GYLON® Gasketing Style 3545
Microcellular PTFE Gasketing for Low Bolt Load Applications
The GYLON® Style 3545 is a highly compressible microcellular PTFE with a rigid PTFE core for improved handlability. The GYLON® 3545 designed to compress and conform to irregular or damaged surfaces, making it suitable for flanges that generate lower compressive stresses, such and glass-lined flanges and equipment.
- Tight seal
- Highly compressible PTFE outer layers seal under low bolt load
- Compressible layers conform to irregularities, especially on warped, pitted, or scratched flanges
- Rigid PTFE core reduces cold flow and creep
- Withstands a wide range of chemicals
- Can be cut from larger sheets, reducing inventory costs and expensive downtime
- Rigid PTFE core facilitates installation, especially on large diameter flanges and hard-to-reach areas
- Will not support flame
- Will not support bacterial growth
- Available in sheet or cut gasket form
- White
- Microcellular PTFE
- Conforms to FDA regulations and ABS specification
- Min. Temperature: -450°F / -268°C

- Low bolt load applications*
*For flat face flanges, a minimum compressive stress of 1,500 psi is recommended on the contacted gasket area for 150 psig liquid service. Consult with the flange manufacturer to confirm that adequate compressive stress is available.
† When sealing uneven flanges, gasket must be four times thicker than maximum gap between flanges.
