Vulcanized 'O' Rings, 'O' Ring Cord
 

Vulcanized 'O' Rings

We produce Non-Standard size 'O' Rings by bonding two ends of 'O' Ring cord together under a pre-determined temperature and pressure. An elastomeric bonding agent which matches the polymer of the cord provides a very strong bond, uniform temperature capability and media resistance. These parts are recommended for static applications only. Cord Cross Section Minimum Inside Diameter
