A high performance gasket sheet of microcellular PTFE outer layers with a rigid PTFE core. Ideal for use in low-load flange designs, such as glass-lined equipment, but still suitable for standard ASME raised-face steel flanges.
Garlock GYLON® gasketing is a family of flat PTFE gasketing materials. GYLON® high-performance PTFE gasketing is manufactured using a proprietary process that imparts unique physical properties, which are not obtainable through conventional manufacturing methods: Designed for severe chemical service, color-coded for easy identification, superior sealability, which helps reduce process and media loss as well as fugitive emissions, reduced creep and cold flow characteristics, and patented thermal bonding process to fabricate virtually any size gasket. The innovative GYLON® gasketing process reorients the PTFE and fillers in such a way to increase the material’s tensile properties and decrease the creep relaxation problems that usually plague PTFE products. In addition, the mixing process creates a homogenous material with consistent, superior physical properties that, unlike inexpensive skived PTFE sheet materials, do not fluctuate from one side of the sheet to another.
*For flat face flanges, a minimum compressive stress of 1,500psi is recommended on the contacted gasket area for 150psig liquid service. Consult with the flange manufacturer to confirm that adequate compressive stress is available.
