PTFE (polytetrafluoroethylene), also known as Teflon, is a perfect sealant. Its good heat resistance up to 280°C, outstanding chemical resistance and low friction coefficient permit application of PTFE yarn both in stuffing boxes of pumps and fittings. Addition of incorporated graphite improves thermal conductivity and reduces tendency of PTFE to squeeze in gaps between the shaft or the spindle and stuffing box enclosure.
All information in this catalogue is based on years of experience in manufacture and use of the discussed products. Since sealing performance in the joint is subject to multiple factors such as mounting method, system parameters, and sealed medium, technical parameters specified herein are of informative nature only and cannot be used as grounds for any claims; any special uses of products are subject to consulting with the manufacturer.
