Specification of Garlock Gylon 3545 PTFE with barium
Garlock Gylon 3545 PTFE
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 is designed to compress and conform to irregular or damaged surfaces, making it suitable for flanges that produce lower compressive stresses, such as glass-lined flanges and equipment.
FEATURES and BENEFITS Tight seals 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 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
SPECIFICATIONS Available in sheet or cut gasket form White Microcellular PTFE Conforms to FDA regulations and ABS specification Min.
