GYLON®, a product of Garlock Sealing Technologies, is a reinforced PTFE gasketing material that offers significantly reduced creep relaxation, cold flow, and excellent chemical resistance, along with easy identification due to branding and color coding.
GYLON® Style 3540 Benefits
- Tighter seal – highly compressible PTFE outer layers seal under low bolt load, while also conforming to surface irregularities such as pitted, scratched and warped flanges
- Excellent chemical resistance – service life is extended due to its ability to withstand a broad range of chemicals
- Easy cutting – soft PTFE can be easily cut from larger sheets, lowering inventory costs and costly downtime
- Effortless installation – rigid PTFE core is an asset, particularly on large diameter flanges or areas that are difficult to reach
