubber adhesive, pressure, and time to chemically bond the joint, creating a continuous seal. Vulcanization causes the polymer chains in rubber to become crosslinked. The polymer chains can no longer move independently, which allows the material to stretch under stress and return to original form when the pressure is released. This results in a stronger, more stable seal suitable for a wider range of applications.

Spliced and vulcanized O-rings are made from extruded cord stock that has been cut to length and bonded together to create a continuous seal. Spliced and vulcanized O-rings can be manufactured quickly without the cost and lead-time associated with tooling. Spliced and vulcanized O-rings are a great alternative to molded O-rings when non-standard or custom diameters are needed.

Spliced and Vulcanized O-Ring Benefits:

Large diameter profiles that cannot be molded
High bond integrity
Strong joints that are nearly undetectable
No tooling costs
Custom sealing applications
Produced on-demand with a fast turnaround
