Viton GLT O-Ring Resilience Study
Abstract
As part of an ongoing study of the resilience properties of O-ring materials made of Viton(registered), the properties of Viton GLT were compared with those of Viton B under comparable conditions. This study was the result of a contractor-proposed change in O-ring seal material. United Technologies Chemical Systems Division had proposed a change in the O-ring seal material used on the Titan solid rocket motor (SRM) clevis joint from Viton B to Viton GLT, a fluorocarbon elastomer with better low-temperature properties, in order to eliminate application of external joint heaters. The O-ring material made with Viton GLT was found to have significantly improved resilience and compression set properties under all conditions studied when compared to Viton B. Even under worst-case conditions, these properties exceeded even the best values obtained in a comparison study with Viton B. Based on these observations, Viton GLT is an excellent candidate for use in demanding applications that require both optimum resilience and compression set properties.
