Ameri-lon Physical Properties (printable)

Ameri-lon a new family of products using a new hybrid material, Ameri-lon is the result of years of experience in producing PTFE materials.  It is designed for a wide range of demanding industrial requirements including gasket and bearing applications.  Ameri-lon is filled PTFE, uniquely combining the properties of PTFE and Fller materials.  The Filler enhances the physical properties of the PTFE and results in a superior gasket material.  Ameri-lon shows less cold flow and greater sealing ability than other filled PTFE materials  or Fluorocarbons.  It maintains the chemical attack resistance and the temperature range of other PTFE  based sheets.

Ameri-lon is available in a wide range of products including gaskets, sheet, molded tube and rod as well as finished and machined items

Ameri-lon can be considered as an equivalent to the Garlock Gylon Product range.  The interchange for the Gylon products is as follows:


*Ameri-lon 9504 = Gylon 3504

*Ameri-lon 9510 = Gylon 3510

*Ameri-lon 9500 = Gylon 3500

*Ameri-lon Expanded PTFE = Gylon 3450/3545

*Amerilon  PTFE = Gylon Chemrex 3570

* This is to be used as a general guide only.  All applications should be considered individually based on the temperature, pressure, media being sealed, Ph, gasket dimensions, torque load, bolt size and any other factor effecting the gasket.  For assistance in determining the suitability of an application contact our technical staff at American Seal & Packing. No application should be undertaken by anyone without independent study and evaluation for suitability. Never use more than one gasket in one flange joint, and never reuse a gasket. Improper use or gasket selection could cause property damage and/or serious personal injury.
