PTFE Seals


PTFE Sheet - Virgin, Mechanical and Expanded grades

The perfect material for Food (FDA) applications. Chemical Compatibility 0-14 PH Good for Temperatures to 450F


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 Kevlar materials.  Kevlar enhances the physical properties of PTFE and results in a superior gasket material.  Ameri-lon shows less cold flow and greater sealing ability than other filled PTFE materials (PTFE) or Fluorocarbons.  It maintains the chemical attack resistance and the temperature range of PTFE.

Product equivalents to Gylon :  Ameri-lon 9810 = Gylon 3504 , Ameri-lon 9820 = Gylon 3510, Ameri-lon 9840 = Gylon 3500, Ameri-lon Expanded PTFE = Gylon 3450/3545, Amerilon PTFE = Gylon Chemrex 3570 *

Insertable PTFE Gaskets

Seal troublesome, corroded, pitted & steam-drawn flanges with these preformed gaskets.   100% P.T.F.E. preformed gaskets easily drop into your flange and seal it.  They are just as easy to remove after use.  Made to fit standard Ansi 150, 300, 400 and 600 lb. flanges in 1/2 through 12" sizes


PTFE Cut Gaskets

Virgin*     Mechanical Grade*      Expanded PTFE*
Gaskets cut from Virgin or mechanical grade material,  posses all of the great aspects of PTFE like chemical compatability and a 450-500F temperature range, but require torque to seal.  If that torque is not possible or if flange faces are worn or pitted,
Expanded PTFE , gaskets are the answer.

Full Face                   Ring Gaskets      

PTFE Bellows Expansion joints

Allow your chemical system to flex when it has to. Using PTFE expansion joints saves wear on your system and protects from pipe strain. Ideal when you have to deal with chemicals.

We provide Virgin and filled PTFE Rod, Tube and Bar stock.  Both in molded and extruded versions.

At American Seal & Packing we extrude a large range of standard size PTFE rod from 3/32" diameter to 5" diameter. We also have the capability to centerless grind intermediate sizes up to 2" diameter. Many of our sizes can be supplied in Virgin PTFE or with fills of glass, bronze, brass, carbon, graphite,  moly and a large range of colors.
